How to generate *.eml file with Swift Mailer (in Laravel)-CodePudding

I want to create an *.eml file, which I want to use as a template for Outlook. My project is using Laravel.

I’m aware of the SwiftMailer function toString(), which is used to convert the message into MIME-format. See below for my approach. That code generates the header properly, but body and and html-template(blade), which I pass to the method, won’t be displayed the way I want to...

The Mail mustn't be send, but generated.

I didn’t find any related problems on the Internet. Saving generated *.eml files doesn’t seem to be popular :) Does anyone can think of a solution?

public function generateEmlFile(Request $request) {
    //...

    $data = array('name' => "recipient");

    Mail::send('emails.ordering', $data, function($message) {
        $message->from('[email protected]');
        $message->to('[email protected]');
        $message->subject('Subject');

        $content = $message->toString();
        dd($content);
    });

    return true;
}

a dump of the work so far:

Message-ID: <4900a58cfb9b22900d8500b6e80f3022@examlpe-domain>\r\n
Date: Wed, 17 Jul 2019 15:51:38  0200\r\n
Subject: Subject\r\n
From: [email protected]\r\n
Reply-To: example-project <[email protected]>\r\n
To: [email protected]\r\n
MIME-Version: 1.0\r\n
Content-Type: text/plain; charset=utf-8\r\n
Content-Transfer-Encoding: quoted-printable\r\n

I recommend not to use any external Swiftmailer transport extension or do any custom coding in EventServiceProvider. The following solution is much simpler:

Create logdir logs/emails

Add an extra channel configuration to config/logging.php:

    'channels' => [

        // ...

        'emails' => [
            'driver' => 'single',
            'path' => storage_path('logs/emails/' . \Illuminate\Support\Str::uuid() . '.eml'),
            'level' => 'debug',
        ],

And then simply use the following in your .env:

MAIL_MAILER=log
MAIL_LOG_CHANNEL=emails

That way, you get wonderful logs/emails/<UUID>.eml files with only one drawback (that does no harm): The first line (before Message-ID: ...) of the email header is prefixed with log formatting prefix [_TIMESTAMP_] local.DEBUG: . As a non-standard email header is ignored by all/most email clients, this should be no issue in development.

you can listen to the LogSentMessage event

diff --git a/app/Providers/EventServiceProvider.php b/app/Providers/EventServiceProvider.php
index 723a290..f7568ec 100644
--- a/app/Providers/EventServiceProvider.php

        'Illuminate\Mail\Events\MessageSent' => [
            'App\Listeners\LogSentMessage',
        ],
     ];

after adding these 3 lines run php artisan event:generate

this should create the file app/Listeners/LogSentMessage.php

inside the handle function you can access the complete msg -> $event->message->toString();

If you are not sending the email in the application, there's no need to use the laravel Mail facade.

There is a extension for Swiftmailer that supports saving emails as .eml files https://github.com/geekdevs/swift-mailer-extensions
