Hi,
Can you help me with score SPF_FAIL=5?
I have a log with information :
Oct 11 16:29:12 mail amavis[30379]: (30379-12) Passed CLEAN {RelayedInbound}, [212.122.192.46]:58179 [5.174.23.34] ESMTP/ESMTP <remote_user@wp.pl> -> <local_user@pbs.edu.pl>, (ESMTP://[212.122.192.46]:58179 < ESMTP://212.77.101.8 < SMTP://5.174.23.34), Queue-ID: 4HSh4l6XNyz339l, Message-ID: <33a042dd91da4801a664bab4698b10fd@grupawp.pl>, mail_id: PIdVdhDdNanD, b: noXf9gHev, Hits: 4.803, size: 5536, queued_as: 4HSh4m1g88z33BN, Subject: "Subject123", From: <remoteuser@wp.pl> (dkim:AUTHOR), User-Agent: GWP-Draft, helo=mx10.utp.edu.pl, Tests: [DKIM_SIGNED=0.1,DKIM_VALID=-0.1,DKIM_VALID_AU=-0.1,DKIM_VALID_EF=-0.1,FREEMAIL_FROM=0.001,HTML_MESSAGE=0.001,SPF_FAIL=5,SPF_HELO_NONE=0.001], autolearn=no autolearn_force=no, autolearnscore=4.803, dkim_i=@wp.pl, dkim_sd=1024a:wp.pl, 289 ms
I use a SPAM Gateway which collects e-mail from the Internet and then forwards it to the iredmail server.
I think my SPAM Gateway is the problem when spf records are checked. I'v added the relay IP address to the whitelist but that didn't fix the problem.

How about lower the score of SPF_FAIL in /etc/mail/spamassassin/local.cf?

Buy me a cup of coffee ($5) to support iRedMail:

Re: SPF_FAIL=5 for domain with correct SPF record

Hi,

I would like to find a reason, not to do a workaround.
Also I can increase overal SPAM score but it is only workaround like  lower the score of SPF_FAIL in /etc/mail/spamassassin/local.cf.
Any other idea why spamassasin is marking that domain SPF_FAIL?

I think that the SPAM Gateway is not the problem, for some domains the SPF_FAIL is active (I'v changed score to 3):
Tests: [DKIM_SIGNED=0.1,DKIM_VALID=-0.1,DKIM_VALID_AU=-0.1,DKIM_VALID_EF=-0.1,FREEMAIL_FORGED_
REPLYTO=2.503,HEADER_FROM_DIFFERENT_DOMAINS=0.249,HTML_MESSAGE=0.001,HTTPS_HTTP_
MISMATCH=0.1,MIME_HTML_ONLY=0.1,SPF_FAIL=3,SPF_HELO_NONE=0.001]

And for other domains there is no SPF_FAIL score:

Tests: [DKIM_INVALID=0.1,DKIM_SIGNED=0.1,HTML_MESSAGE=0.001,SPF_HELO_NONE=0.001,SPF_PASS=-0.001]

Both messages passed through the same SPAM Gateway.

You should check the actual SPF record.
https://www.kitterman.com/spf/validate.html?
and/or

There may be issues with the SPF record for pbs.edu.pl

SPF from pbs.edu.pl results in a PermError, it is their fault, they need to fix their settings

Re: SPF_FAIL=5 for domain with correct SPF record

Hi,
Thank you for the answer.
pbs.edu.pl is my domain, I fixed the spf record, but I think it's not the problem I am asking for.
In my situation, incoming mail comes from wp.pl and many other (not all) domains with a good SPF record are marked with SPF_FAIL = 5.
