email notification not sending after job completed but test message sent out without problem

Hi there,

Since I did my first posting, I had jobs which were sucessful as well as failure but the email notification didn't come through. However on Monday which was a public holidays and of course no one in the office to put the tape in and the backup failed and I received a notification of its failure. Again yesterday (Tuesday) there was a tape in and backup was succesful but did NOT receive any notification.

I found what happen is very brizzar. Anyone would throw any light on this ?
