That's an Exim complaint.  The receiver didn't respond within Exim's
time limit.  The default is 5 minutes, you can change it with the
"timeout" option on the transport (the one you've called
mailbox_lmtpunix).

So the question is why the lmtp service isn't returning soon enough.
For that, you'll need to look at your system as a whole.  _Perhaps_
upping prefork on the service entry in cyrus.conf will let things flow
better by reducing the spike loads, perhaps it'll make things worse.
