I am successful sending emails from Perl scripts using Net::SMTP but I don't receive a failed delivery notice if the email could not be delievered. Only out of office receipts. I have used all the options that come with Net::SMTP for verification and in all cases it just tries to send. I have tried using Unix mail and I get the same thing with Message accepted for deliveryand that the Recipent is ok. Is there anything I can do?

did u check with the return status $? after using mail or mailx ?

or

possible error message in /var/adm/messages somewhere like that !!!

Hi, $? is zero whether it should have been able to send or not. I don't have /var/adm/messages. I've looked at /var/log/messages and the only thing I can see that might be related is - last message repeated 3 times but just tried sending another email to an invalid address and haven't got anything in /var/log/messages. /var/spool/mail/user mentions some message file errors but I'm not sure whether these are connected to the email.
