SPF – Sender Policy Framework an Antispam solution

The Email Administrator has to implement SPF filtering on the mail servers and create SPF records for your mail server. SPF is the acronym for Sender Policy Framework and is an open standard specifying a technical method to prevent sender address forgery. SPF protects the envelope sender address giving the opportunity for a mail server to check if an email message is originating from a valid source and not from a forged source.
The technology requires two sides configuration:
(1) The domain owner publishes an SPF record in the domain’s DNS zone.
(2) The receiving server checks the message against the SPF record policy in the DNS zone.
The receiving mail server then can accept or reject the message based on the compliance with the domain’s stated policy. If the message comes from an unknown server, it can be considered a fake.
The SPF will help tremendously against spoofing. Email Spoofing means faking the source of an email message so that it appears as coming from a different source. This will avoid a lot of messages that appear to come from your address but you never sent. More about spoofing on this Wikipedia article: http://en.wikipedia.org/wiki/E-mail_spoofing
