Wouldn't it be true that the passenger would have to go through security screening for an international to domestic connection in any country which requires going through customs at the first point of entry (since the passenger had to get his/her checked baggage for possible customs inspection)?.
I've seen plenty of exceptions to this. The one I recall the most is Mexico like the other poster noted.
I do enjoy countries with either sterile international transfers or non-burdensome I&C (KEF, for example, where I've re-entered Iceland just because the queue at the restroom was too long in the international departure area), since I've actually missed connecting flights in several countries to bad backups at Immigration and/or Customs.
