No longer connecting to dovecot IMAPS 993

    Hi all,

    This weekend, one of my mail servers stopped accepting connections from mail clients for IMAPS using port 993. I'm testing using Evolution and Outlook. I can connect via TLS still using port 143. Also, POP3S still works fine on port 995. The server had been working without issue for nearly a year now, and no changes were made that would help explain this behavior.

    Looking at netstat, I see that a connection is registered:

    tcp 0 0 ESTABLISHED 6697/imap-login keepalive (7166.64/0/0)

    However, I see no info in mail.log acknowledging this connection.

    Also, I can connect and authenticate fine using the following:

    openssl s_client -connect

    Any further information that would be helpful? Anyone ever run into a similar problem or have any thoughts?

    Thanks much!

    Further testing, I can connect from Evolution and Outlook using SSL, but not TLS.
