I likely will need to see if one of our workers has a Mac at home. Can't be 
making the change on the production machine as it will impact paying 
customers.

In my original email I asked if putting that setting would help and  Barry 
Warsaw replied that it would not help. I think he tried it.

Ok, will try that with the next machine before it goes into production, but 
I guess I will need to find out if someone at work uses mail.app at home 
and can help me with the testing.. or perhaps see if someone on this list is 
willing to help with this. I could give them a test account on the next 
machine we are setting up this week.. This was not easy for us to 
troubleshoot/test/diagnose because we don't have a machine with Mail.app to 
test.
