I haven't seen anyone else replying, but there doesn't seem anything
anomalous with the output.  The session commands-repliesd is
is more or less what I expect, although to make sense of this, you'll
have to splice the input and output files together using timestamps to
see the sequential flow of data.

I forget what the symptoms you originally reported, but theoretically,
you could simulate either client or server by feeding in the above data
and see how the other end behaves.

If dovecot is serving out the correct data, then TB is somehow
misinterpreting it.

Typically, if some resource limit is hit, one side or the other will
create a log or notification.  Your INBOX is large, but not outrageous.
You can test it directly by creating smaller subsets of the INBOX messages
and see if the problem goes away.
