Dovecot (Changed default ports & attempted to setup SSL Only) and dovecot is running... roundcube doesn't work and cant connect with thunderbird.

I went into the Dovecot Module on the Webmin Side under Servers, and went through the configuration files and changed the ports to non standard. And then allowing them in CSF Firewall.

  • Roundcube stopped working (looked in the front-end configuration and didn't find settings to change.) is there a backend configuration for roundcube and dovecot?

  • Help using SSL only w/ SSL CA Cert with all non SSL disabled.

Thank you kindly!

Howdy -- you may want to temporarily stop your firewall, and see if you're able to connect at that point.

That would determine whether it's an issue with the firewall, or whether we need to be looking at the Dovecot or email client configuration.

How about roundcube? How do I edit the backend configuration, for ports and such?

Regarding the actual DoveCot configuration:

The webmin configuration says the following in :

/etc/dovecot/dovecot.conf

Protocols we want to be serving. protocols = imap pop3 lmtp

protocols = imap pop3 lmtp

I added a DNS entry for SMTP ... where do I setup the SMTP port? I changed all the rest, lmap, pop3 and lmtp.

Thanks again.

SMTP is configured within the Postfix email server.

I'd recommend not changing that though, as keeping the same SMTP port is necessary for other email servers to communicate with you.

If the SMTP port is changed, no server on the Internet will be able to send you an email.
