Good idea, I plan to install a Fedora this week-end and to learn a bit
about Postfix. Your wide experience will certainly help.

If you think that sendmail or postfix modify the "enveloppe from" when

MARID working group, where it may change a lot of things in the
current discussion about Sender-ID :-)
