Hi

Thats the problem. I can't find anything wrong with the DNS entries.

we are trying to send from library.wits.ac.za, but If I send form my pc I
get the same response as shown by logs

I have no problem sending anywhere else. Also if I change my outgoing mail
server to another server (running exim4.10 ) it works as shown below.

2003-11-13 11:13:44 1AKHI8-0002oi-00 Completed
