# Selective SRS activation

# Activates selective SRS on a prepared mail server.
#
# The script is intentionally conservative:
#
# - ENABLED -> no changes, rc=0
# - DISABLED -> activate after explicit confirmation
# - INCONSISTENT -> abort without changes
#
# Persistent pre-SRS state is read from:
#
# /etc/postfix-srs/state.conf
#
# That state file is never overwritten by this script.
