SA Bugzilla – Bug 1422
New spam trick: mail body is just gif/jpg/png image
Last modified: 2003-01-25 00:58:04 UTC
As soon as I get another one, I'll submit someplace/somehow. The mail message itself appears to make it thru spamassassin unmolested. The trick appears to lie in making the body entirely from a single or multiple gif images, presumably with a text/multipart mime setup in which the plaintext is innocuous enough, but the html representation contains nothing but img src tags which fetch spam images. Of course, a simple solution would be to not use an html enabled mail reader...but, I like mine. (netscape7) :) Will append message source next I get one.

This should be caught by rules already in 2.50.
closing as wontfix since it's already fixed. :)
