You'd need to use a full rule, as body and rawbody won't be able to see the mime
section headers.
You'll want to have the rule target headers like this:
Content-Disposition: attachment; filename="EVI-Attachment-Warning.txt"
Sometimes, these headers wrap like this one:
Content-Disposition: attachment;
filename="00_non_deliverable.cf"
A full rule won't cover the linewrap, so you need to include an optional \s or .
after the attachment part.
So something like this should work:
full L_FOO_BAR /Content-Disposition: attachment;.{0,30}
filename=.{0,50}\.foo\.bar/i
Some files can have an inline disposition, but I doubt your in-house extension
does. That's usually used for text, html and/or graphics that a mail client can
render.
