Hello,
the error is still present: May 8 19:47:18 opsys dovecot: imap-login: Disconnected (no auth attempts): rip=82.113.119.140, lip=78.46.216.126
Whenever I start a session with openssl to STARTTTL (Server: mail.opsys.de) the handshake is successfull. Also I am able to login to my account via 1 login. In Thunderbird port 993 for SSL/TLS works correct, only STARTTLS on port 143 isn't working properly. The cert is Class 1 and signed by StartCom Ltd.. Dovecot.conf (for viewable reasons of this mail pasted): http://pastie.org/private/bmrymyuo16ohzxdahf0nq And here openssl output: http://pastie.org/private/3rpgll2s7hblev9ozpcq8w Note the 'Verify return code: 21 (unable to verify the first certificate)' in the output...
Thanks for helping, I am working on this problem since 3 days.
Kind regards
Markus Fritz
