Situation: 10 mailboxes on a Courier IMAP server.
Multiple users on multiple locations, all sharing all mailboxes.

Synchronize accounts produces loads of 0x800CCC0F errors.
Once I try to sync all accounts at once, loads of errors are
reported, on random mailboxes and even when I just finished an
individual sync.

Tools, Accounts, Mail tab, Properties, Advanced tab, ...
Are you sending and receiving on port 143?

Yes.

Or, to be more precise: IMAP communicates on port 143.

(SMTP still uses port 25. But there is never any mail in the
outbox. So that cannot cause any of the errors.)
