OK, I now know what was working (in 1.10.1) and now isn't working the way it did.
If I put the following in my muttrc:- lists mutt-users@mutt.org subscribe mutt-users@mutt.org Then my send-hooks setting a different From: for mutt-users@mutt.org work as expected in both 1.10.1 and 2.1.4. However, I'm on a lot of lists so my 'lists' and 'subscribe' commands use program generated output to populate them:- lists `~/.mutt/bin/getLists.py` subscribe `~/.mutt/bin/getLists.py` This used to work in 1.10.1 but doesn't work in 2.1.4. The output of ~/.mutt/bin/getLists.py is a single long string containing all my mailing list addresses separated by spaces. So it would seem that 2.1.4 no longer likes the space separated format, does it need a list with newline separators now? I'll try to narrow this down further by trying a very short list of mailing list names. -- Chris Green
