    Confusion in recipient verification/protocol preset

    blason

      Hey Guys,

       

      I am testing MEG in my testing environment and below is my setup

       

      192.168.5.153     mail.isn.net

      192.168.5.154      mx.isn.net

      192.168.5.155      DNS Server

      192.168.5.156     mail.test.net

       

      mail.isn.net is relaying mail to test.net using mx & mail.test.net is sending mail to mail.isn.net using MX lookup. Every appliance has DNS configured as 192.168.5.155 and proper record exists.

      Mail flow is perfectly fine until I start Recipient verification. I have setup LDAP query and wanted to block unknown emails or email harvesting. This i creating an issue as soon as I enable that setting and mail gets bounced with 550 error.

       

      Then I tweaked protocol presets as I came to know recipient verification applies globally and wanted to enable only for incoming mails. But somehow I am missing as mails from isn.net to test.net is continuously getting blocked. And when I disable the setting mail goes fine.

       

      Any clue what I am missing here?
