153973 - Filter on body applies to base64 encoded image attachments

Status: VERIFIED DUPLICATE of bug 136055

(MailNews Core :: Filters, defect)

Description

[Tilo Christ]

Hello!

A harmless mail from my mom got filtered by my "Porn" spamfilter which searches
for all kinds of filthy words. I finally figured out that the base64
representation of the JPEG image she attached to the mail contained the
character sequence "anal", which triggered the filter. The filter was set to
delete mail where the body contains that word.
I think the filter should only apply to text messages/attachments (mimetype
text/*). BTW: I had a similar problem with an earlier version of Mozilla, where
the attachment boundary string contained the letters "XXX".

Sincerely,
Tilo Christ
