Managing Sender Policy Framework (SPF) Records
Tags :SPF Sender Policy Framework email DNS
One of the things a mail administrator must understand is Sender Policy Framework or SPF records in DNS. With the advancement in spam filtering, the ability to verify a server is authorized to send email on a domain's behalf is critical. So I wrote a brief introductory article on SocialBizUG.
SPF allows the owner of an Internet domain to specify which computers are authorized to send mail with sender addresses in that domain, using Domain Name System (DNS) records. Receivers verifying the SPF information in TXT records may reject messages from unauthorized sources before receiving the body of the message. Thus, the principles of operation are similar to those of DNS-based blackhole lists (DNSBL), except that SPF uses the authority delegation scheme of the Domain Name System
SPF works for any mail system so deploying it is a must as some recipients are now requiring entries or they block your email. Read more in the article right here or leave your questions below.
I even have some links in the article to let you validate your new or existing SPF records.
