I'm in the process of preparing an SBS 2003 server for migration to SBS 2011. As a part of that project, we are also moving them to a new spam filtering platform (mxlogic). I'm running in to a really strange issue where no matter what I set the smart host address to, headers on outbound mail still show that the mail is coming from the old smart host (postini). Things I've tried:
Setting the smart host via the configure Internet SBS wizard
Setting the smart host manually in the SmallBusiness SMTP Connector
Setting the smart host on the SMTP Virtual Server
Deleting the SMTP Connector and just using the SMTP Virtual Server
Recreating the SMTP Connector via running the configure Internet wizard again
Recreating the SMTP Connector manually.
Restarting SMTP Servers before and after each of the above.
Rebooting the server before and after each of the above.
I'm frankly starting to run out of ideas.
Are there other places that the smart host settings can be stored that I am not aware of? Somewhere in the registry?
I've asked all my coworkers about this and they have never seen this before and can't think of anything else I should try. Any help would be much appreciated.
