The posts from the remail service, dizum.com and the idiot may be able to be stopped. They provide a DESTINATION-BLOCK service which will block your email address from anyone sending you spam via their service.
If someone knows how to munge their email address so it say's rec.woodworking this may work.
Send the email to snipped-for-privacy@dizum.com
enter the words in the body of the message.... DESTINATION-BLOCK and it will enter the header address it was sent from and block that address. You can also block whole domains according to their blocking policy.
Not sure if the above will work but worth a shot if some guru out there knows how to do it.
