That could be the reason.

Did he press "Submit Your Changes" after setting _send_digest_now to
Yes? If so, and if there were digested messages and digest members with
delivery enabled, something else is wrong.

What response did he get when pressing "Submit Your Changes" after
setting _send_digest_now to Yes? What's in Mailman's error log.

digest_volume_frequency has nothing to do with how often periodic
digests are sent. It only controls how often the vvv is incremented and
ii is reset in the "List_name Digest, Vol vvv, Issue ii" Subject: header
of the digest.

Your MTA logs and Mailman's smtp log. Also, digest messages are
accumulated in lists/list_name/digest.mbox, and when a digest is sent,
this file is removed.

Mailman's error log and in the output from cron/senddigests (for
periodic digests.

Note, that often the output, if any, from Mailman's cron jobs is mailed
to the 'mailman' user which happens to be the site list. If the site
list is not configured to accept non-member posts, and the site admin is
not a member of the site list, this output is often lost.

You can either set the site list as above or add a MAILTO= directive
with a deliverable address to Mailman's crontab.

They have nothing to do with each other.

Note you can run cron/senddigests manually for all or a single list. See
'cron/senddigests -h'.
