# Just check the most recent handover; the connection to a internal host.
# This way a legit sender can send to their MSA using that HELO (quite a few
# MUAs will do that), but a spammer gets caught. (List of domains comes from
# the drop-down list on the Mail.com signup page.)

#describe FAKE_HELO_MAIL_COM_DOM Relay HELO'd with suspicious hostname (mail.com)
# ---------------------------------------------------------------------------
# Interesting new feature; spamware HELO'ing, from a dialup IP addr,
# using that IP's rDNS entry. We can catch this easily. There aren't
# many legit mailservers calling themselves
# 'dhcp024-210-034-053.columbus.rr.com'. ;)
#
# 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 internal
