Final Migration Step (#6)
* first migration steps * altered issue templates * altered README * removed .travis.yml * adjusting registry & repository, Dockerfile and compose.env * Close stale issues automatically * Integrated CI with Github Actions (#3) * feat: integrated ci with github actions * fix: use secrets for docker org and update image * docs: clarify why we use -t if no tty exists * fix: correct remaining references to old repo chore: prettier automatically updated markdown as well * fix: hardcode docker org * change testing image to just testing * ci: add armv7 as a supported platform * finished migration steps * corrected linting in build-push action * corrected linting in build-push action (2) * minor preps for PR * correcting push on pull request and minor details * adjusted workflows to adhere closer to @wernerfred's diagram * minor patches * adjusting Dockerfile's installation of base packages * adjusting schedule for stale issue action * reverting license text * improving CONTRIBUTING.md PR text * Update CONTRIBUTING.md * a bigger patch at the end * moved all scripts into one directory under target/scripts/ * moved the quota-warning.sh script into target/scripts/ and removed empty directory /target/dovecot/scripts * minor fixes here and there * adjusted workflows for use a fully qualified name (i.e. docker.io/...) * improved on the Dockerfile layer count * corrected local tests - now they (actually) work (fine)! * corrected start-mailserver.sh to make use of defaults consistently * removed very old, deprecated variables (actually only one) * various smaller improvements in the end * last commit before merging #6 * rearranging variables to use alphabetic order Co-authored-by: casperklein <casperklein@users.noreply.github.com> Co-authored-by: Nick Pappas <radicand@users.noreply.github.com> Co-authored-by: William Desportes <williamdes@wdes.fr>
