Can anybody tell me to test for validity of an email address?
I mean, can one detect if an address is bogus without actually sending mail to it?
For starters, I need to see if it's in the right format ie firstname.lastname@example.org
And if the address isn't valid, I want to
Redirect to the referer with posted 'frm_Fail_Email=true'
so that I can retrieve this with $post("frm_Fail_Email')
