I had a quick look around on the parallels forums and others to find a solution. The solution for the problem appears to be "disable mail service for this domain" The issue is a client is sending emails to 8 external clients and getting the following bounce back: None of the domain sending the email to exist on our server so I'm wondering what the issue could be? I checked that the sender exists and that their account was enabled which it was... Any advise? Thanks
