I think I have done before but see attached files anyway.
The mutt configuration works using two very simple Python scripts as
follows (I've attached these two scripts as well) :-
#
#
# Mailing lists, see ~/.mutt/filter and ~/mutt/bin/filter.py for details.
#
lists `~/.mutt/bin/getLists.py`
subscribe `~/.mutt/bin/getLists.py`
#
#
# getAliases.py gets aliases for mailing lists from the filter file
#
source ~/.mutt/bin/getAliases.py|
Here's a section of the file 'filter' which is what I change to add or
remove mailing lists (and some other things):-
letsencrypt Li list-id help.community.letsencrypt.org
mercurial Li list-post [email protected]
mercurial Li list-post [email protected]
mopidy Li list-id q&a.discourse.mopidy.com
mutt Li list-post [email protected]
netman Li list-post [email protected]
owfs Li list-post [email protected]
Owfs-developers
openLibrary Li list-post [email protected]
photini Li list-post [email protected]
postfix Li list-post [email protected]
pfx
quodlibet Li list-post [email protected]

My Python script does what procmail does, no need for procmail as well.
