Checking that the domain exists is easy using the
CFUSION_VERIFYMAIL(MailServer, SMTPPort, Timeout) function. It'll return a
Boolean true or false id the mail server exists or not. The second part of
finding if the user actually exists on the mail server is harder. Many
(most?) mailservers do not allow this feature as its used by spammers to
gather addresses. You can use CFX_Socket to do a socket call to the mail
server in the same way your doing it with Asp (basically). If I saw the Asp
code you have I could show where what goes.
