I'm having trouble getting digests to work.
What do you mean by that? What do you expect to happen? What does happen? Are there any messages in the logs?
If the messages were actually sent and "something" happened downstream, there would be messages indicating connection and a message describing deliveries in Mailman's smtp.log, as well as the usual set of entries for each recipient in your MTA's log.
If digests are simply disappearing, is it possible that there are no digest recipients on that list? Or is it possible that digests aren't enabled for that list? Are you sure digests were being collected (if digests aren't enabled, it would not be)?
When I try to manually send one, it does nothing, and then the digest gets deleted (I guess?).
Why do you think it did nothing? Or is that just a guess?
By design Mailman holds to the main principle of email: You must not lose mail. The principal means to this end is a formal chain of custody: each participant in the mail system must confirm that the next hop has accepted responsibility for a message before purging its storage. Mailman does not delete messages (I assume including the digest) before confirming that the next hop has accepted responsibility. If that assumption is incorrect, it's a devastating bug.
If there was a digest, most likely Mailman did send it but it's stuck somewhere downstream in the system. The exception would be as mentioned above, if there were no recipients.
Mark answered your other questions. Feel free to ask if there are any unclear points.
