I am maintaining the DNS records of a domain which was set up by someone else.

I have following RRs (visible in an webinterface):

example.com A
example.com MX 10:mail.example.com
example.com TXT "v=spf1 mx ip4: -all"

mail.example.com A
mail.example.com TXT "v=spf1 include:example.com"

Is it correct that I can remove the SPF TXT record of mail.example.com ? As far as I know, it is not necessary. (Assuming that eMails are sent from xxx@example.com , and never from xxx@mail.example.com )


Yes, you can remove the TXT record for mail.example.com.

    Consider using TXT "v=spf1 -all" rather then not having one completely. – Drifter104 Jun 5 '15 at 13:59
