Disclaimer: "I don't know PHP, but ..."

The standard answer when people ask how to do this in Perl is "don't".
RFC 822 is evil to parse, and the work involved in doing that doesn't
actually give you a great deal of benefit. After all, most addresses
that look valid won't be deliverable anyway. The only way to tell if an
address is deliverable is really to try sending something to it.

Have I misunderstood why you need this?
