This module is for SilverStripe v3 only. SilverStripe 4 supports many email services through configuration only by providing a wrapper for SwiftMailer. Postmark takes some extra work to set up though, because SS4 uses SwiftMailer v5, and the official Postmark adapter for that version is incomplete. Here are a couple of different approaches for working around the issue:
This module lets you send SilverStripe emails through the official Postmark PHP library, falling back to PHP's built-in sendmail() if Postmark is unreachable.
- PHP 5.5+
- SilverStripe ^3.1
- Postmark-PHP
Note: an alternative Postmark Mailer class that works with older versions of SilverStripe and PHP is available here.
Install with Composer. Learn how
composer require "jonom/silverstripe-postmark-mailer:^1.0"
You will need to provide a PostmarkAPP API key and at least one verified email address (Sender Signature) that you have set up in your Postmark account. If you try to send an email from a non-verified address, the From address will be changed to the first verified address you provided and a Reply-To field will be set with the original From address.
In your project's _config.php file:
Email::set_mailer(new PostmarkMailer());or:
// Send email through Postmark in live environment only
if (Director::isLive()) {
Email::set_mailer(new PostmarkMailer());
}In your project's _config/config.yml file:
PostmarkMailer:
api_key: 'your-key-goes-here'
sender_signatures:
- '[email protected]'
- '[email protected]'If you want to boost morale of the maintainer you're welcome to make a small monthly donation through GitHub, or a one time donation through PayPal. ❤️ Thank you!
