I cannot send encrypted mails with postfix / dovecot.

I regenerated the certificate, it seems alright. Checking it with openssl returns RSA KEY OK. However, I still face the same issue.

from /var/log/maillog:

warning: TLS library problem: 11390:error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol:s23_srvr.c:640

Connecting with IMAP:

Unable to negotiate TLS

Sending via SMTP:

Must issue a STARTTLS command first

TLS over telnet works:

220 2.0.0 Ready to start TLS

I need you to tell me either where the problem lies, or, if really necessary, work via teamviewer in my putty. I'd prefer working here on freelancer tho.

I am also looking for a server admin on an ongoing basis.

Skills: Apache, Debian, Nginx, Plesk, VMware
