I have been running my own e-mail server for a while, and I noticed that scanning for open relays has been on the rise during the last days. So I whipped up a little script that parses postfix logs, isolates "hostile" IP addresses, finds the ISP abuse contact and sends an appropriate e-mail to them with the relevant log entries. I just let them know (nicely) that one of their clients is likely up to no good.

So far, about 30 e-mails have been sent, but no one has bothered replying so far (not even to say "thanks, we'll look into it"). I end up wondering: is it really worth notifying providers? Is someone actually reading abuse mail? Does he/she want to know about possible spammers on his network?

I don't really care about my server being scanned, it's just that I feel like I should do something to make the spammer's job harder.

Thanks in advance for your input!

It depends on ISP approach of course. I have worked in the biggest Polish Web Hosting company. We always did some action in case of abuse. Of course we replied and did some actions targeted to spammer. If it's SPAM, you can report these addresses to an RBL list.
