SPF Record

[MatthewL]

Not sure if this is the right area so feel free to move it.

 

I have my SPF record in and working but if I send from that account not on my Office 365 the messages still gets through although the FAIL appears in the header. I thought having the SPF record in place was to amongst other things to stop messages been sent from other none approved sources?

Hi Matthew,

 

The SPF record will still allow the email to be sent, however it is designed to inform the recipients mail provider to mark it as junk/spam/phishing etc.

 

I'm not sure why it is displaying "FAIL", try sending it to another recipient, who has a different email provider (I.e. Somebody who has a gmail account) and see what happens.

It's only in the header is shows it as a fail which is how I think its marked as junk/spam/phishing.

 

It's quite new to me so thought it just dumped it.

An SPF record just tells the world what IPs the domains email servers use. You will need to amend your SPF record to include whatever SMTP server is missing.

Have you used an spf testing site? I had to trial and error the SPF record until I got a success. In the end it was something like not having the server I expected in the record.

Well there's plenty of tools out there for testing and generating the SPF records. I use SPFWizard for my records.

 

SPF Wizard - SPF Generator DNS tool

Yep, I think that was the one I used.

All as should be, need to look further into this I think.

v=spf1 ipv4:xxxx.xxxx.xxxx.xxxx ipv4:xxxx.xxxx.xxxx.xxxx include:spf.protection.outlook.com -all

 

Run a NSLOOKUP on your MX servers in your DNS settings and add the IPs, For example:

 

v=spf1 ipv4:10.20.30.40 ipv4:101.102.103.104 include:spf.protection.outlook.com -all
