PHPMailer connection test

Question:

I've been working with PHPMailer for a while, now I'm inserting it into a more complex Content Manager and through the panel the person can insert multiple emails to be the PHPMailer Sender in various situations (for example: contact email, password recovery , registration confirmation…), then in the manager the person can modify the email access data (host, email, password and port) and save, but when saving I wanted to do a validation and only accept emails with the data that are working!

I needed a method to do a setup test!

Does anyone know this method inside PHPMailer, that it just makes a connection test, but doesn't send any email in the test act.

The code I'm trying to use is this:

    // Inclui o arquivo class.phpmailer.php localizado na pasta phpmailer
    require_once("phpmailer/class.phpmailer.php");
    require_once("phpmailer/class.smtp.php");

    $host = "mx1.weblink.com.br";
    $porta = 587;
    $email = "teste@gabrielprogramador.com.br";
    $senha = "teste123";

    $smtp = new SMTP;

    if ( !$smtp->connect($host, $porta) ) {
        // erro ao conectar
        echo 'Erro ao conectar o SMTP';
    }

    if ( !$smtp->startTLS() ) {
        // erro ao iniciar TLS
        echo 'Erro ao iniciar o TLS';
    }

    if ( !$smtp->authenticate($email, $senha) ) {
        // erro ao autenticar o usuário
        echo 'Erro ao autenticar o usuário de e-mail e senha';
    }

The host, and the access data are real, I created to do these tests!

Answer:

You can use PHPMailer's SMTP class to check the connection:

require 'PHPMailerAutoload.php';

$smtp = new SMTP;

if ( !$smtp->connect( 'host', 'porta' ) ) {
    // erro ao conectar
}

if ( !$smtp->startTLS() ) {
    // erro ao iniciar TLS
}

// Necessário enviar o comando EHLO após iniciar o TLS,
// caso contrário não será possível autenticar.
if ( !$smtp->hello(gethostname()) ) {
    // erro ao enviar o comando EHLO
}

if ( !$smtp->authenticate( 'usuario', 'senha' ) ) {
    // erro ao autenticar o usuário
}
