Odd exchange 2003 problem
I've got a win2000 AD domain, one server has EX2003 installed (and service packed up).
DNS is installed on the exchange server & member servers configured in a round robin.
NSlookups work to external sites & caching is ok.
All is fine except sending to one domain:
spriproducts.com
As far as I can tell the problem is at our end (as yahoo.co.uk sends ok). There is nothing in the event log.
All that happens is we get a bounce (immediately):
Your message did not reach some or all of the intended recipients.
Subject: test
Sent: 19/12/2006 11:55
The following recipient(s) could not be reached:
'herb@spriproducts.com' on 19/12/2006 11:55
You do not have permission to send to this recipient. For assistance, contact your system administrator.
<mail.physicalcompany.co.uk #5.7.1 smtp;550 5.7.1 Message rejected.>
I really don't know why it's failing as we can send to other external domains fine. . .
Any advice would be appreciated

do you have this configured as a mail adress internally?
what do you mean you have configured dns in round robin (yes I know what round robin is!!!)

just if one dns server is busy they use the secondary.
I've tried the above already - I can send to all other external domains - just not this one ;(
I don't have the e-mail set up internally

Do you get a bounce from the remote MTA or does it not even get out of your network?

There was an issue where the dns servers had different cached records for the MX record for spriproducts.com - so I cleared both and now they are fine.
It doesn't even get out past our server

What if you try and 'frig it' to use an isp'd dns server, does it resolve and get out then or not?
Are you using and spam lookups, etc?.
Are you using correct revers dns lookups?

The domain resolves fine. The MX record for the domain is mail.spriproducts.com - which when I telnet to it and helo my domain is fine.
I am not doing any spam lookups.
I would assume the reverse dns is fine.

Ahh, you have created a dns entry for all the dns servers and use that for message delivery?

- nope the entries are sitting in the "cached lookups" - oddley my two dns servers did not match - so I cleared the cache out - and they now point to the same place.
I don't see how a trecert will help as the end point are probabily fire walled. And that I CAN telnet onto their mail server from the exchange server. But here you go:

OKay thats cool. If you can happily telnet onto thier dns server, from your mail server/external wan ip, then any ip blocking/filtering/spam lookup, etc, is out the question really.
If you smtp to thier mail server, and actually send an email to a live rcpt, do they get it?
