I recently changed our email system (NOTES) to send to a
relay host, Windows 2000 SMTP Server.  Ever since I did
that, we have been getting weird NDR's.  There is one
domain, if we send mail to, nissan-usa.com, that the email
goes through, but we get a NDR back with error code
Enhanced Mail System Status Code (RFC1893): 4.4.7.  I know
that is a NOTES error code, but the email is queued at the
Windows 2000 SMTP Server, and it sends it out.  But for
some reason, the SMTP server thinks the mail is non-
deliverable, and then bounces it back in to NOTES.  Any
ideas?

hi jeffrey,

have you tried to connect to the nissan SMTP server with telnet and deliver
a mail manually?

I tried the following:
--------------
nslookup -q=mx nissan-usa.com
....
nissan-usa.com  MX preference = 50, mail exchanger = relay.attens.com
nissan-usa.com  MX preference = 20, mail exchanger =
nmchqt24zz.nissan-usa.com
nissan-usa.com  MX preference = 30, mail exchanger =
ncene02zz.nissan-usa.com
nissan-usa.com  MX preference = 40, mail exchanger = smtp.nmac.com

nmchqt24zz.nissan-usa.com       internet address = 205.144.99.69
ncene02zz.nissan-usa.com        internet address = 209.64.87.74
smtp.nmac.com   internet address = 12.14.189.242
--------------

12.14.189.242, 209.64.87.74 and 205.144.99.69 are not responding on port 25
(down?)
relay.attens.com  is responding and accepts mails to nissan-usa.com, but its
the last one
in the MX priority listing.

I think that your SMTP server should try to connect to the alternate mail
exchangers according
to the priority list until it can deliver the mail - or finally give up.
according to your logfile, your
SMTP server tries to deliver the mail to nissan-usa.com via 209.64.87.74
which is definitely
not responing (at the moment).

do you have any entries for 63.240.1.41 (relay.attens.com) in your logfile?
would be
interesting if your SMTP server even tries to use this one to deliver the
mail....


regards,
andi

Yes, that IP is in the log, but same results.  one line
with 0, and the next with quit.

Jeffrey, can you setup (just to make sure you have no DNS issues) a remote
domain to forward all mail with an address space of 'nissan-usa.com' to a
smart host with IP 63.240.1.41?  Let us know if you get the mail going this
way.  I also verified that 63.240.1.41 is up and running and accepts mail
for nissan-usa.com (Andreas done very good analysis on it - thanks!)
