Some ideas I've had:
#1
Okay, so a bit unusual, but if you have a script in if-up.d that runs
nsupdate to update a local copy of bind, you'll always have a DNS name
that points to your nearest mail exchange
#2
Playing with DNS and search paths such that
smtp-forwarder.$any_domain_i_frequent exists, and using
"smtp-forwarder" as SMTP relayhost.
#3
Using deeper perl-foo in exim4, and doing like Peter suggests, but
consulting a file, that lists network masks and appropriate relay
hosts
lookup{ net-lsearch;$some_foo }{ CONFDIR/relay_by_domain }
