Question:
Is it possible to validate an e-mailaddress by opening a socket-connection
to the specified domein (@domain.com) and then search for username
([EMAIL PROTECTED]) to validate an e-mailaddress?
I know how to set up a socket-connection, but how do I search for the user
in the given
Yes, this is possible.
However you would need to connect to the users mailserver instead of just the domain.
Use getmxrr() to retrieve the mail exchanger associated with the domain.
To check if the user is accepted on that server you can issue a RCPT TO: command
on it and see what happens.
If the remote system has the finger service activated, that would work.
However, most servers have stopped running this and also the user generally
has a say in whether they want to be listed.
Out of curiosity, why do you want to do this?
