The view from up here is amazing

It's truly incredible what you can see when you look down from the heights of idiocy -- the vistas are breathtaking.

Right now I'm looking at a wad of virus-generated mail bounced back to me because it failed an SPF check at the receiver's end.

Yep, that's right. Someone configured their mail server to check and see if inbound mail had a forged From address and, if it found that it was, bounce it back. Back to the forged from. You know, the one you just checked and found thatit didn't come from.

Some days people truly puzzle me.

Yeah. Like, duh. Sigh. Maybe we should all just move to IM2000 over RSS...

Tin cans and string. I think that's about the best we seem to be able to collectively manage.... :(

At least it's only one site doing this, so the ineptitude's limited. For now, at least.

What else can you do with it? Ideally you'd reject it within the SMTP transaction. But what if you discover the problem later? It might be just an error in the SPF record or in which SMTP server they use, and it's better to let them know than to make it disappear into the void.

I find these things frustrating, too; I get a lot of worm fallout. But it's hard to solve until you understand why it happens.

By the way, this is at the bottom of my comment preview:
