Hello all,
An argument issued with a colleague of mine when I said "myorigin happens
on the way in, while the canonical map is applied on the way out", or
something like that. My colleague insists myorigin happens on the way
out.None of us read the code, of course, we are both guessing. would you
guys care settling our difference? :)

Which process, in the Postfix system, uses myorigin, and would that be
called "on the way in", in the lifetime of an email inside Postfix? and same
for the canonical maps, which process applies them and would that be "on the
way out"?

Thanks a lot.
Mohamed.
