AllSync & AllDup

When I do a log test on the email, it works, and after the schedule backup I get an error

[TEST] AllSync Scheduler (Test) - 12/14/2007 3:48:23 PM

Below is the error.

If there is more than one recipient, they have to be separated by a comma. Does this help?

yes it does, I have been using a semi colon, like a normal email
