If you are using SpamAssassin simply set the score > for passing SPF tests at a very low non-zero number, say 0.001. That Thats no longer naïvely using.

If anything it seems to work best to score SPF negatively on the grounds that there are two users of SPF - certain big ISPs and spammers, and neither of them usually have much interesting to say ;) Alan -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
