# A word about this module.
#
# Postfix provides a command to control its parameters: `postconf'.
# That's the reason why I don't parse and set the values manually.
# It's much better because it can resist to changes of the Postfix
# config files.
#
# However, to `set back to default' an already changed parameter,
# there is no way to do it in the case of dynamic parameters.
# [example: I mean that for `static' parameters, which defaults to
# `0', I can set the parameter to `0' ; but for `dynamic'
# parameters such as domainname [which comes from a system call]
# I have no way]
# So for this special case, I parse the config file, and delete
# manually the correct line.
#
# gc.
