Validates an email address by checking for MX records and performing and SMTP triplet connection

SMTP_Validate_Email

Perform email address validation/verification via SMTP., _(*1)

The class retrieves MX records for the email domain and then connects to the domain's SMTP server to try figuring out if the address really exists., _(*2)

Some features (see the source for more)

• Not really sending a message, gracefully resetting the session when done
• Command-specific communication timeouts implemented per relevant RFCs
• Catch-all account detection
• Batch mode processing supported
• MX query support on Windows without requiring any PEAR packages
• Logging and debugging support

Basic example

<?php

use SMTPValidateEmail\SMTPValidateEmail;

$from = 'sendingemail@test.test';
$email = 'emailtoverify@test.test';

$validator = new SMTPValidateEmail($email, $from);
$smtp_results = $validator->validate();

print_r($smtp_results);

Array usage

The class supports passing an array of addresses in the constructor or to the validate() method. Checking multiple addresses on the same server uses a single connection., _(*3)

<?php

use SMTPValidateEmail\SMTPValidateEmail;

$from = 'a-happy-camper@campspot.net'; // for SMTP FROM:<> command
$emails = array(
    'someone@somewhere.net',
    'some-other@somewhere-else.net',
    'someone@example.com',
    'someone-else@example.com'
);

$validator = new SMTPValidateEmail($emails, $from);
$smtp_results = $validator->validate();

// or passing to the validate() method
// $validator = new SMTPValidateEmail();
// $smtp_results = $validator->validate($emails, $from);

print_r($smtp_results);
