Ah, good, I hoped you had but wanted to make 100% sure as it's easy to get bitten. I've also been bitten by a couple of spammers using one of my domains as a From: address... then I get 300 bounce messages in a day. Hasn't happened for a while though (fingers crossed), I guess most sensible admins have now set their systems to black-hole invalid addresses. > It's not a problem for me, except that Ann's provider is too dumb to > recognise that the From: address is not related to the actual sending domain > so they've blocked the domain on the From: address.

A provider should never use one single parameter to judge an email as spam. Do you have an SPF record set up? That might help in some cases but it's really a long shot. Unfortunately you don't hold much sway over providers unless you're the size of ebay. Heck, even our own spam filter at work tends to delay or block emails that I send myself when testing web apps. Personally I think the whole email system needs to be redesigned from the ground up. But I don't want to be the poor sucker who gets to do it as no matter what you do you'll break some legacy system somewhere.
