Hi,

These are a real concern. If you receive any kind of real mail volume,
you're receiving these too, and they're not always being caught by
RBLs or virus scanners. Or even our well-trained bayes.

I used to have some rules that would reliably block them, but they're

I'm posting this in hopes someone has some other ideas, as well as to
raise awareness about their existence.

Ideas greatly appreciated.

We need a PDF plugin that will extract text and URLs from PDF attachments so that they can be scanned as if they were body text.
