When sending an email to one of my client I am receiving bounce back email with following statement.

What is SPF ?
Sender Policy Framework is a record that is used to help prevent email spoofing. It allows you to specify all of the IP addresses that you would send mail from in one simple TXT record, and to tell the receiving server to only allow the outbound servers you listed.

We suggest that you create a Sender Policy Framework (SPF) record for your domain.
The purpose of an SPF record is to prevent spammers from sending messages, Recipients can refer to the SPF record to determine whether a message from your domain comes from an authorized mail server.

For example, suppose that your domain uses Gmail. You create an SPF record that identifies the Google Apps mail servers as the authorized mail servers for your domain. When a recipient's mail server receives a message from, it can check the SPF record for to determine whether it is a valid message. If the message comes from a server other than the Google Apps mail servers listed in the SPF record, the recipient's mail server can reject it as spam.

How to set SPF ?


Mechanisms can be prefixed with one of four qualifiers:

"+"   Pass
"-"   Fail
"~"   SoftFail
"?"   Neutral


"v=spf1 mx -all"

Allow domain's MXes to send mail for the domain, prohibit all others.
"v=spf1 -all"

The domain sends no mail at all.
"v=spf1 +all"

The domain owner thinks that SPF is useless and/or doesn't care.
