I've read thru the O'Reilly Exim3 book a few times. I wanted to rewrite
all From and Reply-To headers only on mail that is sent out the smtp
transport to my dialup isp. However, exim3 doesn't let you rewrite
envelope addresses on per-transport rewrites. The only other option
is to use the rewrite rule in the "generic" section of exim.conf.
This applies the rule to every local message floating around the system,
so its effects are too undefined for my liking.

Does exim4 allow envelope rewriting on only an smtp outgoing
mail transport?
