How can I control or identify bounced email?

[Hitek333]

Does anyone know a reliable way to send email (from a Perl program, using sendmail) such that any bounced mail is returned to a specified address?

Alternatively, is there a way to reliably identify bounced email once it has been returned to the sender?

I've repeatedly searched for information on how to do this, but nothing I've found has been very informative or convincing.

Maybe I'm just looking in the wrong places, but if anyone could give me some authoritative help, I'd really appreciate it :-)

sendmail -fblah@blah.com (should work)
