escaped >From hides Subject from Solaris-2.5 mailx

Hello,

Some of our users prefer /usr/ucb/mailx on our Solaris 2.5
machines (with NFS mounted mail spool) and we have recently
found the Subject: info doesn't show up when the message has
an escaped >From line.  Like this,

  From garyare(_at_)are2(_dot_)berkeley(_dot_)edu  Thu Dec 12 20:18:53 1996
  >From garyare  Thu Dec 12 20:18:53 1996

I don't understand why procmail (apparently) adds the extra >From line.
Can anyone point me in the right direction?

The rest of this message is my attempt to include enough information
for one of you gurus to see whats happening.

Here is the disappearing Subject act:

 % mailx -f garyare
   mailx version 5.0 Wed Oct 25 04:12:43 PDT 1995  Type ? for help.
   >O  1 garyare(_at_)are2(_dot_)berke Thu Dec 12 20:18   17/849   

compare with elm's frm output:
 % frm  garyare
   Gary Casterline      Yes, there is a subject here

If I delete the >From line then mailx will display the Subject. 

Here are the FEATURE lines from the sendmail 8.8.4 m4 file:
        FEATURE(allmasquerade)dnl
        FEATURE(always_add_domain)dnl
        FEATURE(smrsh)dnl
        FEATURE(local_procmail)dnl

Which generates the following in the sendmail.cf:

        Mlocal,         P=/usr/local/bin/procmail,
                        F=lsDFMAw5:/|@qSPfhn9, S=10/30, R=20/40,
                        T=DNS/RFC822/X-Unix,
                        A=procmail -Y -a $h -d $u
        Mprog,          P=/usr/local/etc/smrsh,
                        F=lsDFMoqeu9, S=10/30, R=20/40, D=$z:/,
                        T=X-Unix,
                        A=sh -c $u

!!procmail -v

What have I forgotten?
Thanks for any help.
