I'm scripting a simple registry where the user can input their name and email address. I'd like to do a quick validity check on the email address they just inputted. I can check the syntax, etc. but want check if the address exists. I realize that servers can take a long time to bounce etc. I'll just deal with this separately. Is there a better way than simply sending a test email to see if it bounces? Thanks....I've had pretty good success from the following: after checking the syntax (exactly one @, at least one . to the right of the @, etc.), if it passes the syntax check, I then set $rhs to everything to the right of the @. Then I test: if (!checkdnsrr($rhs, 'MX')) { invalid } else { valid }
