Setup exim4 / postfix / dovecot
The minimal assumption we have is that /etc/mailpass exists
+
+I've had problems with postfix on debian:
+on stretch, a startup ordering issue caused all mail to fail.
+postfix changed defaults to only use ipv6 dns, causing all my mail to fail.
+I haven't gotten around to getting a non-debian exim
+setup.
