Allan Wallace - SPF
What is SPF?
SPF - or to give it the full title of "Sender Policy Framework" is an extremely good idea.
If you have an internet domain (such as allanwallace.co.uk) then you really, really should have an SPF record.
Why should I have an SPF record?
What does an SPF record do?
The reasons why you should have an SPF record, include the following:
• A strict SPF record configured correctly helps you prove your emails are genuine.
• A strict SPF record configured correctly helps you prove fake emails are fake.
• A strict SPF record configured correctly helps protect the reputation of your domain name, which also helps to .
• A strict SPF record configured correctly helps prevent the propagation of viruses from email addresses that pretend to use your domain name.
• A strict SPF record configured correctly helps prevent the propagation of SPAM from email addresses that pretend to use your domain name.
• A strict SPF record configured correctly helps protect people from "Phishing" scams.
If you work in I.T., and you are currently working to clear up the damage caused by Cryptesla, Cryptolocker, CryptoWall, TeslaCrypt, or some similar encrypting malware that arrived in a
customer's email, appearing to be genuine, you soon start the understand why an SPF record is a good idea.
If you do not work in I.T., but are sick of receiving SPAM after SPAM after SPAM, and you learn that a strict SPF record could greatly reduce the amount of SPAM you receive, you start to
appreciate why a strict SPF is a good thing.
If you received an email that appears to be from your bank, and then later discover it was fake, and thousands of pounds / dollars / euro have disappeared from your bank account without
warning, you may also start to appreciate why strict SPF records are a good idea.
Sadly, despite the fact that it has been more than a decade since SPF records were first recommended, many organisations and individuals who have domain names (the part of your
email address after the @ symbol) either do not have an SPF record, or worse, do not have a strict SPF record, and this can lead to all of the above problems.
When I look at my life working in I.T., In an average year I spend I probably spend close to 80 hours cleaning up malware and viruses that have been infected by email attachments.
I want this to stop.
You should too.
