>From the 1.0pre2i manual:
6.3.19. bounce_delivered
Type boolean
Default: set
When this variable is set, mutt will include Delivered-To headers
when bouncing messages. Postfix users may wish to unset this
variable.
Why unset for Postfix users?
My ISP uses Postfix (I use my ISP's mutt), and the headers on a bounced mail
are the same whether I set bounce_delivered or not. In both cases, four
"Resent: ___" headers are added, but there is no "Delivered-To:" header.
(Just trying to understand how the new variable works.)
