OK. I implemented SPF on my Postfix mail server and published SPF records for dirac.org and wavefunction.org. It was actually pretty easy. Also redid/re-evaluated my entire Postfix main.cf anti-UCE section. Added some extra anti-UCE guards I didn't have in there before. All in all a productive day. _______________________________________________ vox-tech mailing list [email protected] http://lists.lugod.org/mailman/listinfo/vox-tech
