Please can someone assist me in creating a SPF record for my domain, ttaf.co.za.
I am running a hybrid environment. All email gets enters my org through my IronPort cluster however sending email is different.
On prem users route their email through my IronPorts. My O365 users send mail directly to the internet.
My MX records are 220.127.116.11 and 79.
This is what i got so far using http://www.spfwizard.net/
ttaf.co.za. IN TXT "v=spf1 mx a ip4:18.104.22.168/31 a:spf.protection.outlook.com include:ttafcoza.onmicrosoft.com -all"
is that correct?
