I downloaded and installed the OnOwnerChange scrip and was testing it but
no email is sent. I load a ticket and steal it no email is sent, I assign
one that is created to someone other than nobody and no email is sent. (I
do this as a test user so that I will get emails).

Where else should I look
I added the scrip (I am using rt 2.0.15)

<>< Proverbs 3:5-6 “Trust in the Lord with all your heart and lean not on
your own understanding;
in all your ways acknowledge him, and he
will make your paths straight.”
