Email verifier

[dips255]

Please suggest a reliable component for email verification that can be implemented with asp coding

Microsoft's CDOSYS.

Since it's included with all Windows systems, it qualifies as the most reliable. Any other component you would have to install yourself.

Or were you only talking about verifying the format of a user-input email address??

In that case, use the REGEXP object that is builtin to VBScript.

Thanks

Can you please help me with syntax of email validation with CDOSYS.
My intention is to prevent mails getting bounced. Ive implemented the REGEXP for format validation.

Oh, is *THAT* what you meant!!

I have no idea how to do that kind of validation *except* by attempting to send an email and then waiting for the bounce message. But be aware that *some* email systems do not "bounce". They just silently accept the messages and then throw them away if the recipient doesn't exist. And of course no system will tell you if the user has a spam filter that is simply throwing away your email as it is received.
