System I/O error (in reply to end of DATA command) for LMTP delivery

[Stephen Ingram]

Patrick-

My thought too, but nothing but success entries for all of the cyrus
commands. Is there a way to increase logging on the frontend? I seem to be
getting details on the backends, but not the frontend. That might help
diagnose this.  Ken asked for cyrus logs, but I don't really have anything
to give him because I don't see anything of consequence there.
