Verify Email Address

I am trying to verify that the email addresses entered into our site are valid. Basically are they fake addresses or not and if I send them an email there will be an inbox associated with that address.

All I keep finding on the web is info for validating with regex... If anyone knows how to do this or knows of a site that could help, please let me know.

Thanks.

regex can only make sure that the email adddress entered is sytacticaly correct

i.e. there is an '@' in between the words and end with a .com, /.edu, or other domains (list goes bigger, as you go international)

To check if an email actually exists, a good way would be to send an email, if a failure email is recieved from the email provider, you should move that email entered into your own database, to check against before you verify another email.

Hello,

You don't HAVE to use Regex (Although it a lot more in depth). I would suggest for starting out you can to EmailAddress.Contains("@"); and EmailAddress.Contains(".");

This is a start. As for verifying, you can just make a random numbers then make concat a string together.

string toSend = "Please click the link below to register : http://MyWebSite.Com/WebMail/Register_" + EmailAddress + "_Code" + RandomNumber + ";

Granted you would have to store the ID in MySql for verification back.
