For other items (files, directories) that do not require ADD’s tar
auto-extraction capability, you should always use COPY.
docker run --rm -i lukasmartinelli/hadolint < Dockerfile
shows:
/dev/stdin:49 DL3020 Use COPY instead of ADD for files and folders
/dev/stdin:50 DL3020 Use COPY instead of ADD for files and folders
/dev/stdin:62 DL3020 Use COPY instead of ADD for files and folders
/dev/stdin:63 DL3020 Use COPY instead of ADD for files and folders
/dev/stdin:77 DL3020 Use COPY instead of ADD for files and folders
/dev/stdin:78 DL3020 Use COPY instead of ADD for files and folders

/dev/stdin:82 DL3020 Use COPY instead of ADD for files and folders

The 'ADD' instruction can handle directories as source. It is no need
to add every script in 'target/bin' explicitly. New scripts can be
added without touching the Dockerfile.
This commit adds a script nammed 'listmailuser'. './setup.sh' uses this
this script for its subcommand './setup.sh email list'. A test have
been added too.
Changed Dockerfile to include a missing configuration file for dovecot (mailboxes).
Moved Postfix setup after DKIM/DMARC/SSL setup, near the override postfix setup.
The dovecot-sieve plugin is installed and configured to apply sieve
as soon as a .dovecot.sieve file is encountered in the virtual user's
home directory (that is /var/mail/${domain}/${username}/.dovecot.sieve).
Transport has been changed in the postfix configuration to use
Dovecot LDA (see http://wiki.dovecot.org/LDA/Postfix) to actually
enable sieve filtering.
Tests have been added.
Courier and Cyrus Sasl have been removed and substituted with Dovecot which now
handle authentication for Postfix, Imap and Pop3, with support for SSL.
This allow the use of several encryption schemes for the password as well as a
single user db.
OpenDKIM keys can now be provided at the startup and will be used instead of
generating new ones (so that you don't have to change your DNS configuration).
This version builds correctly on Docker but no integration tests have been
reworked to accommodate Dovecot instead of Courier and Cyrus Sasl. As such
at present no automatic tests can be executed.
