What is your server and IP address?

 

If it is mail.durdans.com, you are fine.

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@xxxxxxxxxxxxxxxxx 

 

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.
