Hi,

first you make a great job... mailpit is awesome!

2 small things, can we make regex case insensitve?

currently it would only work like this:

MP_SMTP_RELAY_ALLOWED_RECIPIENTS: "@example\.de$|@EXAMPLE\.DE$"

and btw i musst set escape this "" with "\"... otherwise docker will not except it :)

Thx!

Thanks, I'm glad you like it @q16marvin!

Actually you can set this yourself MP_SMTP_RELAY_ALLOWED_RECIPIENTS: '(?i)@example\.de$' (I think a single quote works in a docker-compose file). Regular expressions are a little different in Go - see https://regex101.com/r/JUehoJ/1
