 * Have Mailbank changed it’s way of authentication in the latest release?
 * I’m getting: 504 5.7.4 Unrecognized authentication type from my Microsoft ESMTP
   MAIL Service.
 * Obviously because Microsoft ESMTP isn’t supporting AUTH PLAIN, is there a way
   around this? I think Microsoft ESMTP server requires AUTH NTLM or AUTH LOGIN 
   when using TLS

 * Hi!
 * For me, there was no need to downgrade to an older version, upgrading to 2.0.2
   solved the problem, also I just updated to 2.0.4 and it still works.
