Suggestion: Docker Mailserver

Problems

• requires some ignored docker-compose fields: hostname, domainname, cap_add
• Let's Encrypt certificate for emails

I think hostname and domainname aren't really needed. According to their docs, they can also be set via env vars: OVERRIDE_HOSTNAME and SRS_DOMAINNAME

But cap_add is not even supported in Docker swarm yet
😞

Im not sure what SYS_PTRACE is used for, but not setting NET_ADMIN is possible cause it is only used for fail2ban which can be disabled in the configuration file.

I still dont see much use in a one-click-app because docker-mailserver does not have an user interface so for creating accounts etc. you still would need to login via ssh?

Edit:
It looks like SYS_PTRACE (docker-mailserver/docker-mailserver#1057) is also not really needed i will setup a oneclick installer and do a test run if everything works out i will add it here.
