Postfix and amavisd-new

[Olivier Nicole]

Hi,

I am making undue gray hairs on a problem between Postfix and
amavisd-new.

I have a setting on FreeBSD that is working like a charm, when I send
myself a message , Postfix authenticates me, receives the message and
pass it to amavis on the port that set originating (the messages
originating from mynetwork, for outgoing messages), so that the message
will receive DKIM stamp.

The headers look like:

DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/simple; d=cs.ait.ac.th; h=
	content-transfer-encoding:content-type:content-type:subject
	: blah blah

I am trying to replicate the same setting on a Debian machine and cannot
get it to work: after Postfix has authenticated the sender, the message
is pased to amavisd-nre on port 10024 (the port used for incoming
messages).

Headers are like;

Received: from mail.bknix.co.th ([127.0.0.1])
	by localhost (mail.bknix.co.th [127.0.0.1]) (amavisd-new, port 10024)

Message-ID: <54632D77.60501 at bknix.co.th>

I must be making a very stupid mistake, but I cannot get enough global
view of the problem to solve it, so any idea or pointer is most welcome.

Best regards, and TIA,

Olivier
