Does Smartermail support the AUTHENTICATE PLAIN login method? If so, how is it enabled? When we try the server responds with NO AUTHENTICATE instead of sending the expected '+' response (telling us to send the login command).
1 AUTHENTICATE PLAIN
* OK IMAP4rev1 SmarterMail
1 NO AUTHENTICATE
unexpected LOGIN response: 1 NO AUTHENTICATE
I can't tell if Smartermail supports AUTH PLAIN because it doesn't list its capabilities n response to the CAPABILITY command:
* CAPABILITY IMAP4 IMAP4rev1
1 OK CAPABILITY completed
