Bit of a strange, and probably uneccessarily complicated one.
We have an SBS server, running Exchange 2003 listening on port 97 and a Mail Gateway/Archiving product listening on port 25.
The Gateway product receives mail and passes onto exchange and exchange outbound sends out through the gateway product also... (smarthost SMTP connector).
The problem i have is that the exchange is not fully responsible for the domain in question.
In addition there is a domain (domain1.com) that is pulled into the gateway product via POP3. This account for 5 mailboxes, the rest are situated around europe.
The Exchange has been setup not to be responsible for the domain, however the limitations in the gateway product do not allow this - so i need to bypass the product for mail from these domains.
For various reasons the domain has to be the Primary mail domain for mailboxes.
The question: How can i filter mail going to domain1.com (outbound) to bypass the Mail Gateway product. I have tried creating another SMTP connector not using the smarthost feature, but does not seem to work.
Is there an article for this kind of exchange routing?
Thanks in advance.
