How do I add a TXT record to my domain for SPF?

Assuming my domain is example.com and my mail server is called mail.example.com and my web server is called www.example.com,

I want to add an SPF record to my domain. E.g. "v=spf1 a:mail.example.com -all”

The Server.app is not showing me options to add a TXT record to the domain itself. It only supports this for hosts.

Can I just add one to the file /Library/Server/named/db.example.com? Server.app doesn't overwrite that?

Your right in this case Server.app does not make it possible to add the needed record, here is how to do it.

Launch Server.app
Temporarily turn off the DNS server
Launch Terminal.app
edit /Library/Server/named/db.example.com
insert a line as follows

10800 IN TXT

"v=spf1 a:mail.example.com -all"

Note: The above is your example SPF record and is a very basic one, in reality you might want more options in it.

Then save the changes, and use Server.app to start the DNS server up again.

You have to manually edit the record in a text editor. Just don't reopen the file in the gut after that or you will mess up your changes.

Records live in Library/Server/named

Thanks for the info - this seems to halfway work. My mail server hosting company tells me they see the record but the host name "@" is missing from the TXT record. How can I format that TXT record to include a host name?

TIA
