Actually, with the various Fedora MUAs I've used, it ended up being easier
to configure them to use local MTA as relay than to try to convince them
individually to do anything more complex than 'non-encrypted smtp without
auth' (when the options existed they changed every few MUA versions and I
got tired of re-parametring them all the time). Bonus point is that
changing the relay options fixes all MUAs in one go, I got free logging of
the MUA activity, and a send queue that does not depend on running the MUA
when the network comes back.

To be sure, it would be cleaner it the connexion user when relaying
depended on the system user that emitted the message. I've not checked if
it was possible or easy to do it.
