**Your software**  
My Mautic version is: 5.0.4  
My PHP version is: 8.1  
My Database type and version is: 10.6.16-MariaDB-0ubuntu0.22.04.1

**Your problem**  
My problem is:

I just upgraded from Mautic 4.x to 5.0.4 and realized that I now have to configure the email sending again due to Mautic moving to Symfony. I was previously using Amazon SES API for sending, but I am not sure how to set up the new Email DSN settings. I did not install Mautic using Composer, but rather uploaded the files to my server.

What do I need to do in order to get up and running again?

Thank you!
