Imap telnet
How to test an IMAP server using telnet
Encryption
As the port-number normally is 993, an example OpenSSL command would be openssl s_client -connect imap.example.com:993 -quiet. (If you would like to see the public key of the server, as well as some other encryption-related information, omit -quiet.) The server should then start an IMAP session, displaying a greeting such as the * OK Dovecot ready example below.
telnet: > telnet imap.example.com imap telnet: Trying 192.0.2.2... telnet: Connected to imap.example.com. telnet: Escape character is '^]'. server: * OK Dovecot ready. client: a1 LOGIN MyUsername MyPassword server: a1 OK Logged in. client: a2 LIST "" "*" server: * LIST (\HasNoChildren) "."
