=DMARC=
Adding a DMARC DNS record is optional, but can be beneficial.
There are various online generators for creating a dmarc record, but the contents of the record will cover the following settings:
* 'v' - The version - usually DMARC1
* 'p' - What to happen if dmarc fails, eg none, quarantine, reject
* 'rua' - an email address (or multiple comma separated addresses) of where you'd like to receive reports
* 'ruf' - an email address (or multiple comma separated addresses) where you'd line to receive individual failure reports
The rua and ruf will be used by some of the bigger email providers - eg gmail, outlook, yahoo.
We'd suggest initially setting up reporting but no rejecting so that you can see how it's working out.
And example dmarc record which would send you reports but not tell other email severs to block if a message fails DKIM would look like this:
Host: _dmarc
Type: TXT
Value: v=DMARC1; p=none; rua=mailto:YOU@YOURDOMAIN.COM; ruf=mailto:YOU@YOURDOMAIN.COM; fo=1
