SPF DNS Entry
Traxel Settings
- IPV4: 69.10.40.10
- IPV6: fe80::d227:88ff:fe34:7999/64
- Format: v=spf1 ip4:40.113.200.201 ip6:2001:db8:85a3:8d3:1319:8a2e:370:7348 include:thirdpartydomain.com ~all
- Start with the SPF version, v=spf1.
- Indicates that this is an SPF record.
- Will always be spf1 as other SPF versions have been discontinued.
- We'll only ever need 640K of RAM.
- Next, all IP addresses that are eligible to send email on behalf of your domain.
- Space delimited
- prefix ip[n]:
- ip4:69.10.40.10 ip6:fe80::d227:88ff:fe34:7999
- Next comes the include statement, which lists every third party organization that sends email on your behalf.
- Does this mean interserver? Is this the part where reverse lookups come in?
- include:thirdpartydomain.com
