I configured a number of spf records using the exp= facility
to provide more details in rejection messages.

I then discovered that the software I'm using to receive
mail (PMDF) doesn't support these.  

That means that the exp= facility doesn't help me on mail
I'm receiving.  But I figured the expanded text could still
be of use to other systems.

The problem is, I don't know how to test to make sure I
haven't make mistakes in creating the referenced TXT RRs.

http://www.openspf.org/Tools suggested mailing to
spf-test(_at_)openspf(_dot_)org(_dot_)  That gets a useful response, but
not one that expands the exp= TXT record.

Is there a suggested system that implements SPF exp=, and to
which I could make a few test connections (manually telnet-
ing to port 25, say) without being impolite?

The spf test address should deal with exp correctly.  If you will email times, 
domains, and what spf record you had published at the time, I will investigate.
