[3.x] Preparing for Symfony 6.0 & Laravel 9.0

[joostdebruijn]

Detailed description

The release of Laravel 9.0 is scheduled for January 2022 and it ships with Symfony 6.0. Swift Mailer is replaced by Symfony Mailer.

Relevant pages and PR's to have a look at:

• https://symfony.com/blog/the-end-of-swiftmailer
• [9.x] Implement Symfony Mailer laravel/framework#38481
• [9.x] Add Symfony Mailer to Upgrade Guide laravel/docs#7454

Context

This project provide some features I like which are not present in the Symfony Postmark bridge, most notably sending mails via templates. It is not likely that the Symfony Postmark Bridge will implement this functionality in their project for obvious reasons, looking at a similar case for Mandrill (symfony/symfony#37612).

Possible implementation

The changes in Symfony 6.0 and Laravel 9.0 are not backwards compatible and require a serious rewrite of this project (for example run the tests in https://github.com/joostdebruijn/laravel-postmark/tree/3.x). It may be interesting to have a look at the Symfony Postmark Bridge (https://github.com/symfony/postmark-mailer) and extend it where necessary to achieve feature parity with the module at this moment. This reduces maintance on this module while keeping the extra functionality.

Of course I'm very happy to help, but before spending time on this I would like to know what the maintainer of this package thinks of the upcoming changes and the future of this project.

Your environment

Include as many relevant details about the environment you experienced the bug in and how to reproduce it.

• Laravel Postmark Version: 3.0.0?
• Laravel Version: >= 9.0.0
• PHP Version: >= 8.0.0

Hey @joostdebruijn, I'm thinking that v3 of this project could be a complete rewrite that supports Laravel 9 + Symfony Mailer exclusively. I'll add this to the v3 milestone. I'm hoping to have time for this over the holidays / in the new year, but I'll gladly accept PRs for any of the v3 milestone items.

[craigpaul]

I got a small start on v3 tonight. Ended up deciding on a full-on rewrite, so I'll be posting some updates within this (and other relevant issues) as I go. The symfony/mailer is a bit strange, but it's starting to make more sense the further I get into this 👍

[joostdebruijn]

Nice @craigpaul! If there is something I can help with, please let me know.

Just tagged v3.0.0-RC1 which addresses the upgrade from swiftmailer/swiftmailer to symfony/mailer in Laravel 9.0. Please feel free to take it for a spin and send in any issues / PRs needed before a full release can take place 👍

[joostdebruijn]

@craigpaul I gave it a spin in a separate testproject and the implementation is looking great. Nice work!
