Using SPF

[timtrott]

The SPF section in PSA 8.x.x provides simple definitions of the various SPF application options. Can anyone offer advice/experience with what choices work best?

Thanks for the reply--- I'm fairly familiar with SPF, but I was really asking which of the setting levels in Plesk 8.1 are the most effective?

 

[Eraser]

so I can ask you ;-)

Where do I have to enter the generated SPF text of 'openspf.org'?

in
domain -> DNS -> TXT

or

server -> mail -> SPF protection?

 

[timtrott]

...in domain -> DNS -> TXT

See the example provided at http://www.dnsstuff.com

In the control panel (Server -> Mail) you may select the level of SPF implementation.

--Never Block
--Temporary error notice
--Reject when resolves to "fail" (this is my current setting)
--Reject when resolves to "soft fail"
--Reject when resolves to "neutral"
--Reject when not resolve to "pass"

Is it correct if I use the domain mail.foo.com or do I have to take www.foo.com or anything else for entering the TXT values?

 

[timtrott]

If your server is foo.com and your hosted domains use the foo.com mail server, then the text line in your default DNS would read:

<domain>. TXT v=spf1 a mx ptr include:foo.com ~all

and the DNS for all hosted domains would have a corresponding TXT DNS entry:

hostedSite.com TXT v=spf1 a mx ptr include:foo.com ~all

You should add it to the default DNS in the Server CP and then manually apply it to the DNS record of currently hosted domains.
