This guide helps you identify and correct most email errors encountered after sending an email to a recipient.
Instead, please refer to this guide if the error occurs while setting up an email address in a software/email client.
Why an Email Error?
Generally, an email error message results from:
- a misconfiguration of the domain name used with your email service
- a problem with your recipient's (mail provider)
In any case, a delivery failure report (Mailer Daemon or Mail Delivery Subsystem) containing the explanation is sent to the sender.
Finding and Identifying the Email Error
When your message fails to reach your recipient, an initial failure report (Temporary Delivery Failure Report
) is sent and specifies that the server will attempt to resend your message multiple times.
A final non-delivery report (Final Delivery Failure Report
or Undeliverable Mail
) issued by the recipient's server is sent to the sender (via an Infomaniak mail server, hence the mention of Infomaniak at the beginning of most error messages you may receive) to inform them that the email could not be delivered even after multiple attempts.
The notification always includes the reason for the failure. Example below:
This is the mail system at host smtp-1-1234.mail.infomaniak.ch.
I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below.
For further assistance, please send mail to postmaster.
If you do so, please include this problem report. You can delete your own text from the attached returned message.
The mail system anna.a@abc.xyz: host mxbw-abc-xyz.abc-ab12.abc.ch[123.456.789.00] said: 550 5.1.1
anna.a@abc.xyz recipient rejected, account administratively disabled (in reply to RCPT TO command)
Here, the recipient's address is apparently suspended by their email provider (account administratively disabled
).
Sometimes, you need to look for the reason for the error message among its attachments (often a plain text file). Example:
Reporting-MTA: dns; mxbw.abc.ch [123.456.789.00]
Received-From-MTA: dns; smtp-1-1234.mail.infomaniak.ch [12.345.678.99]
Arrival-Date: Tue, 01 Aug 2023 15:49:22 +0200
Final-recipient: rfc822; anna.a@abc.xyz
Diagnostic-Code: smtp; 552 RCPT TO:anna.a@abc.xyz Mailbox disk quota exceeded
Last-attempt-Date: Tue, 01 Aug 2023 15:49:22 +0200
Here, the external recipient's mailbox at Infomaniak appears to be full (Mailbox disk quota exceeded
).
Most Common Cases
SPF Failure
The SPF (Sender Policy Framework) record is not properly configured:
Subject: Delivery Status Notification (Failure)
From: Mail Delivery System mailer-daemon@domain.xyz
To: Anna.A anna.a@abc.xyz
This is an automatically generated Delivery Status Notification.
Delivery to the following recipient failed due to SPF failure:
anna.a@abc.xyz
Technical details of SPF failure:
The sender's domain domain.xyz does not have a valid SPF record. Please contact your email administrator to correct the SPF configuration.
Solution: check your domain name configuration and especially the SPF record if your website is hosted by Wix or another provider. Learn more (click here)
User Unknown
The email address specified in the message is invalid or does not exist:
Subject: Delivery Status Notification (Failure)
From: Mail Delivery System mailer-daemon@domain.xyz
To: Anna.A anna.a@abc.xyz
This is an automatically generated Delivery Status Notification.
Delivery to the following recipient failed permanently:
anna.a@abc.xyz
Technical details of permanent failure:
The email address does not exist. Please check the recipient's email address and try again.
Solution: carefully check the recipient's email address and correct it if necessary; ensure you are using a valid email address for the recipient.
Temporary Failure
The recipient's mail server is experiencing temporary issues or is unavailable.
Solution: wait for some time, then try sending the message again later. If the problem persists, contact the recipient's technical support for assistance.
Blocked by SPAM Filter (or Content Rejected)
The recipient's mail server blocked the message due to anti-spam filtering rules:
Subject: Delivery Status Notification (Failure)
From: Mail Delivery System mailer-daemon@domain.xyz
To: Anna.A anna.a@domain.xyz
This is an automatically generated Delivery Status Notification.
Delivery to the following recipient failed due to the message being rejected as spam:
anna.a@domain.xyz
Technical details of delivery failure:
The content of the message triggered the spam filters of the recipient's email server. Please review the message content and try again.
Solution: check if your message contains elements likely to be considered as spam (keywords, suspicious links, etc.). Contact the recipient to verify if the message was filtered into the spam folder.
Read this guide on outgoing spam and this guide on incoming spam.
Bad Reputation
The recipient's mail server blocked the message due to anti-spam filtering rules:
gmail-smtp-in.l.google.com said: 550-5.7.1
Our system has detected that this message is likely suspicious due to the very low reputation of the sending domain.
To best protect our users from spam, the message has been blocked.
Please visit https://support.google.com/mail/answer/188131 for more information.
Solution: check the reputation of the domain, determine if there has been recent misuse of one of your email addresses for malicious purposes, e.g.
Domain Not Found (or DNS Error)
The recipient's domain name could not be resolved or does not exist.
Solution: check the spelling of the recipient's domain and correct it if necessary; ensure that the domain name and DNS are valid and active.
Mailbox Full
The recipient's mailbox is full, preventing the reception of new messages.
Solution: inform the recipient of the situation and ask them to free up space by deleting emails or archiving items.
This cannot happen with email addresses managed by Infomaniak since they do not have a storage size limit.
Part of their network is on our block list
If the error message (typically obtained after sending from an online tool hosted on the server where your website is located, e.g., a confirmation from Prestashop or another online store you manage) contains:
host hotmail-com.olc.protection.outlook.com[104.47.30.97] said: 550 5.7.1
Unfortunately, messages from [89.123.456.789] weren't sent. Please contact your Internet service provider since part of their network is on our block list.
Solution: change the method of sending emails. The sending is unauthenticated and comes from a specific IP address which is apparently blocked by the recipient for some reason (Infomaniak does not intervene to request unblocking). Therefore, configure the online tool to perform authenticated sends.
Less Common Errors
Deferred - Delayed
The error message Deferred - Delayed - Warning: message still undelivered after 4 hours, Will keep trying until message is 3 days old
means that the Infomaniak mail server tried to connect to your recipient's mail server to send the message but for some unknown reason, it was unsuccessful. This error message specifies that the Infomaniak server will continue to try to send your message for the period specified in the error message. If after this period the message is still not delivered, you will receive a final error message informing you that your message could not be delivered and your recipient did not receive it.
Greylisting Delay
This Greylisting Delay
error occurs when your recipient's mail server uses, like Infomaniak, a technique called "greylisting" which imposes a temporary delay on the first attempt to deliver a message from an unknown sender. The Mailer Daemon may eventually send an error report indicating that delivery has been delayed due to greylisting. The error may also mention banned sender
. Retry your sending a few minutes/hours later.
Message Size Exceeded / File Too Large
These Message Size Exceeded / File Too Large
errors occur when the size of the message (or attachments) exceeds the limit allowed by the recipient's mail server. The Mailer Daemon will return an error report indicating that delivery failed due to exceeding the message size.
Rate Limit Exceeded
This Rate Limit Exceeded
error occurs when the sender has exceeded the rate or volume limit allowed by the recipient's mail server. Mail servers may impose limits to prevent spam or system overload.
Malware Message Rejected
This Malware Message Rejected
error occurs when the message contains an attachment, a link to a storage site like Dropbox, or dynamic content including in the "forwarded" part of the message (e.g., in a forwarded message). Try resending the message from Infomaniak Mail instead of a mail application, and remove any content that could trigger this error.
The Message Contains a Unicode Character in a Disallowed Header
This The message contains a unicode character in a disallowed header
error may appear if you have inserted a special character like a heart ♥ e.g., in the body of the mail, the subject, or especially in the full name; the risk of being rejected by providers is very high: keep the use of symbols, characters, and fonts as simple as possible.

This guide details how to retrieve missing e-mails recently (mistaked by the user, e.g.).
Preamble
- Infomaniak keeps 7 separate backups (= 7 key) of the content of each email address.
- The backup is performed once a day.
- It is therefore possible to return the mailbox as it was in the last 6 or 7 days.
- ELEMENTS RECOVERED:
- E-mails no longer existing when you request restoration will be handed over to their original location.
- Some parameters linked to your e-mail address (part "answering machine" and part "redirection" in particular) will also be restored if they have changed in the meantime.
- ELEMENTS NOT RECOVERED:
- E-mails Displaced and not deleted will not necessarily reappear at the expected place since they still exist somewhere in the tree of the mail account - it is necessary to search.
- Backup restoration does not includecalendar and/or Address book.
- E-mails not yet present or more existing at the time of execution of the daily backup (also read the POP3 chapter below); example: an e-mail arrived at 8am, deleted at 9am while the backup took place at 5am.
- ELEMENTS NOT MODIFIED:
- The e-mails arrived, received, created and stored in the different folders (messages sent e.g.) in the interval (between the date you want to return and the date you perform the restoration) are not affected, they remain present.

E-mails stored in unconventional folders
If you store your messages in folders with unusual names (e.g. named folders) Recycle Bin or Spam) take note of the important information this other guide on this subject.
Software users/mail client configured in POP3
If you are used to raising your mailbox with an email software/client like Outlook and the latter is configured with the POP/ POP3 protocol, you will not be able to restore everything since the backup is done once a day, it only keeps the messages that were found at the time of backup in the Infomaniak inbox; idem for your other folders (Messages sent (e.g.) present in the POP3 application: these are not synchronized with Infomaniak and therefore are not saved; it is therefore necessary in the future prefer IMAP protocol in your mail client/software.
This guide helps you find solutions if you send an email from an email address hosted by Infomaniak and the message unintentionally ends up in your recipient's Spam folder.
Use Email Wisely
When basic rules are followed, there is little risk of your message ending up in the recipient's spam folder. To do this:
1. Use a Valid Email Address
Ensure that your email address and its domain are correct and valid; check the security settings of your domain name. If you correct a setting, wait 24 hours before trying to resend your email.
2. Avoid Suspicious Content
Whether in the subject of the message or in the body of the email, avoid using words or phrases often associated with spam, generic messages, overly complicated layouts, and unsafe or poorly formatted internet links. Personalizing an email using the recipient's name strengthens the legitimacy of your messages.
Sending suspicious attachments or large attachments can lead to the Spam folder; use SwissTransfer for example.
3. Test Sending from Mail Infomaniak
If you send your messages from email software, try sending them from mail.infomaniak.com to more precisely identify the origin of the problem leading to spam.
4. Reputation of Custom Domain
If you send emails from an address @domain.xyz and that domain has for any reason recently obtained a " bad reputation", your messaging will be impacted and may be considered as Spam by various providers. It is necessary to address the reasons that led to the depreciation of your domain name.
5. Obtain Consent
Make sure you know the person you are writing to, or at least write to a user likely to expect your message so they don't mark it as Spam. For group and/or regular mailings, voluntary subscriptions reduce the risk of being classified as spam; also consider Infomaniak's Newsletter solution.
6. Optimize Sending Frequency
An excessive volume of sending to several recipients from the same provider can be considered spam. Respect a reasonable frequency when sending your emails.
7. Get Added to Infomaniak's Whitelist
If you regularly send emails to a recipient also hosted by Infomaniak, and your messages are suddenly considered spam, your recipient can add your email address to the whitelist to allow your mail to reach their normal inbox. But it is important to pay attention to the reasons that led your messages to spam because not everyone will be able to whitelist your address.
This guide explains how to activate incoming mail filtering, automatically categorize advertising messages, and report certain fraudulent messages to reduce spam on an email address managed by Infomaniak.

This guide details the different identifiers that you will have to use with Infomaniak, and what happens if one of the passwords is changed.
Preamble
- As with many other online services, you identified yourself with Infomaniak when registering with a personal email address.
- This personal email address serves you as login ID when you want to connect to Infomaniak services.
- This login ID has its own password (which you chose when creating your Infomaniak user account - your personal email address, read above).
There's no connection between...
- ...that couple Identifier / password described in points 1/2/3 above...
- ... and the email addresses you created or subsequently obtained from Infomaniak.
Only one report could exist if the spelling is the same (e.g. you signed up with the email address toto@abc.xyz and you also manage the email address toto@abc.xyz to Infomaniak) but even in this case, the password will most likely be different, once for the login identifier toto@abc.xyz and once for the email address toto@abc.xyz.
When should we specify...
...the connection identifier?
- Let it be for sure. mail.infomaniak.com or app Infomaniak Mail, it is essential to connect with...
- ... the identifier of your Infomaniak user account...
- ... and sound password.
- ⚠This will NOT work by directly indicating an email address and its password (if no user account exists with the same spelling and password).
This is why it is advisable to register with Infomaniak with its personal address such as that offered by your Internet service provider (Orange, Sunrise, Free, etc.) or that of provider like Yahoo etc.
...the e-mail address?
- In an email software/client (such as Microsoft Outlook, Apple Mail, etc.) you need to enter...
- ...the email address you would like to consult...
- ...and its password.
- ⚠This will NOT work by indicating the password you use to log in to the Infomaniak interface because this password is very likely different!
So if connecting to a page like mail.infomaniak.com works with toto@abc.xyz (and the password you have just changed, e.g.) it does not in any way mean that viewing the address toto@abc.xyz on your regular mail client/software should only work because you entertoto@abc.xyzAnd the password you've just changed that works to access the tools on the Web...
Solve a connection problem
It is not necessary to contact Infomaniak Support (which does not have any of your passwords) if...
- ... you do not manage to connect to interfaces such as mail.infomaniak.com or manager.infomaniak.com for a wrong password question...
- The only solution is reset the login password.
- ... you can't connect your email address to your email software/client (such as Microsoft Outlook, Apple Mail, etc.) for an incorrect password question:
- Test the couple's email address / password to check if an error is mentioned.
- Reset the password of the email address where applicable.
To be retained
In summary, you have:
- 1 login (in the form of an email address) and 1 password to access...
- ... in the Mail https://mail.infomaniak.com/
- ...to the Manager https://manager.infomaniak.com/
- 1 password for each email address hosted by Infomaniak
These two informations may or may not be the same depending on your choice. And if you change one, it will not necessarily change the other unless it has been unified (this will be specified to you - read below).
In which case are passwords unified?
Suppose that within the Mail Service you own in your Infomaniak account, you create an email address named julie@entreprise-familiale.xyz (password 123-Abc).
If then a Infomaniak account...
- ... is created with the same title (julie@entreprise-familiale.xyz - password whatever)...
- ... is the only account to consult the email address julie@entreprise-familiale.xyz via mail.infomaniak.com
- ... has sufficient permissions to change the password of the email address...
... then the unification of the password will be proposed when you will proceed to change the password of the email address from the Infomaniak account in question.
What about the other IDs?
Acquiring other Infomaniak products involves obtaining other identifiers such as those for connections FTP, MySQL, SSH, WebDAV, etc. but they are Fully independent of the two types of identifiers described above.
This guide explains how to access your devices Address books Infomaniak and calendars / calendars Infomaniak.
Be aware of this other guide if you are looking for information on the synchronization of your e-mails.
Preamble
- The Web app Contacts (management of your Address books Infomaniak for all your professional and personal contacts) and the web app Calendar (management of your calendars / calendars Infomaniak for all your events and appointments) can be synchronized so that their content (hosted on Infomaniak servers) appears on your personal devices.
- If your current contacts & calendars are not yet managed within these Infomaniak applications, it will first be necessary to import your data for synchronization to work later.
- The suggested timetables can also be synchronized with your mobile and desktop devices.
- The calendar of anniversaries (calendar that displays the anniversary dates of your contacts when the date is indicated on their address book card) is only visible through calendar.infomaniak.com and cannot be synchronized with CalDAV tools.
Synchronize contacts & calendars (CardDAV/CalDAV)
Click here to open the Infomaniak wizard to configure the synchronization of your Apparatus (macOS, Windows, Linux, Android, iOS) and Common mail software/clients (Outlook, Microsoft 365, Thunderbird, Apple Mail, eM Client, etc.).
Specific guides
OS | Application to be synchronized |

⚠The Infomaniak services are compatible with any application that supports CardDAV/CalDAV. For further assistance contact: support of the software used or partner — discover also the role of the host.
This guide explains what are the protocols and ports that can be used with e-mail services Infomaniak (Mail Service In particular).
Mandatory Ports and Parameters
When you are asked to do so during a Software configuration or mail application, only use these parameters:
IMAPs - incoming mail | SMTPs - outgoing mail | |
---|---|---|
Ports | 993 | 465 |
Authentication | SSL / TLS | SSL / TLS |
Server Name | mail.infomaniak.com | mail.infomaniak.com |
In case you specify other indications,mail errors may occur.
Other supported but not recommended protocols
- port
143
(standard port for Receipt Messages via IMAP) - port
110
(standard port for Receipt Messages via POP3) - port
995
(secure port for Receipt Messages via POP3s) - port
587
(alternative port not recommended for consignment Messages via SMTP) - TLS authentication on SMTP 587 and 25 ports
- STARTTLS authentication for IMAP, POP3 and SMTP
- SMTP authentication (either LOGIN or PLAIN)
TheInfomaniak API does not offer any connection to the mail because IMAP and SMTP are the "API"; for this purpose use a python library as https://docs.python.org/3/library/email.examples.html and https://docs.python.org/3/library/imaplib.html or any library using IMAP and SMTP.
To display emails from php:imap_open("{mail.infomaniak.com:993/imap/ssl}", $email, $password);
The mechanism MTA-STS
is not set up or verified, Infomaniak using instead DANE which guarantees a encrypted connection under these conditions:
- The customer sends an e-mail to a domain that has
DANE
. - The client receives an e-mail from a SMTP server that
DANE
. - In all other cases, it will be a random connection that does not guarantee 100% that the connection will be encrypted.
