Is it only logging that stops, or does everything else stop as well? How
about sending SIGHUP again, does it fix the problem? Or if not, does
SIGUSR1 fix it (SIGUSR1 only reopens log files)?

The INDEX=%h/Mail/ shouldn't be needed because the default directory is
the same as the directory you gave after mbox:, ie. same one.

Shouldn't you also add :INBOX=%h/.inbox here?

And here?

If it's finding everything correctly, then only problem you have is that
you have set mail_debug=yes. The throttling message comes because imap
process is sending log messages too quickly and Dovecot thinks it could
benefit from having to be stalled for a while in case it's trying to
flood your logs full.

%h works in all cases, ~/ works only after "mbox:" or "maildir:" string,
so %h is preferred until the location/default_mail_env setting itself is
split to multiple settings (in Dovecot 2.0).
