Oh they have, just as they defeat any other method of SPAM detection 
eventually.  Its just that it's so simple to add a rule to TMDA over the 
process of SPAM filtering.

One way that has now been resolved was to set the RETURN-PATH header to the 
same as the delivery address.  TMDA accepted it as coming from the 
destination and let it through.

That's been resolved.

Image Spam isn't so easy to "block" using other spam filter systems, 
however, TMDA doesn't care about content of the message, it cares about the 
sender and the recipient.

Link is white listed.  Actually my link@ address was originally set to 
bypass my TMDA account altogether and was sent to a second mailbox account 
on my server.  However because of the harvesting of addresses from the LINK 
archives and mail list itself, I had to switch it to the quarantine account :(

And Mailman messages sent from link are not caught by the quarantine 
process.  Otherwise I'd never get a link posting!
