In general terms:

You have to create a local mailer which delivers immediately. Add a
local_net_config rule that uses the rule.  If I remember correctly this is
described in one of the files in /usr/doc/sendmail

Set the regular mailer as expensive. Plus alter the queue processing in
/etc/init.d/sendmail.

Hope you can take it from here. It has been a while since I set this up.
