PR Summary 😃

This PR presents several significant changes mainly aiming to improve how email attachments are handled and stored in our system, as well as correcting some formatting issues. Here's a simplified overview:

• Improved Email Attachment Storage

  • Let's start with the good stuff, we now have advanced configuration options for your email attachments in config/filament-email.php 🎉
    • You can choose where the attachments are saved using 'attachments_disk' => 'local' 🗄️
    • You can decide whether to store these attachments or not with 'store_attachments' => true 💾

• Fixed Formatting in Email Resource

  • Inside src/Filament/Resources/EmailResource.php, we've also fixed some formatting issues. There's nothing worse than a messy-looking email, right? 😅

• Enhanced Attachment Download

  • In src/Filament/Resources/EmailResource/Pages/ViewEmail.php, we've now made sure that before the system tries to download an attachment, it verifies whether the file exists and is located in the correctly configured disk 💽

• Smarter Email Logger

  • Inside our faithful src/Listeners/FilamentEmailLogger.php, we've made some significant improvements 👍
    • The system is now smarter 🧠! It checks whether to store attachments based on your configured preference 🤓
    • We've also optimized the way attachments and raw email messages are saved 📝
    • Lastly, we've improved how recipient information is formatted, making it easier to understand who the email was sent to 😊

Look forward to these fantastic updates! 🚀
