SBS2008 + Exchange2007  External mail is being received perfectly normally. The only issue I have is with mail from  an internal smtp program called Postie.exe. It stopped working a few months ago.

The Postie program is being used by our manufacturing database application. It sends emails to internal users to notify them about various issues within the database.

When look at the Exchange smtp receive log, I see something like this:

To me, that looks ok but email from the postie program never reaches it's destination these days. I don't know what changed. Can anyone help?
