ARCHIVE_SCRUBBER = 'Mailman.Handlers.Scrubber'

# This variable defines what happens to text/html subparts.  They can be
# stripped completely, escaped, or filtered through an external program.  The
# legal values are:
# 0 - Strip out text/html parts completely, leaving a notice of the removal in
#     the message.  If the outer part is text/html, the entire message is
#     discarded.
# 1 - Remove any embedded text/html parts, leaving them as HTML-escaped
#     attachments which can be separately viewed.  Outer text/html parts are
#     simply HTML-escaped.
# 2 - Leave it inline, but HTML-escape it
# 3 - Remove text/html as attachments but don't HTML-escape them. Note: this
#     is very dangerous because it essentially means anybody can send an HTML
#     email to your site containing evil JavaScript or web bugs, or other
#     nasty things, and folks viewing your archives will be susceptible.  You
#     should only consider this option if you do heavy moderation of your list
#     postings.
#
# Note: given the current archiving code, it is not possible to leave
# text/html parts inline and un-escaped.  I wouldn't think it'd be a good idea
# to do anyway.
#
# The value can also be a string, in which case it is the name of a command to
# filter the HTML page through.  The resulting output is left in an attachment
# or as the entirety of the message when the outer part is text/html.  The
# format of the string must include a "%(filename)s" which will contain the
# name of the temporary file that the program should operate on.  It should
# write the processed message to stdout.

# typically receive messages with outrageous dates.  Set this to 0 to retain
# the date of the original message, or to 1 to always clobber the date.  Set

# Most character set encodings require special HTML entity characters to be
# quoted, otherwise they won't look right in the Pipermail archives.  However
# some character sets must not quote these characters so that they can be

# These variables control the format and frequency of VERP-like delivery for
# better bounce detection.  VERP is Variable Envelope Return Path, defined
# here:
#
# http://cr.yp.to/proto/verp.txt
#
# This involves encoding the address of the recipient as we (Mailman) know it
# into the envelope sender address (i.e. the SMTP `MAIL FROM:' address).
# Thus, no matter what kind of forwarding the recipient has in place, should
# it eventually bounce, we will receive an unambiguous notice of the bouncing
# address.
#
# However, we're technically only "VERP-like" because we're doing the envelope
# sender encoding in Mailman, not in the MTA.  We do require cooperation from
# the MTA, so you must be sure your MTA can be configured for extended address
# semantics.
#
# The first variable describes how to encode VERP envelopes.  It must contain
# these three string interpolations:
#
# %(bounces)s -- the list-bounces mailbox will be set here
# %(mailbox)s -- the recipient's mailbox will be set here
# %(host)s    -- the recipient's host name will be set here
#
# This example uses the default below.
#
# FQDN list address is: mylist@dom.ain
# Recipient is:         aperson@a.nother.dom
#
# The envelope sender will be mylist-bounces+aperson=a.nother.dom@dom.ain
#
# Note that your MTA /must/ be configured to deliver such an addressed message
# to mylist-bounces!
VERP_FORMAT = '%(bounces)s+%(mailbox)s=%(host)s'

# The second describes a regular expression to unambiguously decode such an
# address, which will be placed in the To: header of the bounce message by the
# bouncing MTA.  Getting this right is critical -- and tricky.  Learn your
# Python regular expressions.  It must define exactly two named groups,
# mailbox and host, with the same definition as above.  It will be compiled
# case-insensitively.
VERP_REGEXP = r'^[^+]+?\+(?P<mailbox>[^=]+)=(?P<host>[^@]+)@.*$'

# A perfect opportunity for doing VERP is the password reminders, which are
# already addressed individually to each recipient.  This flag, if true,
# enables VERPs on all password reminders.
VERP_PASSWORD_REMINDERS = 0

# Another good opportunity is when regular delivery is personalized.  Here
# again, we're already incurring the performance hit for addressing each
# individual recipient.  Set this to true to enable VERPs on all personalized
# regular deliveries (personalized digests aren't supported yet).
VERP_PERSONALIZED_DELIVERIES = 0

# And finally, we can VERP normal, non-personalized deliveries.  However,
# because it can be a significant performance hit, we allow you to decide how
# often to VERP regular deliveries.  This is the interval, in number of
# messages, to do a VERP recipient address.  The same variable controls both
# regular and digest deliveries.  Set to 0 to disable occasional VERPs, set to
# 1 to VERP every delivery, or to some number > 1 for only occasional VERPs.

# The envelope sender is set by the SMTP delivery and is thus less easily

# If there is existing bounce info for this member, we look at the last bounce
# receive date.  If this date is farther away from today than the `bounce
# expiration interval', we throw away all the old data and initialize the

#
# Otherwise, we increment the bounce score.  If we can determine whether the
# bounce was soft or hard (i.e. transient or fatal), then we use a score value
# of 0.5 for soft bounces and 1.0 for hard bounces.  Note that we only score
# one bounce per day.  If the bounce score is then greater than the `bounce
# threshold' we disable the member's address.
