For incoming connections you are looking at the ratecontrol and conncontrol
features, see /usr/share/sendmail/cf/README.
For outgoing, I don't know. Why would you want to be so nice to the Yahoo.com server ;)
They should rate-limit their server if they have a problem (and I bet they do this).
There is a SINGLE_THREAD_DELIVERY option, but that's probably not what you want.
