undelivered emails and PHP5 in Linux

Hello,
I am writing a program in PHP5 using mail() function. I need to know if
there's any method to check if there was return email to server
(with "undelivered" message).
I use Linux.
PLEASE HELP. Thanks.

No, because returned mail is not returned to the originating server, but to
the sender email address.

But some undeliverable mails are not immediatly returned.

If it were me, I'd go with recording outgoing mails in a database and
create a PHP script to run as a procmail filter to pick up bounces and
flag them in the DB. But its equally valid to pool a mailbox.
