The postfix RPM supplies smtp-source and smtp-sink, but omits their corresponding man pages....
Thanks for the sharp eyes! Fixed in postfix-2.0.18-1 which should be in FC2 BTW, this caused me to notice that qmqp-sink & qmqp-soruce were missing as well. For reasons I don't understand qmqp-sink is not build into bin like the others and qmqp performance measuring does not seem widely useful (right?) So at the moment the rpm does not include the qmqp benchmark tools and I assume thats fine.
Thanks! Omitting the qmqp-* stuff is probably fine -- that's AFAIK only useful when trying to do dual qmail / postfix installs
