FW: AS/400 SMTP mail problems -- MIDRANGE-L

As a follow up to my previous posting I've become aware of something that may 
be of interest.
Petro-Canada recently changed all their e-mail set up and it's now being 
handled by IBM Global Services, as a small excerpt from the header info below 
shows:

Received: from petrocan.on.ca.ibm.net([129.37.152.8]) by DPS.DPSLINK.COM (IBM 
OS/400 SMTP V04R02M00) with TCP; Thu,  5 Nov 1998 09:05:38 -0500
Received: from pcaxs04.pccw.petro-canada.ca ([156.44.161.183]) by 
petrocan.on.ca.ibm.net (AIX4.2/UCB 8.7/8.7) with ESMTP id JAA29760 for 
<neilp@dpslink.com>; Thu, 5 Nov 1998 09:05:51 -0500 (EST)

THAT'S when the problem with the e-mail started for my customer using AS/400 
SMTP for e-mail.
Apparently IBM Global Network has a problem with receiving e-mail from AS/400's 
and they are "working on it" !!!!

Co-incidentally, the only other e-mail addresses I have seen this problem on 
(AS/400 SMTP routed mail) are with e-mail I had bounce back when sent to 
addresses "@ibm.net" (Hi Al !) - so I guess it's the same problem.

Hi Neil I have seen problems across all releases of SMTP on the AS/400
supporting the - in the domain name. I have one user in the IGNITe mailing
list that has a - in the domain and the system has problems sending to it
(V430), and I saw the same thing on a customers V370 and V410 machines.

Personally I think that SMTP has  several problems and this is just one of
them. It has issues with large loads being placed on it such as mailing
lists where several hundred connections are made and then crashing, lack of
support for multi-homing, it needs to be looked at again and the problems
fixed.

Thanks
Bleddyn
