Hi, I work at FSF and am the main person there who works on the mailing

There are some common causes of delays.

#1, most common: When someone posts to the list from an address that has
never posted before, the message gets held until a moderator approves it
to ensure it isn't spam. Once approved, their future posts are not held
for moderation. The moderators are usually just the listhelper team,
which is about 2 people who do this a few times a day. That is described
here: That can be done much more often if
there are people who do moderation. All that needs to happen is that the
list administrator/owner gives out the moderation password to people,
and optionally add their address to the list moderator field so they get
notified when a message is held for moderation. lilypond-devel has their
list owner/admin listed as So, I would ask them about that.

#2, sometimes mailman gets hung up and delays sending out messages. We
don't really know why, but we know that in order to debug the issue, we
need to first move to mailman 3. Mailman 2 is no longer supported
upstream. There is a good chance the issue will just go away when we
move. Mailman 3 also has some nice features like allowing people to post
directly from a web archive interface (the current archive interface
will continue to exist in mailman 3, there will be 2 or more archive
interfaces). We want to have a few lists try out mailman 3 to detect any
issues before we move all the lists. Initially, the listhelpers won't be
able to help remove spam, they will need a few months to port over their
automation to mailman 3. There could be other bumps, but we will work
hard to address them and if needed, move lists back to mailman 2 while
we do. Does lilypond want one or more of their lists to be one of the
initial group to move to mailman 3?

#3, least common: sometimes there is an issue with a specific mail
server which causes delays. This can often be fixed. I'm happy to check
if that is the case, just email the details of the message to If it hasn't been posted, wait at least 3 hours from
when you sent it. Please include the message-id header, from, to,
subject, and as close to possible the exact time it was sent including
a timezone.
