That was an example of the frequency, held mails is being approved by the moderator. When the moderator approves a bunch of mails in one week, the list admin claims that only some of the mails are posted to the list, but that some of the mails will not be sent in a digest until the next moderation a week later (example).

> if you don't want digests triggered on size
The list admin doesn't need digests sent according to size so a digest_size_threshhold = 10000 should be fine. The moderator wants to have the mails included in a digest the next noon after approving the mails.

> and your mailman is older than 2.1.16
I run Mailman 2.1.12 which is the latest available for yum update on RHEL6. I think the last Mailman version on RHEL7 is 2.1.15, but we're not there yet.

I just confirmed that senddigest is run every noon:
   /var/log/cron:Nov  8 12:00:01 p1kitlst01l CROND[18196]: (mailman) CMD (/usr/lib/mailman/cron/senddigests)
   /var/log/cron:Nov  9 12:00:01 p1kitlst01l CROND[27052]: (mailman) CMD (/usr/lib/mailman/cron/senddigests)

The error log doesn't show anything in association with the list in question. 

According to the vette log, some are discarded by moderator actions, :
   Oct 25 10:20:42 2015 (16801) Precedence: bulk message discarded by: LISTNAME-request at list.example.com
And of cause a lot of "Reason: Non-members" and spam-like messages "Reason: Your message was deemed inappropriate by the moderator.".

That's a bug <https://bugs.launchpad.net/mailman/+bug/558274> which was
fixed in MM 2.1.16, but in any case, if you don't want digests triggered
on size and your mailman is older than 2.1.16, setting
digest_size_threshhold = 10000 (KB = 10 MB) should stop digests being
triggered on size unless your list has a lot of large graphics attached
to posts. I.e. 10MB / 100 posts is still 100KB per post.


Anyway, I understood your OP to say digests were being sent only weekly
when batches of held messages are approved. If as you say,
digest_send_periodic =Yes and /usr/lib/mailman/cron/senddigests is run
by cron every day at noon, even if 50 messages are approved and 30 of
them are sent immediately in a digest (triggered on size), the other 20
should be sent in a digest the next noon.

If this is not the case, either cron/senddigests is not running every
noon or it is somehow skipping this list or encountering errors with
this list. Is there anything in Mailman's error log?
