It's a bug in sendmail 8.7.1 associated with the sendmail
option MinQueueAge.  The fix is in 8.7.2.
 
 
From the sendmail 8.7.2 RELEASE_NOTES
 
 If MinQueueAge was set and a message was considered but not run
                during a queue run and the Timeout.queuereturn interval was
                reached, a "timed out" error message would be returned that
                didn't include the failed address (and claimed to be a warning
                even though it was fatal).  The fix is to not return such
                messages until they are actually tried, i.e., in the next
                MinQueueAge interval.  Problem noted by Rein Tollevik of
                SINTEF RUNIT, Oslo.
