Recommended settings

  • Incoming IMAP server = mail.infomaniak.com
  • IMAP port = 993 (with SSL)
  • Outgoing SMTP server = mail.infomaniak.com
  • SMTP port & encryption protocol and command/method to activate this protocol: 587 + STARTTLS
  • Username = the complete email address & (need help?)
  • Password = the password generated for the email address you want to access (❓: my kSuite | Mail Service/kSuite).
  • Authentication required for sending emails:
    • Enable this in the SMTP settings of your application.
    • Check "use the same settings as the incoming server" or, depending on the software/email client, enter a username (the complete email address) and the generated password.

Refer to this other guide if you are looking for information about other email ports and protocols that are supported (SSL/TLS, for example).

 

In case of a problem

Check that the Mail service is configured optimally.

It is not necessary to contact Infomaniak Support if your email address works correctly outside the application. The most common error concerns the use of an incorrect password. The troubleshooting guides will help you resolve any potential issues:
