asked on
email domain name showing as the wrong address
Hi all,
I have a fairly annoying problem.
Setup:
Exchange 2003 server - Country A
Domain 1 - example.net
Domain 2 - example.net.au
Domain 3 - different.com
Users - Country A - Domain 1,2 - No problems
Users - Country B - Domain 3 - Problems
The problem is as follow:
2 of 3 users in Country B, using RPC/HTTP Outlook Anywhere are receiving bounced email from clients / external people. They are sending out as user@different.com but when an external person is sending to them they are getting bounceback email from user@example.net.
Users in Country B are have multiple SMTP address on their AD account, with different.com as the primary. 'Update based on recipient policies' is unticked.
If you need any further information, or this is written so terribly that you can't understand it, please let me know.
I have access to the Exchange server, DNS domain setup etc.

the mx.1 address is our Spam/Filtering provider
So you think that is the place where it is being rejected?

I don't think it is written :)
TO:<internal.user@www.example.net>:
host mx1.xxx.com.au [xxx.xxx.xxx.xx]: 550 #5.1.0 Address rejected.
TO:<internal.user@www.example.net>:
host mx1.xxx.com.au [xxx.xxx.xxx.xx]: 550 #5.1.0 Address rejected.
ASKER
Sorry I don't know what you mean there?
I mean that this line >> host mx1.xxx.com.au [xxx.xxx.xxx.xx]: 550 #5.1.0 Address rejected. <<<<
means that mx1.xxx.com.au [xxx.xxx.xxx.xx] replied Address Rejected so the problem can only be from the anti spam
means that mx1.xxx.com.au [xxx.xxx.xxx.xx] replied Address Rejected so the problem can only be from the anti spam

Ah ok. Thanks for that, I have previously spoken with them and they seemed to think it was all fine at their end. I will give them another call and get to the bottom of it!

That's what I thought initially, but I've confirmed the user is entering the address correctly and not with a WWW prefix
Should hear back from the Spam provider today and will report back
Thanks all

host mx1.xxx.com.au [xxx.xxx.xxx.xx]: 550 #5.1.0 Address rejected
my best guess is that mx1.xxx.com.au is some external spam filter and it is not configured correctly for user@different.com, in all cases this is the guy rejecting the messages.
is this mx1.xxx.com.au your exchange server?
