Ah, the % hack. A message addressed as follows will allow a relay:
Joeblow%remotedomain.moc@xxxxxxxxxxxxxxx
<mailto:Joeblow%25remotedomain.moc@xxxxxxxxxxxxxxx> , where your server
answers for localdomain.moc, when it recives a message addressed as shown,
it will turn around and deliver it to joeblow@xxxxxxxxxxxxxxxx
<mailto:joeblow@xxxxxxxxxxxxxxxx> .
IMHO, some of this has to be blamed on Netscape, as the % function is there
to be compatable with their software. But in doing so, allows for relaying.
The spam software I use (not on an Exchange box) has a specific test for
this. I am not sure how to protect against this on Exchange.
