I have an SBS 2008 server that is running Exchange 2007. Everything is up to date but for some reason the info@ email address will receive mail. I originally had it as a distribution group until I learned that it was not accepting email. Users would get a bounce back message saying there is no route and the recipient cannot be found on the server.
I went ahead and deleted the distribution group and added the alias to an existing mailbox, and got the same results. I then went ahead and created an alias called email@example.com and it worked perfectly fine. I cannot figure out why it will not accept firstname.lastname@example.org email. Everything else works perfectly fine. Below is the bounce back message we're getting.
Desperate to get this fixed.
