# Selective SRS deactivation

# was activated.

# The script is intentionally conservative:
#
# - DISABLED -> no changes, rc=0
# - ENABLED -> deactivate after explicit confirmation
# - INCONSISTENT -> abort without changes
#
# Persistent pre-SRS state is read from:
#
# /etc/postfix-srs/state.conf

# The state file and installed SRS components are intentionally retained.
