If you do not currently have a DMARC record, then one needs to be added to your domain's DNS. If you do not know who your DNS provider is, it is usually the provider that you registered the domain name with.
The following provides instructions on how to add our recommended starter record for some of the most common DNS providers:
If your DNS provider is not listed above, there should be some information in their knowledgebase/help-articles on how to add a TXT record using their interface. You can then use the details below to add the record.
If you have an IT administrator/support-team that looks after your domain/website/infrastructure you will need to ask them to add the record for you, using the details below.
_dmarc.yourdomain.com 60 TXT "v=DMARC1; p=none; rua=mailto:rua-import-xxxx@sendforensics.com"
This is an example of the recommended starter record, where rua-import-xxxx@sendforensics.com is your unique DMARC RUA analysis address. Your particular starter record can be found in DMARC data section of Domain Settings for your domain.
_dmarc.yourdomain.com
Host i.e. the name of the DMARC record and which domain it applies to
60
TTL or Time To Live (how quickly the DNS record updates upon change). This is a 60 second TTL, but you can usually leave this to your provider's default setting.
TXT
The type of DNS record. DMARC uses TXT
v=DMARC1
The DMARC version being used - this is mandatory and has to come first
p=none
The DMARC policy for what a receiving-server should do with a failed email (here, it's saying "do nothing" which is the safest to start with but offers none of the protection or extra deliverability benefits of an enforcement policy) - this is also mandatory and has to come after the version
rua=mailto:rua-import-xxxx@sendforensics.com
This tells the receiving-server to send a report of the transaction to our system for processing and analysis (note that there is no personally-identifiable information contained in these reports).
