I'm not even sure that you can actually do it with the current Sendmail 
milter interface.  I'm not aware of a way to do it, but I haven't read 
any documentation on it in quite some time.

Sendmail milter prior to 8.13 provided for appending headers only with
smfi_addheader.  Beginning with 8.13.0, the milter api adds the
smfi_insheader call.

If this is happening, or starts to happen, I'd probably implement 
re-using the Received-SPF headers (where appropriate) pretty quickly.

Pymilter prepends the Received-SPF header as required when running with
an 8.13 version of sendmail.  For instance, here I copy and paste
these adjacent header fields from your post:

Received-SPF: pass (mail.bmsi.com: domain of v2.listbox.com designates
    207.8.214.5 as permitted sender) client-ip=207.8.214.5;
    
envelope-from=listbox+trampoline+735+975880+f4753d05(_at_)v2(_dot_)listbox(_dot_)com;
    helo=apex.listbox.com; receiver=mail.bmsi.com; identity=mailfrom;
Received: from apex.listbox.com (apex.listbox.com [207.8.214.5])
        by mail.bmsi.com (8.13.6/8.13.6) with ESMTP id kAB6QpoY009230
        for <stuart(_at_)bmsi(_dot_)com>; Sat, 11 Nov 2006 01:26:51 -0500

BTW, I just noticed that the RFC shows the Received-SPF result as camel cased,
i.e. "Pass" instead of "pass".  Is this important?
