# Handle email responses sent to us.

# This script is invoked as a pipe command, i.e. with the raw email message on stdin.
# - If a message is identified as a permanent bounce, the user is marked as having a
#   bounced address, and will not be sent any more messages.
# - If a message is identified as an out-of-office autoreply, it is discarded.
# - Any other messages are forwarded to config.get("FORWARD_NONBOUNCE_RESPONSES_TO")
