Is there a Dockerfile for building/installing the latest Dovecot version in a Docker Image? I don't see Dovecot in the Official Repositories on the Docker Hub like almost all the other popular open source software packages that I use. Why no Official Docker repo for Dovecot? All the user contributed repos containing Dovecot in the Docker Hub seem to just install from a distribution?s repo (like Ubuntu 14.04) but these packages seem to lag the most recent version of Dovecot that I see in GitHub.
