Override the Internet Mail Service and set smart host on Default SMTP connector
Posted on 2007-08-02
I have an Exchange 5.5 to Exchange 2003 migration environment. We have moved 99% of all mailboxes to the new server and I would now like all external smtp traffic to be delivered threw the 2k3 server instead of the 5.5 server. This as we currently having problem with bouncing mail on reply mail. It seems like mail only bounces we users do a reply.
I found out that running the consistency Adjuster on the 5.5 server might solve the issue. But as the database on the 5.5 server is not optimal and it need an offline defrag (that will take more than 10h) would I like to reroute all mail directly to the 2k3 server.
I would like to do this without uninstalling the Internet connector on the 5.5 server to be able to fall back quickly if any problems occur. I do just dont know any smart solution for this as the Internet Connector overrides any configuration that I will do on the default smtp connector on the2k3 server. This as the 5.5 and 2k3 server is in the same site.
I thought for a while that I could disable the Internet Mail connector to never run but I could not find that option. Does any one have any smart solutions. My external host is really easy to reconfigure as I there only points to an ip address for the domains that I would like to send.
