I'm pretty sure it's a function of these two parameters to Mailman--I
suspect digest_send_periodic is set to "No", and the two messages in
December weren't big enough to cross digest_size_threshold, so they sat in
the outbound queue, waiting until enough additional content came through to
trigger the delivery, which finally happened when the last 2 messages in
the digest arrived yesterday, putting the resulting digest size across the
digest_size_threshold trigger point.

If you scrolled through the digest message, you probably noticed the last
two messages were very recent, from Feb 6th 2025, indicating this wasn't a
case of an old message stuck in an outbound queue that finally got
processed, it really was a newly-created digest message that included
messages up until Feb 6th.

*digest_size_threshold*Normally, digest members get at least one message
per day, if there have been any messages posted to the list. However, for
high volume lists, you may want to send out digests when the size has
reached a certain threshold, otherwise, the one digest they receive could
be huge. This variable controls the size threshold by specifying the
maximum digest size in kilobytes. Note that this threshold isn't exact. Set
this variable to zero to specify that there is no size threshold, in which
case no more than one digest will be sent out per day, but ensure that
digest_send_periodic is *Yes* in this case or no digests will be sent.

*digest_send_periodic*This variable actually controls whether or not a
digest is sent daily when the size threshold has not yet been met. If set
to *No*, then digests will only be sent when they are bigger than
digest_size_threshold.
