I'm engaging you in a bit of self-education really.  If Fedora switched
back to Sendmail, it's news to me, and kind of horrific news at that.  I
can't speak for the OP, but problems with "postdrop", wherever he saw
this, is a pretty good indicator that he's running Postfix.

Any chance you specifically asked for Sendmail when you did your install?

Also, MTAs do not play nice together willingly (even if it's multiple
instances of the same one).   Take it from someone who's run three of
them on the same server.  If there's a distro that knows how to handle
multiple MTAs, I'd also like to hear about that, so it's a pretty safe
bet that you have one, and only one installed.
