I tried chancing it to plain and get the same error with the same message.

When I tried this there was not an *imap log* buffer. When I set
nsm-trust-local-network to t there's an *imap log* buffer, though that's
not as useful I suppose. But at least the logging is working?

Correct, other than the message I originally reported (Warning: Opening
nnimap server on LocalMail...failed: ; Unable to open server
nnimap+LocalMail due to: Buffer *nnimap localhost nil *nntpd** has no
process)

Thanks,
