Overnight I've received a bunch of bounced email messages suggesting that somebody is spamming from my email address.

How are they doing it? And how do I stop them?

You need to look at the full headers to see the originating IP...

Attached are a couple of typical bounced spam messages. They don't seem to have anything in common.

Anyone can spoof another's address by putting it in the 'from' header, either in a script or mailer app. Using a simple PHP script like this would work:

mail($to, $subject, $message, 'From:throb@bumpoke.com');

TBH, I don't think you can, they're probably not routing via your (host's) server.

If it's just spoofing then I'm irritated but not too arsed. It was the thought that it might have been through my domain mail via a keylogger or summat thast was worrying me. I am running a zillion antimalware progs as I type, all of which will probably accuse each other of badness.

shit shit shit.... :(

Yeah, you won't be able to do much about that... Wot MrB said above, you can pretend to have any email address when you send an email if the server accepts it, so why they picked yours is irrelevant. The initial source IP is different, so it's most likely a botnet that's using your email as a random source. I don't really understand why they use real source addresses tbh...

Obviously trading on my internationally renowned good name.

As long as it's just spoofed I'm not too fussed. My escutcheon may have been blotted in the block list of some Russian spambuster nannyware, but I can live with that.

If you have an email address visible online then chances are it will happen. I was once worried it may end up with my address black listed but apparently the black listing people are smarter than that!

Is that the listing people who is black?

It's like the opposite of being on that BNP membership list that was leaked.

Keighley featured prominently as a home address in that list. Bit depressing.

I was surprised at how many edinburgers were on it, from the posh parts of town :S

Mel Gibson?

He's not an edinburger, he's Irish in't he?

You're thinking of Russell Crowe.

Quite frequently, but I thought he was a greek.

You're thinking of Anthony Quinn.

He's an Aye-rab.

You're thinking of Peter o'Toole.
