Context

I need to add more aliases to the /etc/aliases file but no matter what I do I can't.
I can always use my own start-mailserver.sh script but really don't want to.

Expected Behavior

You should append to echo "root: ${POSTMASTER_ADDRESS}" >> /etc/aliases"
instead of overwritting

Actual Behavior

Possible Fix

echo "root: ${POSTMASTER_ADDRESS}" >> /etc/aliases"
