Dear Maintainer, The SPF testing program "spfquery" in its result gives a reference link for further info but which is an old URL ( www.openspf.org ) that's no more active and has been replaced by a new URL ( www.open-spf.org ). Ie. a user who got this message and is then going to the said old link gets an error. The program should be recompiled after fixing that address in the source code..
