It was recently brought to my attention by another list subscriber that my postings were being flagged by SPF as likely forged. The list postings come from lists.letterrip.com and that's not a server authorized by my SPF entry to send mail for MDCCLXXVI.com. If this list was configured such that each post came From: [email protected], there would probably be no problem with my postings getting through to the SPF 'protected' destination. (Assuming that letterrip.com had SPF entries). I had added an SPF entry to my DNS on the theory that it might prevent my mail from being rejected at various places. Instead, it had just the opposite effect. My guess is that, if a domain HAS an SPF entry, then some servers will flag mail from non-'authorized' servers (such as lists.letterrip.com) as fraudulent. However, in the ABSENCE of SPF entries for a given domain, the mail will not be flagged as fraudulent. Until such time as mail servers at important destinations start rejecting mail because of a lack of SPF entries for the sending domain, it would appear that we are better off *without* SPF entries than with.
