@decentral1se @aproposnix we are generally sympathetic to try prevent corporate enclosure .... But hardly any commercial entity could run chatmail as is .... Both the open signup and the "only encrypted messages may travel freely" are geared towards public usage. If you replace both parts in chatmail you are basically using a regular postfix and dovecot and you can do this without any copying of code from the repo.
Moreover corporates prefer docker and kybernetes and what have you, not pyinfra.
