This is a simple implementation of a mail_queue. We need to have a Database table for the same which will have rows corresponding to the emails to be sent. This implementation uses SWIFTMailer to send SMTP emails.

1. Install the dependencies from composer
2. Update the proper configuration for the SMTP, DATABASE and Async Location in /config.php
3. Make sure /applogs/ is a writable folder with proper permissions
4. Import the SQL schema + data from /sql/mail_queue.sql
5. Create a vhost and mark it as the host for the async credentials
