[2.x] add Brevo (Sendinblue) mail driver — core or FoF?

[imorland]

Brevo (formerly Sendinblue) Mail Driver

Brevo is a popular transactional email provider, particularly common in Europe. Symfony ships a first-party bridge (symfony/brevo-mailer) that would make implementation straightforward.

What would be involved

• New composer dependency: symfony/brevo-mailer
• src/Mail/BrevoDriver.php implementing DriverInterface
  • Settings: API key
  • buildTransport() via BrevoApiTransport or BrevoSmtpTransport
• Locale keys, unit tests, integration test update

Question: core or FoF?

Unlike Postmark (where the dep already exists), Brevo would require adding a new composer dependency to core. We're leaning towards a Friends of Flarum extension for this one — it keeps core lean and targets a more specific regional audience.

Opinions welcome — particularly from anyone currently using Brevo/Sendinblue with Flarum.

FoF - too nieche

[DavideIadeluca]

I might live in a bubble but I actually never heard of this driver before. Certainly not something that should be added in core. If at all FoF
