Hello,
I have this problem: May 5 21:02:35 opsys dovecot: imap-login: Disconnected (no auth attempts): rip=84.150.52.31, lip=78.46.216.126
Connecting via Thunderbird to STARTTLS won't work, but with a website from the same server it works for tls://opsys.de. So why is the port closed for external ip's? IPTABLES entry for imap is this: fail2ban-dovecot-pop3imap tcp -- anywhere anywhere multiport dports pop3,pop3s,imap2,imaps
Key files are correct TLS is working from localhost.
System is Debian squeeze
Thunderbird says 'tls not available due temporary reason' now.
Assuming your server cert is located in /etc/ssl/certs/ca-certificates.crt try this on your server:
openssl s_client -starttls imap -CAfile /etc/ssl/certs/ca-certificates.crt -connect localhost:143
Use "2 logout" to get out of the session.
If it works, try the same from your client host.
Does it work both times?
