Hi there,
I have a lotus notes SMTP server. It has been configured NOT to relay mail. If an attempt is made to relay mail through this server then this is noted in the notes log.
Sure enough from time to time I do see a relay message being denied, but not very often.
Recently I install a product(on a different server to my notes SMTP server) from Network Associates called "SMTP Webshield". It adds an extra level of SMTP protection to the antivirus software I already have installed on my SMTP server(Groupshield). Webshield allows me to stop all sorts of mail reaching my users based on a varity of options(Source domain, Mail subject, the ususal stuff). Because of what it does Webshield has an SMTP engine.
I installed this product and basically played with it.After a couple of hours I checked the stats on this product. Every second Webshield was relaying mail for many different sources! I know that I can stop this using the config options provided.
However my question is this. How did these spammers get a hold of my server. Who told them the IP address.
As I said at the beginning of my mail, when my notes SMTP server does get someone trying to use it for spamming it is noted notes log. But these attempts are very very few and far between.
Was I just unlucky that someone got a hold of my Webshield server before I configured it NOT to relay. Am I being very naive in this cruel world of Spam?
Thanks for any help,
