Removing yourself from SPAM

Spam... it's a killer...
I use Google Mail as authentication and GMAIL Access..
No doubt it is a simple as that.. but on the DNS.. I forgot to add the TXT CODE to deter spam from originated or spoofed from my domain..

So I had to put into place a long line of SPF Records to ensure emails from my domains are not sent out other than being via GMAIL...

azrin.info.  IN TXT "v=spf1 mx a ip4:2404:6800::/32 ip4:172.214.0.0/16 ip4:8.8.0.0/16 ip4:35.184.0.0/13 ip4:64.233.160.0/19 ip4:66.102.0.0/20 ip4:66.249.64.0/19 ip4:70.32.128.0/19 ip4:74.125.0.0/16 ip4:104.132.0.0/23 ip4:172.102.8.0/16 ip4:172.217.0.0/16 ip4:172.253.0.0/16 ip4:173.194.0.0/16 ip4:209.85.128.0/12 ip4:216.58.192.0/16 a:*.gmail.com a:*.gappssmtp.com include:gmail.com"

Darn Long rite?? 
What it means is.. for AZRIN.INFO Allow only Emails sent from SPF Records originating from (Google IP Addresses... so many") and allow emails sent from domains of GMAIL.COM and GAPPSSMTP.COM ... it's Google Apps SMTP Server btw...
Anything else... NO Way.. just delete and bounce.

Good luck to my users using outlook.
