[cobalt-users] Stopping SPAM Relaying via My Mail Server?

[Hamish Mackellar <hamish@xxxxxxxxxxx>]

Hi everyone,
Thanks for a great tool via the cobalt user list.

I have noticed of late, a huge number of unwelcome email going from our 
mail server with reply addresses that dont exsist.  I am guessing that 
a SPAMER is using our mail server to relay their mail?  Is that 
correct? And any ideas on how to stop it?

Thanks for you help.
Hamish.

Kind Regards
