Thanks for the info. I'd have a couple of problems with exporting the volume because I need postfix to talk to a Unix domain socket that dovecot listens on for SASL auth. I'll go with the process manager solution - thanks for your suggestion!

Been trying to build a canned mail server for a few years so this is probably a nice solution if I can get my head around it.

Unix domain sockets work in docker shared volumes. A common use-case is to mount /dev/log into a container so that it doesn't have to run its own syslogd.

Hot tip for saving time: Always search for "docker [what you want to run]" (not just via docker, but a search engine). Even if what you find isn't a perfect match, there's a vast number of Dockerfiles on Github and elsewhere that'll give you decent starting points.
