Custom Domain email setup

 


It's taken me a while, but I have finally got my email and domain setup correctly to support all the new  DMARC standards in place. 


I used many services to check but Learn and Test DMARC (learndmarc.com) was by far the most entertaining and informative.


DMARC Results


--- Connection parameters ---

Source IP address: 0.0.0.0

Hostname: example1.com

Sender: user@example2.com


--- SPF ---

RFC5321.MailFrom domain: example2.com

Auth Result: PASS

DMARC Alignment: PASS


--- DKIM ---

Domain: example2.com

Selector: sig1

Algorithm: n/a

Auth Result: PASS

DMARC Alignment: PASS


--- DMARC ---

RFC5322.From domain: example2.com

Policy (p=): quarantine

SPF: PASS

DKIM: PASS

DMARC Result: PASS


--- Final verdict ---

DMARC does not take any specific action regarding message delivery. Generally, this means that the message will be successfully delivered. However, it's important to note that other factors like spam filters can still reject or quarantine a message.

Microsoft outlook.com and Personal domain email forwarding

Microsoft outlook.com and Personal domain email forwarding

It seems the Outlook redirect rule stopped working; Access denied ,does not pass DMARC verification

"All redirected mails bounce back with "Access denied, sending domain [DOMAIN] does not pass DMARC verification and has a DMARC policy of reject.

for example:

Your message wasn't delivered because the recipient's email provider rejected it.

DB5EUR02FT022.mail.protection.outlook.com gave this error:

Access denied, sending domain [SENDCLOUD.COM] does not pass DMARC verification and has a DMARC policy of reject. [PAXPR03MB8202.eurprd03.prod.outlook.com 2023-05-10T13:59:59.883Z 08DB4F6AA79E53B4] [DUZPR01CA0068.eurprd01.prod.exchangelabs.com 2023-05-10T13:59:59.889Z 08DB50E6414EAB05] [DB5EUR02FT022.eop-EUR02.prod.protection.outlook.com 2023-05-10T13:59:59.879Z 08DB513EAF6E0C11]"

I have this personal domain email forwarding to my @outlook.com address is now generating these "errors" about 1 in 5 emails. Seems nothing more I can do. Apart from move away from outlook.com 

Thanks Microsoft
