email ID exists or not in PHP

Job ID: 33712148

Budget: $30 – $250 USD

However, just because the email is not rejected, does not mean the user exists.

There are two ways to check :

1) You can connect to the server, and issue a VRFY command. Very few servers support this command, but it is intended for exactly this. If the server responds with a 2.0.0 DSN, the user exists. VRFY user

2) You can issue a RCPT, and see if the mail is rejected. MAIL FROM:<> RCPT TO:<user@domain>
If the user doesn't exist, you'll get a 5.1.1 DSN.

NOTE* Don't send proposals if you're busy and cannot start immediately.
