Re: socket - e-mailaddress validation

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. Also you can use a local SMTP server that supports the VRFY (verify) command to check if the address is accepted. Google for 'RFC SMTP' for more details on the SMTP protocol. bvr.
