If you have a long queue, my impression is that a 10-minute time is too
short. We use an hour. Somewhere in the sendmail docs (or in the
sendmail Nutshell Handbook) is a warning about too-short settings of -q.
Your mileage may vary, but yes, don't set your queue run time too short.
Please keep us (or me, at least!) in touch about what you find.
