Topic: Help if possible.

The problem I am having is that Email works fine leaving iRedmail.  I have created a Virtual domain test.org  I have created a user rhawkins@test.org  I can email through our exchange server as a relay.  When I try to reply back I keep getting

'rhawkins@test.org' on 2/17/2010 10:18 AM
            The e-mail account does not exist at the organization this message was sent to.  Check the e-mail address, or contact the recipient directly to find out the correct address.

I have added lvmail and mx record in DNS and pmail as second mx record.

Thanks in advance!


Re: Help if possible.

Nevermind..  I figured it out..

On my exchange server I had to add a smtp connector and add an address space.
