Good luck with spammers trying abuse that. A naive filter wouldn't
know at all about l= but are well acquainted with spammers inserting
good looking text with spammy text. A dkim aware filter would be even
less impressed as the unsigned content would stick out like a sore
thumb. For all of the hysterical warnings in the spec, it would be
nice to hear about even ONE successful abuse. It's been, what, 5
years now?
