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 server.com:imaps client.com:57904 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 server.com:993 Any further information that would be helpful? Anyone ever run into a similar problem or have any thoughts? Thanks much!
