I have the same problem with postfix and MH.
After some searching I finally found the answer. Fedora Core comes with
postfix 2.0.11. In the HISTORY entry for version 2.0.12 there is the
remark:
Bugfix: the stricter postdrop input filter broke "sendmail
-bs". Found by Lutz Jaenicke. File: smtpd/smtpd.c.
and this is exactly the problem.
In other words, if Fedora Core were to upgrade the postfix release to
anything newer than 2.0.11 the bug would disappear. The current release
is 2.0.16.
This particular problem was actually introduced in 2.0.11...
Filed as bug #108960.
