# So, what's the difference between a trusted and untrusted Received header?
# Basically, relays we *know* are trustworthy are 'trusted', all others after
# the last one of those are 'untrusted'.
#
# We determine trust by detecting if they are inside the network ranges
# specified in 'trusted_networks'. There is also an inference algorithm
# which determines other trusted relays without user configuration.
#
# There's another type of Received header: the semi-trusted one. This is the
# header added by *our* MX, at the boundary of trust; we can trust the IP
# address (and possibly rDNS) in this header, but that's about it; HELO name is
# untrustworthy. We just use this internally for now.
#
# Finally, there's also 'internal_networks'. These are the networks that you
# control; your MXes should be included. This way, if you specify a wide range
# of trusted hosts, a mail that is relayed from a dynamic IP address via a
# 'trusted' host will not hit RCVD_IN_DYNABLOCK.
