NOTE: SwiftMailer has been discontinued. This module may still work, but will no longer receive updates. It is highly recommended to move to another WireMail module, such as https://processwire.com/modules/wire-mail-smtp/.
Module version 0.3.0 dropped support to Mail transport. Please change to SMTP or Sendmail transport instead. Mail transport was removed from SwiftMailer 6.x, and thus no longer works; having it selected will fall back to PHP mail().
This module extends WireMail base class, integrating the Swift Mailer mailing library into ProcessWire.
In order to use WireMailSwiftMailer, you'll just have to install the module and use ProcessWire's wireMail() function. For extensive instructions on that, take a look at /wire/core/Functions.php.
Though Swift Mailer supports Mail Transport, i.e. using PHP's mail(), that's not always sensible option. Real value of Swift Mailer is in it's Sendmail and SMTP Transports.
If you're a Gmail user and only need to send a few mails now and then, following DigitalOcean article is helpful for getting started with Gmail's SMTP server: https://www.digitalocean.com/community/articles/how-to-use-google-s-smtp-server
Basic usage is very close to how one would use PHP's native mail() function, but the order of arguments is slightly different:
$number_of_recipients = wireMail($to, $from, $subject, $body);
Like PHP's mail(), wireMail() also returns the number of recipients accepted for delivery. Note that this is not necessarily the number of recipients actually receiving your message, just the number of addresses it was sent to.
While this module should be fully functional, at least regarding the features it currently includes, it's also very rough, doesn't handle more complex things and definitely isn't intended for serious production use yet.
Another important thing to note is that as of this writing, WireMail is still a feature of ProcessWire's dev brach.
Swift Mailer is a powerful component based mailing library for PHP. If you want to learn more about Swift Mailer and the things it can achieve you should visit https://swiftmailer.symfony.com/docs/introduction.html.
