    Hello GAZ,

    Do you have an SMTP connector setup for outgoing mail? If so the settings
    on the connector override the SMTPVS and the connector can be setup to
    allow open relay.
    On the Address space tab of your connector make sure the "Allow Messages to
    be Relayed to these Domains" is not checked. If this is checked and you
    have a * address space you will be open relay.

Hello everyone,
I would be most grateful if you could help me with a 'small' relaying 
problem.
We have the Exchange 2000 enterprise server with the SMTP virtual server 
behind the ISA 2000 firewall.
Basically, several days ago we 'started' relaying messages all over the 
shop. The Relay tab is set to 'Only listed below' with nothing in the list 
and the 'Allow all computers...' is unchecked. However, spam still passes 
through. We started putting whole ranges of IP address in the banned list 
on 
the connection tab. The problem is that the spammers change ip addresses 
constantly and we have to extend the list almost on a daily basis. Never 
mind the bandwidth gone to waste, but we definitely do not want to end up 
on 
a black list.
Is there a one time 'kill all' solution that would prevent spammers from 
using our server?
Thank you all for you help,
GAZ
