So how can I redirect any connections to port 25 from a specific ip address to connect to another ip address. Basically I would like to redirect all the connections back to the spammers machine if possible. Is this possible, or could this cause more problems.
I'm going to add my voice to everyone who says just block port 25!
I feel pretty sure that you get your mail by POP3 from NT Hell World's server, so you don't need to allow port 25 from the outside world.
Yes, if you are using pop3 to get your email then you ABSOLUTELY need to block incoming access to port 25. If your using sendmail, postfix or whatever to send email then just use the default SuSE configs for this which have it listen only on localhost. Please don't contribute to open relays. :)
I regularly run the mail relay test yo ensure its not acting as a relay. I though I was using the default SuSE configs and that caused the problem with the machine acting as a mail relay for similar ip addresses. mynetworks needs to be defined in the config file to be certain. I own a few domains, so all the email for these domains goes direct to my machine and not via NTL. One reason is that there servers aren't that reliable.
