Hi,

thank you so much for this project - makes selfhosting e-mail much less 
of a headache :)

Does maddy support drop-in config files, like so: maddy.conf.d/custom.conf?
v0.5 brought some new default settings which I would like to keep, but 
to run maddy some custom settings are required, which conflict with 
updated release files.

Also a very small spelling mistake in dist/fail2ban/{jail.d,filter.d}, 
where it should be maddy-dictionary-attack.conf instead of 
maddy-dictonary-attack.conf with only one "I".

All the best
Emilio
