Freakish chance, Steve Outing who does a great new media column over at Editor & Publisher just wrote an article on SpamAssassin
including the idea I brought up yesterday about having a service publishers could use to run issues past prior to mailing to make
sure they will not be filtered too badly. I guess great minds think alike.
Anyway, as always Steve's article on the whole spam filtering and delivery problem is well-researched and well worth reading if you
are an email publisher.
