Resolve a certificate error that cannot be verified

This guide helps you resolve the mail error "The server you are connected to is using a certificate that cannot be verified".

Solution

The above error message appears in your email software/client because you are using IMAP/POP/SMTP server names of the form mail.domain.xyz with SSL enabled, while the SSL certificate is only valid for our domain infomaniak.com.

Therefore, you should only use mail.infomaniak.com as the incoming and outgoing server to use SSL on the connection. Learn more
