IMAP with TLS will result in IMAP traffic crossing the network unencrypted, initially at least. Please note: If you try to establish a connection to port 993 from an non SSL client such as Telnet, the connection will fail. Point to the IMAP server over secure port 993. At this point, modify your mail client configuration to IMAPS (IMAP over SSL) means that IMAP traffic travel over a secure socket to a secure port, typically TCP port 993.Īssuming an SSL certificate is in place, there shouldn’t be anything further that needs to be enabled on the server.
