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.

autodiscoveryParams = {
    enableIMAPAutodiscovery = yes
    enablePOP3Autodiscovery = no
    enableSMTPAutodiscovery = yes
    enableWebDavAutodiscovery = yes
    autodiscoveryDefaultUrls = {
        httpAutodiscoveryUrl = ""
        imapAutodiscoveryUrl = "imaps://example.com:993"
        pop3AutodiscoveryUrl = "pop3s://example.com:995"
        smtpAutodiscoveryUrl = "smtps://example.com:465"
        webDavAutodiscoveryUrl = ""
    }
}

 

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

autodiscover          IN      A       193.230.245.23

If you perform a custom configuration:

  • enableIMAPAutodiscovery = yes
  • enablePOP3Autodiscovery = yes
  • enableSMTPAutodiscovery = yes

eM Client will automatically choose IMAP over POP3.
