Please check your firewall settings, I am pretty sure that your case (which has a different root cause for the problem at hand, compared to the case of @ToniSoftware) is related to the VPS config and/or hosting provider default config ..... so try to determine what actually happens when using a local and an external connection to (on the one hand) smtp/smtps and on (the other hand) pop3/pop3s/imap/imaps: if that all works fine, then check the full roundcube config.
Essentially, the process above is a step-by-step analysis:
1 - check smtp and smtps connections: use for example telnet from a local and external machine.......if this works, no firewall issues and no postfix issues
2 - check pop3, pop3s, imap and imaps connections: if this works, no firewall issues and no dovecot or courier issues
3 - if either step 1 or 2 does not work: repair it and retry steps 1 and 2
4 - if steps 1 and 2 do work, but the issue still persists: then you are likely to have a broken roundcube config/setup (read: re-install roundcube)
Hope the above helps a bit.......regards!
Hi!!
My Firewall is ok.
I migrated the courier to dovecot. The problem persisted.
So I reinstalled Postfix. And the miracle happened!
The roundcube is sending emails normally.
Thanks to all for your help.
