Well, you can try complaining to Sympatico, but they're a Very Big
Company and I doubt you'll get very far. Still, it's a bogus way to
configure an SMTP server, and they should fix it. It's probably a very
lame attempt to block spammers from using Sympatico.

You don't -- you specify the enveloper sender either directly in an SMTP
session ("MAIL FROM:<...>"), or with the -f option to Exim. Eg.
exim -f postmaster@??? < /dev/null
will send an empty message with an envelope sender of
"postmaster@???". Note that you need to be a "trusted user" to use
this option. RTFM on -f and the trusted_users directive.
