Beset on all sides by spammers…

My consulting business has it’s own website and all that – it’s over at computerboy.com. It’s also got it’s own spam hi-jacker. Some nimrod has been sending out spam from a non-existant email address at my domain name – and since it’s spam, there’s a large number of messages that aren’t going through. Guess who gets those error messages? Me.
Dozens of them. And it’s really starting to irritate me. I’ve been filing abuse reports with the various upstream providers and dial-in owners (a whole two companies – this spammer isn’t that bright, apparently), but I know that won’t stop them from doing it.
At the same time, I’ve got a mail server in my basement that I use for my own testing and other nefarious purposes. I thought I had it locked down so it wasn’t just an open relay. I was wrong. I just got through reading over 100 bounce messages from that, and reports from several “watch dog” groups that have now black-listed that server. I don’t mind so much, since I don’t really use it for mail, but it’s irritating, and now I have to re-check everything to see where I went wrong, then have them re-check the server. Man does spam suck.
And you know what? It’s not “free” or no-cost. They send it out at the expense of others (i.e. you and me, who have to pay more for dialup and server fees so that the ISP’s can handle the load), then I have to waste what little free time I have during the day to try to get work done with dealing with it – meaning that I have to push back important projects with deadlines that I’m already close to missing.
Someone find me who did this. Or re-invent email so that it won’t happen anymore.
