Thanks Scott, I did just work this out and was about to post back to the list when I read your reply.

Even >though 62.128.191.26 has a reverse ending in directpceu.com The catch here is a technicality of SPF, where it won't allow the "ptr:" to pass if the PTR record matches, but has no A record pointing back to the same IP. So in this case, relay03-1.direcpceu.com does contain "direcpceu.com", but since relay03-1.direcpceu.com does not have an A record, it doesn't pass the test. -Scott --- Declude JunkMail: The advanced anti-spam solution for IMail mailservers since 2000.
