[Mailman-Users] Mailman digest issues

Further info on the problem is that the list admin just released 47 mails 30 minutes ago (please note that the digest_size_threshhold is now = 0, was previously 1000). Until now the list have sent 22 digest-mails with a single mail in each digest mail, all named Volume 20, but with increasing Issue number from 1 to 22. The numbering is expected, but the mails should've been send as a collection, not as individual mails.

Right now the settings are

nondigestable = True
scrub_nondigest = False
digestable = True
digest_is_default = 1
mime_is_default_digest = 0
digest_size_threshhold = 0
digest_send_periodic = 1
digest_header = ''
digest_volume_frequency = 3

There is no /var/lib/mailman/lists/LISTNAME/digest.mbox for the list in question, or any other list. Though I don't know which other lists do send digest mails.

The list admin now have Emergency-moderated the list. I guess this is just to stop all incoming traffic from being sent out, and have no effect on what the list admin do release, right?

Yes he did. I did too, afterwards.

I got the message "There was no digest to send". No messages regarding this list in /var/log/mailman/error (or any other log in this directory for that matter).

The smtp log show that the list do send message (to normal-members I guess), but I can't verify if messages are sent to digest-members. The list admin say no mails are sent to digest-members.

I am still confused, even after reading section 2.6 in http://www.gnu.org/software/mailman/mailman-admin.pdf. In my understanding, (and I know I'm wrong here) if the volume number is changed weekly, but digest mails are sent daily, all digests will contain the same volume number all week long. What is the difference between volume number and issue number, and when do Mailman send what?

How can I tell normal from digest? Will the digest mails mention Digest I the SMTP log. If so, no digests have been sent.

No errors in the error log. Cron/senddigests -l LISTNAME. However, shows

  [root at mailman.example.com]# /usr/lib/mailman/cron/senddigests -l Sci-diku-imageworld
  Traceback (most recent call last):
