SPF "help"

Post by Chiny » Tue Jan 24, 2017 3:06 am

Is the SPF help correct ?
If your domain uses SPF you can add "include:a._spf.rollernet.us" to authorize our Outbound Mail service as a valid mail source.

Using that record, I get mail trashed; changing it to smtpauth.rollernet.us corrects the problem.

It's correct. You can validate it with an external tool such as: http://www.kitterman.com/spf/validate.html

For example, we use it in our own domain rollernet.us:

Code: Select all

; <<>> DiG 9.9.5-9+deb8u11-Debian <<>> -t TXT rollernet.us
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 13635
;; flags: qr rd ra; QUERY: 1, ANSWER: 2, AUTHORITY: 0, ADDITIONAL: 0

;rollernet.us.			IN	TXT

rollernet.us.		85075	IN	TXT	"v=spf1 include:whiskers.rollernet.us include:a._spf.rollernet.us include:opensrs.spf.rollernet.us ~all"
