Examples: [1] openssl s_client -connect mail.columbia.edu:993 [2] openssl s_client -connect mail.columbia.edu:143 -starttls imap [3] openssl s_client -connect mail.columbia.edu:993 -starttls imap
[1] and [2] should work ; [3] fails. The U Wash IMAP server gives the same results. These alternatives are commonly called "ssl" and "tls", but the actual distinction is whether the starttls command is used to get Transport Layer Security. First described in RFC 2595.
