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 18.104.22.168 example.com MX 10:mail.example.com example.com TXT "v=spf1 mx ip4:22.214.171.124 -all" mail.example.com A 126.96.36.199 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 firstname.lastname@example.org , and never from email@example.com )
