If your incoming mail has suddenly started failing....

[HostaHost]

spf.trusted-forwarder.org has disappeared from DNS, and by default, Plesk 8 and 9 had an include:spf.trustedforwarder.org in the SPF rules. So, if you had enabled SPF checking on your Plesk 8 or 9 server, your incoming mail is likely being affected right now. Just delete that from the spf rules and it will go back to normal.

Does anyone on here know if trusted-forwarder.org has disappeared permanently or is this a temporary issue, and what the impact is for SPF in general?

I'm not sure what its purpose was to begin with but there's no impact from removing it.

Although my server with Plesk 11.0.9 doesn´t have "spf.trusted-forwarder.org" configured, I still see it in the log files. Any idea where this may come frome?

I have seen another thread and that user experienced the same. Seems to have been fixed by appyling a patch, but as that thread is from 2010 I would have expected that patch to already be included in Plesk 11.0.9.

You'll want to look in two places:

/var/qmail/control/spfrules

or

/etc/psa-spf/spfrules

If you don't do any inclusions, just empty that file; i.e. cp /dev/null /etc/psa-spf/spfrules

Thx! =)
"/var/qmail/control/spfrules" doesn´t exist, but I found it in "/etc/psa-spf/spfrules".
