note 44811 added to ref.errorfunc

I wonder if is there some way to log only some commands. For example, I think I have some spammer inside my server who is sending mails with mail function. And I want to log every domain who is sending emails to some specific email addresses (i.e. *@aol.com). Could someone help me with it. Thanks. ---- Manual Page -- http://www.php.net/manual/en/ref.errorfunc.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+44811 Delete -- http://master.php.net/manage/user-notes.php?action=delete+44811&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+44811&report=yes Search -- http://master.php.net/manage/user-notes.php
