There are so many websites that provide email checker service. But how do these people develop such app? anybody here know how to
check whether the email does exist or not? How to do it programmatically?

alien3d,

i have checked that out.. Now I am working on this link. http://www.codeproject.com/Answers/544912/...plusnot#answer3
But 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.aspx
but 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

somehow 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
