Barbara M.:
There is a settings/parameter that fix the date/time of a mail to the time
I start to compose it or when I sent it?
I noticied some differences after update of a server from 2.2 to 2.6.
Postfix 2.2 cron Job give this mail:
---------
Date: Mon, 2 Jan 2012 04:20:50
From: Cron Daemon <root@mail>
To: root@mail
Subject: Cron <root@mail> /etc/SCRIPTS/Backup
I.e. the time when mail submission completed.
Postfix 2.6 cron Job give this mail:
----------
Date: Sun, 15 Jan 2012 03:47:01
From: Cron Daemon <root@mail>

I.e. the time when mail submission started.
You can find the "submission completed" time in Received: message
headers, if you really need that.
Postfix 2.2 mail submission programs did not store any information,
so the rest of Postfix had to guess, by using the queue file
modification time. That was clumsy.
This was changed in Postfix 2.3, six years ago. It's a bit late to
complain about that.
In my limited kowledge of Postfix, I supposed something similar and
checked other servers for confirm or hints.
In another box that use the same version (a Scientific Linux 6.1 with
postfix-2.6.6-2.2.el6_1.i686), I have a result very similar to the 2.2
version and this confuse my analisys ... ;-) ):

Inserted a "sleep 5m" in the script for test:

For "statistics":
I have the same result also on all the CentOS 5.x boxes (that use Postfix
2.3.3 so can be expected to in the "old way"), while in the Proxmox
servers (postfix_2.5.5-1.1+lenny1_amd64.deb), mail date/time is as you
said must be.
Also on a CentOS 6.2 (64bit) that use the same Postfix version of
Scientific Linux 6.1 mail date/time is as you said must be.
I am a bit confused ... ;-)
Thanks for interest.
