I'm afraid you cannot. Exim runs as "exim" when talking to remote hosts,
when configured as recommended with its own uid. All I can suggest is
that you somehow provide a setuid wrapper for PAM, but I don't know how
this could be done.

By re-execing itself. It only needs to do this to start a delivery
process after receiving a message.
