It's on my list. “Compliant” is probably a strong word. It's 
probably going to be more like a “workaround”. The solution is 
likely to be what I believe is called From munging. Luckily, I control 
the email client used by most users of this list which means that this 
might also be an opportunity to improve MailMate behavior when faced 
with munged From headers :)

Thanks! At least you'll know that all list members will get your emails
