Need to configure mailers dynamically? Laravel's Mail::build method lets you create mailers on the fly! Let's explore this flexible approach to email configuration.
Basic Usage
Here's how to create a mailer dynamically:
use Illuminate\Support\Facades\Mail;

$mailer = Mail::build([
'transport' => 'smtp',
'host' => '127.0.0.1',
'port' => 587,
'encryption' => 'tls',
'username' => 'usr',
'password' => 'pwd',
'timeout' => 5,
]);

$mailer->send($mailable);

Real-World Example
Here's how you might use it in a multi-tenant application:
class TenantMailService
{
public function sendWithTenantConfig(
Tenant $tenant,
Mailable $mailable
) {
$mailerConfig = $tenant->email_settings;

$mailer = Mail::build([
'transport' => 'smtp',
'host' => $mailerConfig->smtp_host,
'port' => $mailerConfig->smtp_port,
'encryption' => $mailerConfig->encryption,
'username' => decrypt($mailerConfig->username),
'password' => decrypt($mailerConfig->password),
'from' => [
'address' => $tenant->email,
'name' => $tenant->company_name
]
]);

try {
$mailer->send($mailable);

Log::info("Email sent for tenant: {$tenant->id}", [
'mailable' => get_class($mailable)
]);

} catch (Exception $e) {
Log::error("Failed to send email for tenant: {$tenant->id}", [
'error' => $e->getMessage()
]);

throw $e;
}
}
}

// Usage
class NewsletterController extends Controller
{
public function send(
Tenant $tenant,
TenantMailService $mailService
) {
$newsletter = new TenantNewsletter($tenant);

$mailService->sendWithTenantConfig(
$tenant,
$newsletter
);

return back()->with('success', 'Newsletter queued for sending');
}
}

Dynamic mailer configuration is perfect for multi-tenant applications, custom email providers, or any scenario where mail settings need to be configured at runtime.
