But, assuming this is a more or less standard Mailman (2.1.5), even if
no one is subscribed to the digest, when cron/senddigests runs, the
digests should still be prepared and the digest.mbox unlinked, even if
there are ultimately no recipients. The only thing that affects this
is if the list's digestable setting is No, and all this does is keep
from creating the digest.mbox in the first place.

Are there any Mailman error log entries from when senddigests ran? Did
you run it from cron or by hand. If by hand, did you run it as
'mailman' and did it produce any output? If from cron, and it produced
any output, the output was probably mailed to 'mailman' which is
probably the 'mailman' list, and where does it go from there?

Note: it is a good idea to put a MAILTO= at the beginning of Mailman's
crontab to direct any mailed output to a good place. There is normally
only mailed output if something goes wrong.

Correct, but even if there are no digest members, the digest.mbox will
be unlinked when cron/senddigests successfully runs.
