When smtp mail returns a "password not accepted from server"

Question

You get this error from phpmailer.

"Password not accepted from server: 535 Incorrect authentication data"

What causes this?

Answer 1

You must make sure that the Username given for the log-on is the same as the SetFrom email address.

This will return an error:

$mail->Username   = "[email protected]";      // GMAIL username 
$mail->Password   = "password";                      // GMAIL password 
$mail->SetFrom('[email protected]', 'Pagelinks');

This should not.

$mail->Username   = "[email protected]";    // GMAIL username 
$mail->Password   = "password";                      // GMAIL password 
$mail->SetFrom('[email protected]', 'Pagelinks');

When the Username and SetFrom do not match the authentication fails (according to an article found on Google).
