[H-GEN] I hate SPAM

[Michael Anthon]

I know this may be a little off topic, and I don't really want to start
any OS/Mailer wars, BUT.....

I have become a victim of a SPAM attack (ie, someone using my server to
relay SPAM) at work.  I am running MS Exchange Server and have not yet
figured out how to prevent it from being used for relaying.  I have now
blocked that particular domain, but that will not stop it from happening
again from another domain.

Now, I am looking at getting (sensible please) suggestions for
solutions.  I can see the following possibilities...

1. Configure MS Exchange Server to prevent relaying, if this is at all
possible.  Does anyone else have to work with this monstrosity??

2. Use one on my IPCs to run a decent mailer and set this to be the
primary destination and configure it to prevent relaying.  Then forward
any mail for my domain to the MS Server. I have enough real IPs to do
this and it's a simple matter to change the DNS entry.  I tend to favour
this solution, but it will probably take me a little while to configure
it.
