I am using IMAP with Dovecot. Claws-mail is my MUA. Now, when fetching
mail via port 143, everything works fine:
Mar 29 10:33:00 imap-login: Info: Login: user=user@domain.net, method=CRAM-MD5, rip=127.0.0.1, lip=127.0.0.1, TLS
However, when I attempt to fetch mail via port 993, I get this message
in the log:
Mar 29 10:28:35 imap-login: Info: Disconnected (no auth attempts): rip=127.0.0.1, lip=127.0.0.1, TLS handshaking: Disconnected
Try connecting like this:
openssl s_client -connect 127.0.0.1:993
If it connects OK, then try sending some IMAP commands:
a login user@domain.net yourpassword
a examine inbox
a logout
If that's OK, then your MUA may have disconnected without sending anything.
Perhaps it rejected your certificate? Or your MUA might be trying to connect
using non-SSL IMAP on port 993? Maybe it only supports STARTTLS for SSL,
in which case you'd use this on port 143.
HTH,
