I don't want to get bogged down in details.
My point is that something that worked Monday, doesn't today. It is
unfortunate that several of the PC clients don't follow spec.

But Outlook & Mozilla are pretty common on campus, I would hope the mail
team would at least consider the Exim router patch. It is quite a
problem for faculty & staff to send to a large list of names, then get
the message refused because of a few bad addresses, but have no easy way
of determining which ones are the problem.

I did the telnet thing yesterday to find our 2 problem students (out of
130), so we are probably OK. And I see that using the webmail client
will identify the bad addresses. But Outlook always wants to hide the
actual addresses behind the given name, so a simple cut and paste into
the web client won't help.
