Codeigniter SMTP Email with Amazon SES

I got that timeout message until I added the line:-

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

I have my host set as ssl://email-smtp.us-east-1.amazonaws.com

You need to do 3 things to get CI to work with Amazon Simple Email Service (SES)

1. Need to set newline = \r\n or you will get a timeout.
2. Need to set smtp_crypto to something. (New requirement)
3. Need to make sure "from" email address is approved in Amazon SES. I made my "from" email address "no-reply@mydomain.com"

Additionally, you should set up DKIM for your "from" email address to prevent emails from getting put in spam folders. This involves going into Amazon SES -> Identity Management -> Email Addresses -> DKIM, hitting the enable button, and adding 3 DNS entries to your website's DNS.

No need to do anything special to set up SPF. The envelope domain amazonses.com passes SPF.

Finally, make sure to use "reply-to" if you want users to be able to reply to an e-mail address different from your approved "from" e-mail address.

Example working code:

$obj = &get_instance();$config['protocol'] = 'smtp';$config['smtp_host'] = 'email-smtp.us-west-2.amazonaws.com';$config['smtp_user'] = 'USER';$config['smtp_pass'] = 'PASS';$config['smtp_port'] = '587';$config['newline'] = "\r\n";$config['smtp_crypto'] = 'tls';$obj->email->initialize($config);$obj->email->set_mailtype('html');// don't html_escape email header variables$obj->email->from(MV_FROM_EMAIL, $from_name);$obj->email->reply_to($from_email, $from_name);$obj->email->to($to);$obj->email->subject($subject);$obj->email->message($obj->load->view($path, html_escape($data), true));$obj->email->send();

public function enviar_email($para, $assunto, $mensagem, $formato='html'){            $this->CI->load->library('email');            $config['mailtype']     = $formato;            $config['useragent']    = 'Post Title';            $config['protocol']     = 'smtp';            $config['smtp_host']    = 'tls://email-smtp.us-east-1.amazonaws.com';            $config['smtp_user']    = 'smtpuser';            $config['smtp_pass']    = 'smtppass';            $config['smtp_port']    = '465';            $config['wordwrap']     = TRUE;            $config['newline']      = "\r\n";             $this->CI->email->initialize($config);            $this->CI->email->from('Your Verified Sender Email', 'Post Title');            $this->CI->email->to($para);            $this->CI->email->subject($assunto);            $this->CI->email->message($mensagem);            if($this->CI->email->send()):                    return TRUE;            else:                    $this->CI->email->print_debugger();            endif;    }
