Weird email issue with Outlook

I am seeing something weird with email when the user is using a newer
version of outlook. The issue is this…

Instead of RT emails saying From User via RT XXX I am getting this now.

rt@XXXX.com; on behalf of; systems@XXXX.com mailto:systems@XXXX.com

This is a weird issue and only occurs on Outlook. Anyone had any experience
with this? The reply to line is fine but the from line just comes in funny.
I’ve tried turning off user friendly from lines and still no luck.

It would be better if you send small test message from Outlook, and send
us copy of this letter(with MIME headers) in attachment. It would be
better if you get this copy on RT server.

Lookout! is being “friendly” and showing the SMTP sender envelope
address as the sender. As a nice side effect, all mailing list mail
these people view also look like that, with the bounce address as the
from and “on behalf of” the real author. You’d think M$ would
actually try to do the right thing, but then you’d probably expect too
much.

There’s nothing you can do about it on the sending side, since it is
entirely a dain-bramaged display issue.

You can do something about it on the sending side - don’t include a
Sender: header. But yes, it’s totally stupid for any mail user agent
to actually do something with that header.
