SPF "help"

[Chiny]

Is the SPF help correct ?
SPF
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
