It's all driven from one text file so that when I subscribe to a new
mailing list all I have to do is add an entry to that file.  No
changing of procmail rules, no additions to muttrc.  I have attached
the filter file to this message, the comments explain it at least as
well as I can here.

# Mail filterfile, used to generate Mutt aliases and for filtering mail into 
mailboxes,
# it's used by:-
#       getAliases.py - generates mutt aliases for the mailing lists
#       getLists.py - generates list names for mutt 'subscribe' and 'lists' 
commands
#       filter.py - called by .forward, delivers mail to appropriate mail box
#
# The mutt aliases are the 'Name' in the first column, mail to the 'Name' will 
# be sent to the "To/CC matching string". Where there is more than one entry
# with the same name then mutt will send to the last one so the preferred E-Mail
# address should always be the last entry (see alug and ixion for examples).
#
# Any mail received which has a To: or Cc: which matches the "To/CC matching 
string"
# will be put in a mailbox 'Name' in directory 'Dir' under ~/Mail.  There can 
(as
# noted above) be more than one entry with the same name in the first column, 
this 
# allows E-Mail from different addresses to be delivered to the same mbox.  
Note also
# that [email protected] has to precede 
[email protected] as
# otherwise the xubuntu mails get caught by ubuntu.
#
# The fourth column (if present) is a string to be stripped from the Subject: 
line
# of messages to the corresponding list.  The string is expected to be 
surrounded
# by [].  It's also used as a 'list' match in some cases where the To: and Cc:
# fields aren't related to the list.
#
# The fifth column (if present) is an additional matching parameter to be 
matched
# as well as the To/CC destination address.  This allows Ipswich Freegle 
messages
# to be split into separate mbox destinations.  The ifc destination mbox is 
where
# a message without offer, received, taken or wanted in the Subject: will go.
#
# The [email protected] entry means that replies to subscription requests etc. will 
end up
# in a 'list' folder so that my confirmation does come from [email protected].  
(I'm not
# sure that this actually works)
