Ticket Content Blank When Request is Aliased

Odd problem here with RT3, not sure why it’s happening… might have
missed something obvious.

I have an alias to the rt-mailgate program setup on our websever, when I
send directly to the alias to the mailgate (ie
support@strider.csolve.net) the ticket creation works like a charm as

However, if I send to an alias that directs to
support@strider.csolve.net, the ticket gets created but the body of the
ticket is completely blank. I’m not sure why that is happening.

Any suggestions on what might be causing this?
