If you are creating the SPF record you will likely see a form with at least two fields, they are: “Host” or “Name” and “Value”.
Here is what you enter under those fields:
(Yes, you put the @ symbol under the host or name category. @ means that the record is pointed at your own domain. Some editors will require the “@” symbol, some will require you to enter your own domain, and others will not let you enter anything. Every DNS Editor is different – you may need to contact your hosting provider for information on how to enter this record correctly).
Value: v=spf1 a mx include:ariticmailmta.com ~all
Check to see if there are any other SPF records in your domain’s DNS. There can only be one SPF record per domain, so if there is an existing record just add include:ariticmailmta.com to that record.
For example, if your domain already has the record:
v=spf1 a mx include:_spf.google.com ~all
….then you would just add:
The final record would look like this:
v=spf1 a mx include:_spf.google.com include:ariticmailmta.com ~all
