In reply to message 11 from Mandakini
The sendmail_message_class will only work if you are actually using sendmail on your server.
Anyway, if you use the SENDMAIL_DELIVERY_QUEUE makes the messages be stored in the MTA queue and only try to deliver later.
If the message is not delivered due to some problem, it remains in the queue for a few days and it bounces.
You need to use the mailq command from the shell to see if the message is still in the queue and if there is any error while attempting to deliver.
