Hello,

We are switching to iRedMail for our main email server and during the testing, we found a small issue that prevents us from receiving email on the iRedMail system.

Our setup is the following:
Internet-------Email Filtering Gateway-------iRedMail server

The Email Filtering Gateway does a quick recipient address lookup to the iRedMail server using root@domain.com as the  MAIL FROM  which for some security reason, the iRedMail rejects the lookup since the account root@domain.com has not be authenticated and it is an account on iRedMail system. If the lookup is successful then the gateway delivers the message. however, it it fails (which is our case) the email is not delivered and returned with an error.

Is there a way to configure iRedMail to allow such recipient lookups coming from the email filtering gateway without having the need for the root@domain.com to authenticate?

Thanks,
Jose Villasenor
