Ports to use for messaging
This guide explains which protocols and ports can be used with Infomaniak messaging services.
It is essential to only use the mail.infomaniak.com server for incoming and outgoing mail, otherwise errors may occur.
Recommended Ports
We recommend using the following protocols and ports:
- port 993 (secure port for receiving messages via IMAPs )
- port 465 (secure port for sending messages via SMTPs )
Enable SSL/TLS authentication when setting up your software or application.
Other supported protocols
- port 143 (standard port for receiving messages via IMAP )
- port 110 (standard port for receiving messages via POP3 )
- port 995 (secure port for receiving messages via POP3s )
- port 587 (alternative port for sending messages via SMTP )
- TLS authentication on SMTP ports 587 and 25 (not recommended)
- SMTP authentication (either LOGIN or PLAIN)
- STARTTLS authentication for IMAP, POP3 and SMTP
To view emails from php:imap_open("{mail.infomaniak.com:993/imap/ssl}, $email, $password)
