Re: [spf-discuss] spf exp= facility

send me the domain(s) and the email(s) [one that exists one
that dosn't] + examples of passing ip's and some
known-to-fail ip's and i can just simply parse them by hand
or feed to a spf command-line checker and tell you if it
works

Thanks.  That's very generous of you.  I'll send you a
reply off-list.

However, does this mean that there are no well-known
sites using SPF?  That's discouraging :-(

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?

Thanks
