Our domain is sun.ac.za
We relay email for a few other domains including prg.wcape.school.za.
A user with the address estelle@??? complains that email
sent to her from outside does not reach her.
An example was an email she sent to herself from a yahoo account - at
test message CC'd to me.
When I opened the email, the headers looked like this:
==================

==============================
However in the mainlog on mail2.sun.ac.za I found this:
=================
2007-01-26 15:03:15 1HAQjX-0001xZ-UO <= melissa_langley555@??? H=web28014.mail.ukl.yahoo.com [217.146.182.119] P=smtp S=2902 id=20070126130241.90985.qmail@???

2007-01-26 15:03:15 1HAQjX-0001xY-U0 Completed
=================
I then ran 'exim4 -d-all+acl+rewrite+route -bhc 217.146.182.119' using
"mail from: melissa_langley555@???" and "rcpt to:
estelle@???" and the output showed that it would be
deliverd to prg.wcape.schoo.za as it is supposed to be.
Now my question. If the log shows that the message was addressed to
estelle@??? <estelle@???> while the "To:"-field
in the message showed estelle@???, how could this
happen?
If it is a configuration error on our server, how can I determine where
what went wrong? Several -bh tests revealed nothing.
Regards
Johann
