Looking for bokeh's script to validate an E-mail address

[HellgY]

I had it once, and i searched all over the forums and my mail box for it.
And i couldn't find it.

I will be very glad to have it if bokeh still publishes it under free licence

Thanks to all helpers!

A script isn't so much needed. Just a good Regular Expression will do it. I found this one from Felgal (a member on this site):

PHP Code:

'/^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*\.(\w{2}|(com|net|org|edu|int|mil|gov|arpa|biz|aero|name|coop|info|pro|museum))$/i'

that only checks to see if it's actually formatted properly.

bokeh has a script that can check to see that it's formatted correctly AND that the receiving server can actually verify that the account exists.

the tool itself can be found here

http://bokehman.com/validate_email

but! you have to ask bokeh for the source code, i believe.

He send me he's own version of the getmxrr() function and finally, i found it
could that be it?

It might be because the manual says the principle of it's function is returning the mail exchangers from the DNS server

If bokeh gives his permission i shall post the source in this thread

That script doesn't prove anything conclusive. If you want to verify an email address send it an email and wait for a response.

I'm not looking to prove anything, I'm looking to deprive a wrong email address, to the best my understanding, if mail exchange DNS records don't exist, then address can't be correct.

But if they don't, it just might be.

An email address can still be valid even if the is no MX record exists in the DNS. RFC 2821

How do you check mail addresses before sending any letters then?.

Oh, sorry, I thought it was only validation of format that was asked for. Ignore me.

Send a confirmation email when they sign up that they need to respond to.

I'm doing that already, i just don't want to go through the bother of sending verification mail to a mail address that doesn't exist.

I don't see it as any more bother. In fact if you are going to send an email anyway I see the realtime validation as an unnecessary step. The only time it is really of use is when you specifically did not wish to send an email.

Use AJAX.
