Google Gmail SMTP settings not allowing me to send emails with PHPMailer

Question

I created an account on Gmail (becase the previous one was giving me the same problem) so that my application could send emails using google smtp server.

I'm using the PHPMailer library and asked it to show any log errors.

I always get a message similar to this. It vary a little, sometimes it is shorter and sometimes longer, depending on my configuration

This is my script

    $mail->Username = "[email protected]";
    $mail->Password = "mypassword";

    $mail->IsSMTP(); // enable SMTP
    $mail->SMTPDebug = 1; // debugging: 1 = errors and messages, 2 = messages only
    $mail->SMTPAuth = true; // authentication enabled
    $mail->SMTPSecure = 'ssl'; // secure transfer enabled REQUIRED for GMail
    $mail->Host = "smtp.gmail.com";
    $mail->Port = 465; // or 587
    $mail->IsHTML(true);
    $mail->SetFrom($mail->Username, 'Contato Lavile');
    $mail->addAddress($mail->Username, "Contato Lavile");
    $mail->Subject = 'Novo contato no site Lavile';
    $mail->Body = $text;
    $mail->IsHTML(true);
    $mail->AltBody = $text;

Also GMAIL is sending automatic emails to myself alerting me that a new login attempt was blocked. I even changed some settings on my gmail to make it work but everything failed

Any idead? Do you know what could be happening?

Solution

I would recommend to actually read the error message:

... 534-5.7.9 Please log in with your web browser and then try again. Learn more at 534 5.7.9 https://support.google.com/mail/answer/78754 b16sm3352387qga.48 - gsmtp

When reading this site you will find something about supporting client which provide only less secure methods of authorization. Your client is one of these so follow the link to learn how to enable support for these application in gmail.
