My idea is: Replace Swiftmailer with Symfony Mailer
I think these groups of people would benefit from this idea: Users who send emails via Swiftmailer (SMTP)
Why I think they would benefit from this idea: Since Swiftmailer will be dead soon
Any code or resources to support this idea:
Are you willing to work on this idea?:
What skills and resources do you need to explore this further?
Swiftmailer will no longer be supported after November 2021. Moreover, this is one of the most important components of Mautic. Since this will happen in November, most likely its codebase will not be updated to support PHP 8.1. And this raises concerns, since Swiftmailer has a very old code base, and it is quite possible that some bugs or outdated code will occur even after the release of PHP 8.1 (also in November 2021). And it is quite possible that there are some vulnerabilities that will not be officially fixed.
Therefore, I suggest that the Mautic team start thinking about a solution to this problem in advance. I know that at the moment Mautic still does not support PHP 8.0 in the latest stable version, and all efforts are directed towards the release of version 4.0. Perhaps it will be possible to switch from Swiftmailer to another library (Symfony Mailer?) already in version 4.0?
