This guide concerns files attached by your correspondent that appear in the winmail.dat format when they arrive at your Infomaniak-managed email address.

These files are in no way dependent on the incoming or outgoing mail provider. It is a Microsoft-specific issue, as indicated on their support page or this page (in English).

What is winmail.dat?

The issue with "winmail.dat" attachments is quite common and can occur when sending emails from Microsoft software/clients such as Outlook. The "winmail.dat" format is used to encapsulate formatting information, attachments, and contacts within the message. However, this can cause problems when recipients use other software/clients that cannot correctly interpret this format.

Resolving the Attachment Reading Issue

Ask the sender to:

1. Resend the message without using the "winmail.dat" format, by using a standard email format such as HTML or plain text when sending messages, and/or disabling RTF formatting in Outlook settings before sending the email:

2. Disable sending in RTF format for recipients who are not using Microsoft software/clients. To do this, they need to open your contact record in their contact list, go to the "Email Address" tab, and select "Send in plain text only"
3. Compress the attachment into a standard zip file before sending it
4. Use another software to send their message, such as Thunderbird, for example

If you do not wish to contact them again:

1. Use free websites and online tools to decrypt the content and convert the "winmail.dat" file into a more or less readable format

This guide explains how to obtain your email addresses from the Swiss hosting provider Infomaniak.

Introduction

• It is no coincidence that Infomaniak manages several million email addresses:
  • unlimited storage space
  • hosted in Switzerland by a neutral and independent company
  • synchronization of contacts & calendars across all devices
  • online access to your emails with Mail (mail.infomaniak.com) and the Infomaniak Mail app
  • professional Newsletter tool
  • professional anti-spam and antivirus filter for inbound and outbound
  • permanently backed up

Is a domain name required?

Except for the free @ik.me email offer (+ etik.com, etc.), an email address at Infomaniak is always created within a Mail Service, and this Mail Service revolves around a domain name which must exist and be configured for the email service to work.

Example: If you want the address jean.dupont@domain.xyz ‍, you need to:

1. own the domain name "domain.xyz"
2. obtain a Mail Service "domain.xyz"
3. create the email address "jean.dupont"

All of this is offered and requested during the ordering process on infomaniak.com (see below), preceded by the mandatory creation of a user account (for which you will need to provide your personal email address, or an already existing address in any case).

If the corresponding domain name is already registered with an external registrar, you may need to provide the correct MX records in the DNS zone.

This guide details sending authenticated emails from a website hosted by Infomaniak using SMTP configuration; the setup of an authenticated SMTP server is presented for the main CMS.

Using authenticated SMTP to send emails from your applications offers advantages in terms of security, reliability, error management, compatibility with third-party servers, and traceability compared to using unauthenticated PHP mail.

Prerequisites

• own a mailing service; you have the option to use the Mail Service offered by Infomaniak or any other mailing service of your choice
   

Example of SMTP Configuration

on WordPress

1. log in to the WordPress admin dashboard
2. install an SMTP plugin (WP Mail SMTP works)
3. configure the plugin, e.g.:
   ‍

From then on, an email sent from a contact form present on the site (default Divi form e.g.) will be sent via SMTP. To verify, simply check the headers of a message received this way, especially the x-mailer line which may mention, for example, WPMailSMTP/Mailer/smtp instead of PHPMailer.

on Prestashop

1. log in to the Prestashop admin dashboard
2. go to Advanced Parameters then Email
3. configure sending via SMTP:
   

Then check (to avoid an error like Could not instantiate mail function or sender mismatch) that the address you configured in these advanced settings matches the address used by Prestashop when sending emails. To do this:

1. log in to the Prestashop admin dashboard
2. go to Store Settings
3. click on Contact in the left sidebar
4. in the Contacts tab, verify that the email address mentioned is the same as the one configured earlier

This guide explains how to report a phishing attempt you may have fallen victim to.

Phishing, Fishing, Scamming...

Phishing is a fraud and scam attempt aimed at obtaining sensitive information in a fraudulent manner.

Typically, the victim receives a message in their email that appears to be from Infomaniak, their bank, or a trusted organization, indicating that a problem has occurred with their account.

 

The purpose of this identity theft is usually to voluntarily direct the user to a page and communicate private information that will then be exploited for various purposes, mainly financial.
 

Prerequisites

• check that the spam filter is active
• for added security, activate the external mail tag

How to Report a Phishing Email

To do this:

1. log in to Infomaniak Mail (mail.infomaniak.com) from a web browser like Brave or Firefox
2. open the phishing message and click on the action menu ⋮ on the right
3. from the menu that appears, select Report as phishing:
   
   
   
    
4. confirm to send for processing
5. delete the email

Once you have clicked on Report as phishing, an email is automatically sent to Infomaniak with all the necessary information for handling the scam report.

In case of a more serious problem (when the message is directly addressed to you by an acquaintance or a contact without it being a large-scale sending) it is recommended to reach out to an organization like www.report.ncsc.admin.ch.

This guide explains how to add or modify one or more SPF records in the DNS zone (of a domain name) managed in the Infomaniak Manager.

Introduction

• if your domain name is registered with Infomaniak, your email is managed by Infomaniak, but your website is hosted with another provider (e.g., Wix), you probably manage the DNS zone (and thus the SPF) with that other provider: read this guide for more information

Understanding SPF Records

The SPF (Sender Policy Framework) record type is a standard for verifying the domain name of an email sender and aims to reduce SPAM.

It serves to indicate which server is allowed to send emails for a domain.

If the SPF fails for an email, it means that the email was not sent from a server/IP address authorized by the sending domain administrator.

The email is then considered spam.

Moreover, Infomaniak automatically sets up this type of record when creating a Mail Service for your domain (strict SPF):

• v=spf1 include:spf.infomaniak.ch -all

Thus, the recipient's server of the email you send will evaluate that any mail not coming from Infomaniak servers will be rejected. This prevents malicious parties from spoofing email addresses from your domain name.

However, you can also decide to modify the SPF to a more flexible model:

• v=spf1 include:spf.infomaniak.ch ?all

In this case, the recipient's server of the email you send will evaluate according to its own rules whether it accepts emails not coming from Infomaniak servers.

To summarize:

• ?: the receiving server accepts the message even if the sender is not listed in the SPF
• ~: the receiving server generally accepts the message if it is not listed in the SPF but identifies it as suspicious
• -: the receiving server rejects the message if it is not listed in the SPF (recommended)

Add an SPF via a TXT Record

Refer to this guide (click here) for instructions on managing records in a DNS zone.

Add Multiple SPF Records

If you are using email providers in addition to Infomaniak, you need to obtain their SPF and then merge it with Infomaniak's according to a specific syntax.

Example of 3 SPF records:

• Infomaniak's: v=spf1 include:spf.infomaniak.ch -all
• those from 2 secondary providers:
  • v=spf1 include:the-second-domain.xyz ?all
  • v=spf1 include:the-other-domain.xyz ~all

... the final SPF to insert into your DNS zone should be in the form:

• v=spf1 include:spf.infomaniak.ch include:the-second-domain.xyz include:the-other-domain.xyz -all

Remove any other SPF entry from your domain's DNS zone!

Check the SPF Record

The Global Security tool allows you to easily check and correct certain problematic records.
