SPF Records
Created on 2020-10-03T23:54:48+00:00
A TXT record you need to add to your DNS. It lists the IP addresses which are allowed to send e-mails on your behalf.
v=spf1 a mx ip4:10.0.0.1 ~all
- ip4: an IPv4 address
- ip6: an IPv6 address
i don't know what ~all does; something about allowing all addresses in the record.
