Hopefully an easy question:
If I'm subscribing to two different mailboxes via pop3, does the uuid part
need to be unique for each mailbox? For example, will the following cause any
problems because the uuid is the same?

- 2db99975-4977-4866-8819-d7fbbf0f9cb4@org.kernel.vger.bpf?initial_limit=10

Nope, you can reuse UUID across different mailboxes.

No problems, it's totally fine to recommend that since it saves
small amount of storage and will speed up expiry[1]
FWIW, the DB schema is in the create_state_tables() sub of
lib/PublicInbox/POP3D.pm and hopefully easily understandable
even to non-Perl hackers.
[1] of course, there's hardly any users, so I'm not sure it matters
