# Note the '^[^\]]+ ' stanza: this ensures that we only match spamware
# connecting to a internal relay; if a mail came from a dynamic addr but
# was relayed through their smarthost, that's fine.

# See bug #5856, all references of "trusted" were changed to "external"

# All of the RDNS_DYNAMIC rules require that the last external relay
# did not use SMTP authentication.  These rules should not be firing on
# friendlies!
