Funny you should bring this up now, I tried it just a couple of days ago, adding a local ruleset to my sendmail.mc file that would tempfail any emails that resulted in a temporary or permanent DNS failure. My idea was to watch it for a day or two and if it worked out, change it to reject mail when there was a permanent DNS error. That way, any mail that was attempted during my test would hopefully get re-sent if I decided to take it out. As it turned out, I did take it out. I looked at the sendmail log the next day and found that there is a lot of screwed up DNS out there. We were tempfailing legitimate higher-ed related newsletters, as well as email from a large credit union in our town (in fact, it is the largest credit union in Alabama). I would still like to do this one day, but I figured that this was not my ditch to die in on this particular day :-) HTH...
