README

Fleet Tracking Technology — Laravel mailer microsoft_graph (Symfony Microsoft Graph bridge) + optional MailTransportResolver for database-driven settings.

Install from GitHub (Composer VCS)

In your Laravel app composer.json:

"repositories": [
    {
        "type": "vcs",
        "url": "https://github.com/YOUR_ORG/laravel-mail-transport.git"
    }
],
"require": {
    "fleet-tracking-technology/laravel-mail-transport": "dev-main"
}

Replace the URL with your real repo (HTTPS or [e-mail]:...). Then run composer update fleet-tracking-technology/laravel-mail-transport.

If your app has "minimum-stability": "stable" (Laravel default), Composer may refuse dev-main unless you allow dev for this package only:

"require": {
    "fleet-tracking-technology/laravel-mail-transport": "dev-main@dev"
}

Or tag a release on GitHub (e.g. v1.0.0) and require a normal range:

"require": {
    "fleet-tracking-technology/laravel-mail-transport": "^1.0"
}

Private repo: use a GitHub deploy token / SSH key so Composer can clone.

Troubleshooting: “Could not find a matching version” / stability

That message almost always means Composer has no source for the package:

1. Not on Packagist — this name is not published there yet. A bare composer require fleet-tracking-technology/laravel-mail-transport without a repositories entry will fail.
2. Add repositories first — use path (monorepo) or vcs (GitHub) as in the sections above, then composer update, or composer require "fleet-tracking-technology/laravel-mail-transport:dev-main@dev" after the VCS repo is in composer.json.
3. Monorepo subfolder — if the Git repo root is your whole app and composer.json for this library is only under packages/..., Composer’s vcs type cannot install that subfolder as a package. The GitHub repo for VCS install must have composer.json at the repository root (see “Publish this package to GitHub”).
4. Wrong branch — default branch might be master not main; use dev-master or rename the branch to match your constraint.

Install (path / monorepo)

"repositories": [
    {
        "type": "path",
        "url": "packages/fleet-tracking-technology/laravel-mail-transport",
        "options": { "symlink": true }
    }
],
"require": {
    "fleet-tracking-technology/laravel-mail-transport": "@dev"
}

Run composer update. Laravel auto-discovers LaravelMailTransportServiceProvider.

Publish this package to GitHub (first time)

Do not run git init inside this folder if it already lives inside another Git repo (nested .git causes confusion). Pick one:

Option A — copy to a new folder (simplest)

1. On GitHub: New repository → name e.g. laravel-mail-transport → empty, no README.
2. Copy the whole laravel-mail-transport directory to a path outside your main app (e.g. C:\src\laravel-mail-transport).
3. In that copy:

git init
git add .
git commit -m "Initial commit: Fleet Tracking Technology laravel-mail-transport"
git branch -M main
git remote add origin https://github.com/YOUR_ORG/laravel-mail-transport.git
git push -u origin main

1. In the app, switch from path to vcs (see above) and run composer update.

Option B — stay inside monorepo: git subtree split

From the root of the main repository:

git subtree split -P packages/fleet-tracking-technology/laravel-mail-transport -b fft-mail-transport-split
git push https://github.com/YOUR_ORG/laravel-mail-transport.git fft-mail-transport-split:main

Then use the GitHub URL as a vcs repository in other projects.

Env-only

Set MAIL_MAILER=microsoft_graph and MAIL_GRAPH_* in .env. Optionally:

php artisan vendor:publish --tag=mail-transport-config

Custom resolver (e.g. Spatie settings)

Implement FleetTrackingTechnology\LaravelMailTransport\Contracts\MailTransportResolver and register:

$this->app->singleton(MailTransportResolver::class, YourResolver::class);

After runtime changes: MailTransportApplier::applyFromContainer(); and Mail::purge();

Test

php artisan mail:test [e-mail]

Requirements

• PHP 8.1+
• Laravel 10 / 11 / 12 (uses Symfony Mailer 6+ already shipped with Laravel)
• Microsoft Entra app with Application permission Mail.Send + admin consent

Graph sending is implemented with symfony/http-client (no separate symfony/microsoft-graph-mailer package), so it stays compatible with Laravel 10’s Symfony 6 mail stack.
