HTML Image Spam

Any good way of blocking HTML images? I have Fuzzy Ocr, and when I copy this
message and send the picture directly in the message, Fuzzy OCR picks it up.
What they're doing is using an <img src> tag to show the picture with the
Viagra/cialis pills which is on a remote website instead of attaching or
putting the image directly in the message.

It's all at t35.com
valrietaolheqs.t35.com that's where they want you to go.

The picture is stored on:

What's the hostname in the img src URI? Does it hit any URIBL?

Or, maybe -- let me put it this way. By reviewing spam, I've probably
come across more expressions for "penis" in English, than I ever will
know in German, my mother tongue.

If you try hard enough to circumvent a filter, you ultimately /can/
succeed -- temporarily.

Is that really singular!?  So he got a single spam slip through? If he's
making a really big fuzz out of that, tell him to get a life.

True. As long as we're after the bad boys. Same with the police. They
can resolve a crime, they can't always prevent it.

Or...you could turn off spam filtering for this user to show him just 
how much spam he's NOT getting.

If he wants to get absolutely no spam that is very very easy.  
Disconnect the Ethernet cord.

Short of that, he WILL get spam. SA is good, it's not that good.  
Nothing is.

Well my client doesn't load images, and I already check against the zen rbl.
The guy who got the message is making a big stink about the fact that he got
the message. I figured there's really not that much that can be done.

Run a mail client that doesn't load images from remote servers?

Check incoming mail against the zen rbl.

Both of these will help.
