If it is related to your system's MTU size, I'll eat my normal head
covering.

Several answers in the FAQ answer your question:

'trusted users' in most MTAs refers to the users that are allowed to set
the 'From' or 'Sender' address to something other than that username.
Unless exim has changed some stuff recently, I don't think it refers to
users allowed to do special things when receiving mail.

Have you tried running rt-mailgate as the user exim tries to run it as?
This should be in group 'rt'.
