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:

 

1 capability
* CAPABILITY IMAP4 IMAP4rev1
1 OK CAPABILITY completed

 

Thanks
