No. There is no centralized database with everybody's email. The only way you would know is by sending it, and getting it returned back to you reporting this address did not exist. <BR><BR>Sorry.. you can only check if the FORMAT of the email is valid.. nothing more.<BR><BR>Vadim C.
I mean you can easily check for formatting for an email and pop-up a message saying "not valid" etc. <BR><BR>But checking whether blabla23Mida@hotasp.com exists, is impossible. You can only get a returned email address from your Mail server saying the attempts failed after xxx tries and that this email address is unknown/invalid.<BR><BR>Vadim C.
