 # Python milters should derive from this class
-# unless they are using the low level milter module directly.  
-#
-# Most of the methods are either "actions" or "callbacks".  Callbacks
-# are invoked by the MTA at certain points in the SMTP protocol.  For
-# instance when the HELO command is seen, the MTA calls the helo
-# callback before returning a response code.  All callbacks must
-# return one of these constants: CONTINUE, TEMPFAIL, REJECT, ACCEPT,
-# DISCARD, SKIP.  The NOREPLY response is supplied automatically by
-# the @@noreply decorator if negotiation with the MTA is successful.
-# @@noreply and @@nocallback methods should return CONTINUE for two reasons:
-# the MTA may not support negotiation, and the class may be running in a test
-# harness.
-# 
-# Optional callbacks are disabled with the @@nocallback decorator, and
-# automatically reenabled when overridden.  Disabled callbacks should
-# still return CONTINUE for testing and MTAs that do not support
-# negotiation.  
-
-# Each SMTP connection to the MTA calls the factory method you provide to
-# create an instance derived from this class.  This is typically the
-# constructor for a class derived from Base.  The _setctx() method attaches
-# the instance to the low level milter.milterContext object.  When the SMTP
-# connection terminates, the close callback is called, the low level connection
-# object is destroyed, and this normally causes instances of this class to be
-# garbage collected as well.  The close() method should release any global
-# resources held by instances.
