If I understand you, put one or both of these in main.cf:

defer_transports=smtp
#disables smtp transport until you issue sendmail -q

disable_dns_lookups = yes
#I'm not sure, but apparently postfix doesn't check with DNS during
#SMTP dialogs.

I see something that may be similar. Mailman is batching messages as I
want -- 5 or 10 at a time. Postfix sends to the upstream MTA one at a
time. Is this what you're seeing?
