# This setup mod script configures postfix to queue incoming messages
# into /home/user-data/mail/spool/postfix instead of the default
# /var/spool/postfix. The benefits of doing this are:
#
# 1. It will ensure nightly backups include queued, but undelivered, mail
# 2. If you maintain a separate filesystem for /home/user-data, this
# will get the queue off the root filesystem
#
