alien3d, i have checked that out.. Now I am working on this link. http://www.codeproject.com/Answers/544912/...plusnot#answer3But still, I cannot work around with it. I used EmailVerify.dll from this website --> http://www.codicode.com/art/free_asp_net_e...r_verifier.aspxbut the search is limited to gmail accounts only.

U can't, that's to protect the email owner from spam and server can choose not to reply or bounce if email address doesn't exists.

verification of emails can be tedious & time consuming that's y service provider charging expensive for it but it's good to keep a healthy database from time to time simple google search will get you results like telnet method mentioned above http://lifehacker.com/5697360/how-to-verif...is-real-or-fakesomehow if u using newsletter services it'll update ur mailing list with good or bad addresses

you can create one seems to work but it will never be 100% working for all..
some mail server bounce, some mail server ignore etc, you can't change their setting too
