Unable to send email using PHP SMTP.

Answer 1

A common cause of this is the way that CodeIgniter interacts with the SMTP server with regards to line breaks. Your SMTP server might require \r\n and CodeIgniter is using \n.

There is an easy fix: after your $this->email->initialize(), add the following:

$this->email->set_newline("\r\n");  

That should get it working for you.
