sendmail only queues if 1) the initial attempt suffered a temporary 
failure or 2) queueing mode was set.

Otherwise sendmail will immediately attempt to deliver the mail. Check 
the headers of the test mail in question to find out where there was a 
latency. If you have a large queue already then that is your problem and 
setting QUEUE=10s will not help.
