I've added _www to postfix aliases file and rebuilt the database.
I'm still getting the following

The error above is coming from the mailserver and PHP is munging the
sender, so it appears to me (and of course I am a PHP newbie) that
this is a PHP issue. If I am correct, how to configure PHP
correctly?
