Question about Chasquid

[Jason Howard]

Hi, I am new to setting up my own server, usually I use some type of control panel in the past, but I want to have as lean of server as possible.   How are attachments handled with this Smtp server?  I was looking for a way to pipe the emails into a mysql database with a reference to the attachments / alias so that I could use them in my custom application for a project I am doing for my family.  

If we already have a SSL certificate from lets encrypt after setting up caddyserver is it possible to use the same certificate for the same domain as the email?

Is there a video tutorial on setting this system up and covering the configuration?  

Thanks,
Jason
