I've set up Dovecot to use my signed SSL certificate and IMAP client is using STARTTLS on port 143 without secure authentication.
The TLS negociation process seems to go through ok but once the negociation is finished the client sends an IMAP LOGOUT message; he does not try to authenticate, below is the Dovecot's info log:
dovecot: 2010-06-15 15:37:01 Info: auth(default): new auth connection: pid=3932 dovecot: 2010-06-15 15:37:03 Info: imap-login: Aborted login (0 authentication attempts): rip=130.100.32.54, lip=10.0.3.3, TLS
I've decrypted the TLS negociation thanks to Wireshark (in SSL preferences I added the certificate's private key to decode the stream between client and server) but unfortunately it does not say why the client is sending the LOGOUT command.
Do you have an idea of what could be wrong in my server set up? What debugging process would you advise me to follow?
What client are you using? Have you tried other clients to see if they do the same LOGOUT?
