\n# What to do when you get several MailScanner headers in one message,
\n# from multiple MailScanner servers. Values are
\n# \"append\" : Append the new data to the existing header
\n# \"add\" : Add a new header
\n# \"replace\" : Replace the old data with the new data
\n# Default is \"append\"
\n# This can also be the filename of a ruleset.
\n#Multiple Headers = append
\n### avoid DKIM breaking.
\nMultiple Headers = add<\/p>\n

# Some people prefer that message headers are added in strict order with
\n# the newest headers at the top and the oldest headers at the bottom.
\n# This is also required if you receive a message which is authenticated by
\n# DKIM, and you are forwarding that message onto somewhere else, and want
\n# not to break the DKIM signature.
\n# **Note**: To avoid breaking DKIM signatures, you *must* also set
\n# Multiple Headers = add
\n# So if some of your users forward mail from PayPal, Ebay or Yahoo! to
\n# accounts stored on Gmail or Googlemail, then you need to set this to \"yes\"
\n# and \"Multiple Headers = add\" to avoid breaking the DKIM signature.
\n# It may be worth using a ruleset to just apply this to messages sent by
\n# the companies mentioned above.
\n# This can also be the filename of a ruleset.
\n#Place New Headers At Top Of Message = no
\n### avoid broken DKIM
\nPlace New Headers At Top Of Message = yes<\/p>\n

# Add the \"Inline HTML Signature\" or \"Inline Text Signature\" to the end
\n# of uninfected messages?
\n# If you add your own signature in your email application, and include the
\n# magic token \"_SIGNATURE_\" in your email message, the signature will be
\n# inserted just there, rather than at the end of the message.
\n# This can also be the filename of a ruleset.
\nSign Clean Messages = yes
\n### DKIM is not influenced here
\n#Sign Clean Messages = no<\/code><\/p>\n
