YEAH, GREAT NOEL ! OF COURSE !

I'm banging my poor head against the walls.

Since there are 2 different services for receiving and sending (smtpd and smtp) that is why
the first doesn't solve anything and the other solves everything.

And since the faulty configuration is an amavisd one, the faulty line is a the end of the master.cf so when I compared
both master.cf I didn't see anything (at first sight) since the orignal smtpd line was commented on the faulty config (and except the # there was no difference).

Ok, Noel, you gave me the only right information : it's time for me to sleep now,

Best,
