I posed this question to Philip directly and he asked that I bring it up on
the list for discussion. Currently Received: headers are written after the
headers are received. I'd like to see that changed to them being written
after the body is received.
Given the following Received headers:
Received: from central.example.com ([10.0.0.1]:35689)
by mercury.example.net with esmtp (Exim 4.14)
id 1AzA5G-0000VF-6d
for mysqlnotify@???; Fri, 05 Mar 2004 01:49:26 -0500
Received: from mysql by central.example.com with local-bsmtp (Exim 4.23)
id 1Az5ZB-0005UO-IJ
for mysqlnotify@???; Thu, 04 Mar 2004 22:00:01 -0500
you'd think that the message was submitted to the queue on central
at 22:00:01 and then sat on queue for close to 4 hrs before being delivered
to mercury. However that was not the case. It was a script that started at
22:00 and slowly wrote data to the BSMTP pipe over the next 4 hrs.
Arguably, the way things are now give an inaccurate portrayal of the message's
lifetime on the queue. I also think that that having them written before the
entire message is received is counter-intuitive.
Also in this case it would lead an admin who was looking for info on
1Az5ZB-0005UO-IJ in the logs given those Received headers to look in the
wrong place since the entry for 1Az5ZB-0005UO-IJ does not appear in the
Thursday logfiles as the headers suggest it should:
37 [central][10:02am][mysql]# grep 1Az5ZB-0005UO-IJ /var/log/exim/mainlog.01
38 [central][11:48am][mysql]# grep 1Az5ZB-0005UO-IJ /var/log/exim/mainlog
2004-03-05 01:48:52 1Az5ZB-0005UO-IJ <= mysql@??? U=mysql

Any comments?
Thanks,
Tabor
