# Default action applied to detected spam/virus/banned/bad-header, and how to
# quarantine them
#
# Available actions:
#
#   - D_PASS: Mail will pass to recipients, regardless of bad contents.
#             If a quarantine is configured, a copy of the mail will go there.
#             Note that including a recipient in a @*_lovers_maps is
#             functionally equivalent to setting '*_destiny = D_PASS;'
#             for that recipient.
#
#   - D_BOUNCE: Mail will not be delivered to its recipients. A non-delivery
#               notification (bounce) will be created and sent to the sender.
#
#   - D_REJECT: Mail will not be delivered to its recipients. Amavisd will
#               send the typical 55x reject response to the upstream MTA and
#               that MTA may create a reject notice (bounce) and return it to
#               the sender.
#               This notice is not as informative as the one created using
#               D_BOUNCE, so usually D_BOUNCE is preferred over D_REJECT.
#               If a quarantine is configured, a copy of the mail will go
#               there, if not mail message will be lost, but the sender should
#               be notified their message was rejected.
#
#   - D_DISCARD: Mail will not be delivered to its recipients and the sender
#                normally will NOT be notified.
#                If a quarantine is configured, a copy of the mail will go
#                there, if not mail message will be lost. Note that there are
#                additional settings available that can send notifications to
#                persons that normally may not be notified when an undesirable
#                message is found, so it is possible to notify the sender even
#                when using D_DISCARD.
#
# Where to store quarantined mail message:
#
#   - 'local:spam-%i-%m', quarantine mail on local file system.
