Oh no. What a wicked world you have welcomed me to!

You are talking about client-side filters though right? Most of
our users do not know how to create filters. I would much
rather stop this stuff before it ever gets delivered. Have you got
a sample filter I could use to dump this stuff at SMTP time?

And I'm still curious as to how "mensa.uleth.ca" gets added.
If exim itself is tacking this on, how can I stop it from doing that?
And what did the message look like before mensa.uleth.ca was
added to it? Just a local part with no domain?

I apologize for my naivete. I am currently working my way through
the exim manual. Lots to learn, and very interesting reading, but
I haven't mastered all of it yet (I would say I have mastered about
40% of it so far, which is why example filters (if you have any)
come in handy. TIA.
