What is the purpose of using both Volumes and issues? I mean, wouldn't a single counter (like Issue) be sufficient? I ask simply to understand the nature, and relations between Digest options (where exist).

Yes, the list (lower case except for the first character, as list_lists display them) do exist, and the lists/sci-diku-imageworld/config.pck too.

No Digest mails was sent at all when digest_size_threshhold = 1000.

Thanks, that's what I meant and figured.
