SilverStripe Email Helpers

Contains replacement Mailer object that utilizes PHPMailer to send e-mail via SMTP instead of php's mail() function. Optionally, TLS can be enabled for secure communication with the SMTP server and a charset for the e-mail encoding can be specified. In addition, embedded CSS, plus a specified external CSS file, can be inlined into the email's HTML.

Also includes a drop-in replacement for the Email class called StyledHtmlEmail. If used with HTML emails it allows you to include a style section at the top of the email which will then be inlined as style attributes on the actual html tags to promote better compatibility across email clients.

Usage

SMTP Mailer

To use the SMTP mailer add the following code to your _config.php:

$encryption = 'tls'; // use tls
$charset = 'UTF-8'; // use specified charset if set
// you can specify a port as in 'yourserver.com:587'
$mailer = new SmtpMailer('yourserver.com', 'username', 'password', $encryption, $charset);
Email::set_mailer($mailer);  // or Injector::inst()->registerService($mailer, 'Mailer');

Alternatively, any of these can be set using the config system like so:

SmtpMailer:
  host: yourserver.com
  user: username
  password: password
  encryption: tls
  charset: UTF-8

And then in _config.php:

Email::set_mailer( new SmtpMailer() );

Emogrified Smtp Mailer

If you wish to embed CSS into your email's HTML then use the EmogrifiedSmtpMailer class. Add the following code to your _config.php:

$encryption = 'ssl'; // use ssl
$charset = 'UTF-8';
$externalcssfile = 'themes/{yourtheme}/css/externalcssfile.css';  // specify the path to your css file
$SMTPDebug = 2;  // Levels 0-4 available
$logfailedemail = true;  // Log a notice with PHPMailer's error information
$mailer = new EmogrifiedSmtpMailer('yourserver.com', 'username', 'password', $encryption, $charset, $externalcssfile, $SMTPDebug, $logfailedemail);
Email::set_mailer($mailer);  // or Injector::inst()->registerService($mailer, 'Mailer');

Alternatively, any of these can be set using the config system like so:

EmogrifiedSmtpMailer:
  host: yourserver.com
  user: username
  password: password
  encryption: ssl
  charset: UTF-8
  cssfile: 'themes/{yourtheme}/css/externalcssfile.css'
  SMTPDedug: 2
  logfailedemail: true

And then in _config.php:

Email::set_mailer( new EmogrifiedSmtpMailer() );

Styled Html Email

To use the styled email, just literally use the StyledHtmlEmail class where you'd normally use the Email class and add a single style tag in the body of the email. For example:

<style type="text/css">
.bigred {
	color: red;
	font-size: 30px;
}
</style>
Hello <span class="bigred">CUSTOMERS</span>.

Would be sent as:

Hello <span style="color:red; font-size:30px">CUSTOMERS</span>.
