Our E2K mailbox servers have recently developed a bad habit...
Many people here (myself included) create Outlook rules to move their
Internet email into a separate folder based on the SMTP headers. A couple of
days ago this stopped working. An quick examination of an incoming Internet
email's headers showed that most all of the header information was gone, and
what was there is strange.
Our email flow is this:
1. Internet to Cleanmail (floyd.cinergycom.net) (for virus scrubbing)
2. Cleanmail to our checkpoint firewall (kimbintinc-cp.kimball.com)
3. Checkpoint to nts126 (a NT4/MSX5.5 IMS connector) 4. nts126 to nts390
(E2K mailbox) via MTA
Normally, Internet email "Received:" headers look like this (edited for
brevity):
Received: from kimbintinc-cp.kimball.com (igate.kimball.com
[167.178.249.18]) by nts126.kimball.com ...
Received: (6577 bytes) by floyd.cinergycom.net
Received: by cleanmail.com ...
Received: from csc222.csc.dg.com(xn82.emc.com[168.159.1.82]) (6103 bytes) by
floyd.cinergycom.net
Notice that nts390 is NOT listed in the headers, since nts126 (an MSX5.5 IMS
server) sends email to nts390 (E2K mailbox server) via MTA, not SMTP.
However, recently, This is what I see when looking at headers:
Microsoft Mail Internet Headers Version 2.0
Received: by nts390.kii.kimball.com
id <[EMAIL PROTECTED]>; Mon, 18 Nov 2002
09:03:08 -0500
There are several things wrong with this picture:
1. All of the preceding (timewise) "Received:" headers are gone.
2. Internet mail cannot be going directly to nts390, it must be going
through nts126
3. The one "Received:" header does not show who the message was received
from.
A reboot of the E2K mailbox server fixes the problem for a while, then it
mysteriously comes back.
Any ideas?
