I've read the man page and says sendmail, purgestat, etc. are supposed =
to be
symlinks to mailwrapper.  In this case, they were discrete files =
differing
in size and content from mailwrapper and those installed by postfix.

I reinstalled usr.bin and usr.sbin from a built world and everything =
works
ok now.  Could this have been the work of some trojan?
