Amazon SES STARTTLS SMTP & ExpressionEngine

I am trying to send mail using Amazon SES SMTP with STARTTLS in ExpressionEngine . I am encountering the error below.

I'm unsure why it is complaining it can't send the AUTH LOGIN command before the STARTTLS command - STARTTLS has clearly already been sent. I have tried everything I can think of, and would appreciate it if someone could point me in the right direction.

220 email-smtp.amazonaws.com ESMTP SimpleEmailService-376766033

hello: 250-email-smtp.amazonaws.com

250-8BITMIME

250-SIZE 10485760

250-STARTTLS

250-AUTH PLAIN LOGIN

250 Ok

Failed to send AUTH LOGIN command. Error: 530 Must issue a STARTTLS command first

from: 530 Authentication required

The following SMTP error was encountered: 530 Authentication required

to: 503 Error: need MAIL command

The following SMTP error was encountered: 503 Error: need MAIL command

data: 503 Error: need MAIL command

The following SMTP error was encountered: 503 Error: need MAIL command

500 Error: command not implemented

The following SMTP error was encountered: 500 Error: command not implemented

Unable to send email using PHP SMTP. Your server might not be configured to send mail using this method.

Here's a proper fix.

It is two steps (you can safely ignore the explanations if you want) and does not involve editing any non-config Expression Engine files, so you don't break your upgrade path.

It has been tested it on two Expression Engine installs (each v2.5.3 - Build Date: 20120911) and it's working perfectly.

STEP 1 of 2: Manually edit your {INSTALLDIR}/expressionengine/config/config.php file and add the following three lines at the end:

/* These email configuration variables are required for Amazon SES */
$config['email_smtp_crypto'] = 'tls'; // TLS protocol
$config['email_newline'] = "\r\n"; // SES hangs with just \n

Explanation: The first line sets the default email cryptography to TLS (which SES requires). The second line changes the email newline character from the Expression Engine default of "\n" to the RFC 822 compliant "\r\n" (which SES also requires).

STEP 2 of 2: Via your EE Admin go to "Admin -> Email Configuration" and set the following:

  • Email Protocol: SMTP
  • SMTP Server Address: tls://YOUR-SES-SMTP-SERVER:YOUR-SES-SMTP-PORT (the incredibly important part being the tls:// in front of the address)
  • SMTP Username: your SES SMTP username
  • SMTP Password: your SES SMTP password

Explanation: Once you have an SES Verified Sender Email Address and You have been granted production access to Amazon SES (both of which need to be done through Amazon's SES Management Console), you can create an AWS account with SMTP credentials via the SES Management Console. In doing this, Amazon SES will give you your own credentials.

For example it should look like this (with wacky usernames and passwords):

  • EXAMPLE SMTP Server Address: tls://email-smtp.us-east-1.amazonaws.com:465
  • EXAMPLE SMTP Username: QSKHFTQMSQAKIAIJ6GFY
  • EXAMPLE SMTP Password: PeNqC2be3IAbNyhHddTbujwekIKoQE2dAhwr3FVzObjH

To test this via your EE Admin go to "Tools -> Communicate" and send an email.

Here's my fix. I haven't had time to figure our why it works but do share if you have the time.

In your EE config file add the following settings (two tls settings as there are multiple examples of either working???):

/* SMTP mail settings
-------------------------------------------------------------------*/
$config['mail_protocol'] = "smtp";
$config['email_smtp_crypto'] = "tls";
$config['smtp_crypto'] = "tls";
$config['smtp_server'] = "AWS-SMTP-ADDRESS";
$config['smtp_username'] = "AWS-SMTP-USERNAME";
$config['smtp_password'] = "AWS-SMTP-PASSWORD";
$config['smtp_port'] = "465";
$config['smtp_timeout'] = 30;
$config['email_crlf'] = "\r\n"; 
$config['email_newline'] = "\r\n";

Then modify the Codeigniter Email.php class along the lines of this post: http://ellislab.com/forums/viewthread/158882/

The only variation I made was to set $starttls = TRUE by default.

var $starttls       = TRUE;
