Challenges with randomly set/reset passwords

[fraseracct]

I observed issues during container restarts using randomly set/reset passwords. I had to set several passwords to stabilize my environment. Here are the values I set.

MYSQL_ROOT_PASSWORD= >> iredmail-docker.conf
VMAIL_DB_ADMIN_PASSWORD= >> iredmail-docker.conf
VMAIL_DB_PASSWORD= >> iredmail-docker.conf
AMAVISD_DB_PASSWORD= >> iredmail-docker.conf
SA_BAYES_DB_PASSWORD= >> iredmail-docker.conf

Consider updating the README.md section "All SQL passwords are randomly set/reset by default each time you launch or relaunch the container. If you don't like this, please set fixed passwords in iredmail-docker.conf, e.g. MYSQL_ROOT_PASSWORD=." to include these additional values.
