Impact of enabling DKIM and DMARC

[saikelu]

Hi ,

We are planning to enable DKIM and DMARC in our tenant (SPF is already inplace). We are planning to start with DMARC policy as none as we have third party senders using our domain.

Will there be any impact on email delivery even if we are using the DMARC policy as none ?

Regards,

There is no impact as long as you set DMARC policy as none.

The only mails will be dropped, are the emails that are edited in transit, which makes the email invalid.
