Auto-discovery for eM Client (via IMAP / POP3, CalDAV & CardDAV)

This article was built using eM Client 7.

eM Client attempts Auto-discovery (IMAP, POP, SMTP, CalDAV, CardDAV) only via HTTPS.

SSL connections (HTTPS, IMAPS, POP3S, and SMTPS) will work only if TLS 1.0 is enabled.

If HTTPS Auto-discovery connection fails (using POST), it will fail over on HTTP (using GET) — this will also fail as Axigen does not support this method.

1. In axigen.cfg, set to "yes" the flags that enable Auto-discovery for the desired protocol and provide the hostnames and ports corresponding to the IMAP(S) / POP(S) and SMTP(S) protocols, to be advertised by Auto-discovery.

2. In your DNS server, configure an entry with the name autodiscover.youremaildomain.tld, such as:

If you perform a custom configuration:

enableIMAPAutodiscovery = yes
enablePOP3Autodiscovery = yes
enableSMTPAutodiscovery = yes

eM Client will automatically choose IMAP over POP3.
