If I try to connect instead via the imaps port (993), the attempt times out and I get the following in the log: imaps[27170]: imaps TLS negotiation failed: [xx.xx.xx.xx] imaps[27170]: Fatal error: tls_start_servertls() failed Any ideas?Try the command line openssl client and see if it can negotiate SSL/TLS. Something like this: openssl s_client -connect your_server_dns_name:993 -CApath /etc/ssl/certs CApath should be the path to your local CA certificates directory, /etc/ssl/certs on Debian Linux. You could also add -debug to get a hex dump of the traffic. Can you post your imapd.conf file (sanitized)?
Just for reference, the above error happens when you try STARTTLS on port 993:
# telnet student.ednet.ns.ca 993 Trying 142.227.51.32... Connected to student.ednet.ns.ca. Escape character is '^]'. starttls * BYE Fatal error: tls_start_servertls() failed Connection closed by foreign host.
