Q A
Branch? 7.3
Bug fix? no
New feature? yes
Deprecations? no
Issues Fix #48297
License MIT

Adds 'require_tls' param which can be set to true to enforce the use of TLS/STARTTLS within the ESMTP transport.
This was discussed in #48297.
These changes are based upon patches I've been maintaining for my own projects.

This is my first PR to Symfony, I've tried to follow the guide as best as possible, and I was also using #53621 as a general guide. There are some other ways I could have gone about things, but I've tried to avoid touching as much existing Symfony code as possible.

In #48297, nicolas-grekas mentioned unifying such an option with auto_tls under a tls option, but I think these are distinct options which may not be as clear combined (in addition to any expectations of such an option disabling/enabling TLS in general).

Hey!

I see that this is your first PR. That is great! Welcome!

Symfony has a contribution guide which I suggest you to read.

In short:

  • Always add tests
  • Keep backward compatibility (see https://symfony.com/bc).
  • Bug fixes must be submitted against the lowest maintained branch where they apply (see https://symfony.com/releases)
  • Features and deprecations must be submitted against the 7.3 branch.

Review the GitHub status checks of your pull request and try to solve the reported issues. If some tests are failing, try to see if they are failing because of this change.

When two Symfony core team members approve this change, it will be merged and you will become an official Symfony contributor!
If this PR is merged in a lower version branch, it will be merged up to all maintained branches within a few days.

I am going to sit back now and wait for the reviews.

Cheers!

Thanks for the review @mtarld.
I've now addressed both of the raised points, and have re-based the branch to the current 7.3 state.

LGTM.

We need to make it clear in the doc that this option makes sense with the "smtp" scheme (since TLS is always enabled with "smtps" anyway).

Adds 'require_tls' param which can be set to true to enforce
the use of TLS/STARTTLS within the ESMTP transport.
