Testing validity of an Email address

Hi

Is there any way that I can check that an Email address entered by a user is actually working?

I am checking that it contains an @ and at least one . but sometimes the address is just not valid.

I would like to be able to test the Email address is functional as part of the form validation process. It would be slightly more elegant than sending them an Email with a confirmation link which they may forget to respond to or may never arrive at all.

Thanks

Yhe aspNetMX control available on DASP can be used to validate e-mail addresses. See
