Exchange 2003 relaying denied when trying to relay email to another server
Posted on 2007-11-19
We have the following setup:
MX record points to a filtering company which then sends email to our site (Server a). From there we forward any email that we do not handle on our server to another one (server b) for it to process. This setup was just configured this weekend. Before Server b was the first stop and it would forward all the email to different addresses some of which resided on Serve a. Server b is a linux email server and Server a is a Exchange 2003 standard.
The reason for the relaying is that we are still in the process of moving all the users to the exchange server and we still need to email the other users. When we try to email them we get a "relaying denied" you do not have premission to send to this recipient.
This happens for anyone on server b.
The configuration we are using is that i have a second SMTP Connector setup with the address space as companya.com (which is our domain) and i also have a connector setup for the address space of *.
On our SMTP Server i have, under relay restrictions to allow all computers that successfully authenticate to relay.
Does anyone have any ideas why this woudl not be working??
