Multiple Domain Issues using Recipient Policies
Posted on 2007-10-03
We have an Exchange 2003 server that is hosting 3 domains through Recipient Policies. We have not really had any problems until recently where an external mail server is blocking mail from one of our domains, because it does not match the domain of our mail server.
The other issue is, we are unable to send mail from other domains.
Our setup is as follows:
mail.abc.com is our mail server
the three domains we host are mail.abc.com, mail.123.com and mail.xyz.com
We have recently been unable to send mail to one of our vendors because the mail host name mail.abc.com does not match my e-mail address of firstname.lastname@example.org
I tried to test the problem by sending an e-mail from email@example.com to the vendor, but I got the error message You do not have permission to send to this recipient.
I would like to be able to send mail from our other domains, but I also would like to have our other domains able to match the mail server, so we are not viewed as SPAM.
Let me know if this makes sense. Please help.
