linux - DKIM : Signature header exists but is not valid -
i have configured postfix spf , dkim emails marked spam.
here domain.db (i use bind9) :
... mail._domainkey in txt ( "v=dkim1; k=rsa; p=abcd" )
i verify :
host -t txt mail._domainkey.domain.com
i receive (ok) :
mail._domainkey.domain.com descriptive text "v=dkim1\; k=rsa\; " "p=abcd"
i've checked problem on email-tester.com, , 10/10, dkim seems correctly installed.
but when check content of email, see :
... dkim:pass dkim:pass spf:pass ... x-spam-report: * -0.0 no_relays informational: message not relayed via smtp * -0.0 no_received informational: message has no received headers * 0.0 t_dkim_invalid dkim-signature header exists not valid x-spam-status: no, score=0.0 required=5.0 tests=no_received,no_relays, t_dkim_invalid autolearn=ham autolearn_force=no version=3.4.0
any idea ?
----- update -------
after adding in master.cf :
-o receive_override_options=no_header_body_checks,no_unknown_recipient_checks,no_milters
here new email content :
... dkim:pass (now there one: ok) spf:pass ... x-spam-report: * -1.0 all_trusted passed through trusted hosts via smtp x-spam-status: no, score=-1.0 required=5.0 tests=all_trusted autolearn=ham autolearn_force=no version=3.4.0
which seems better, email still marked spam, grrr
here's what's going on spf record.
go link , change dns server `google public dns (8.8.8.8)
https://www.unlocktheinbox.com/dnstools/spf/luckeo.fr/
the results of spf v=spf mx ip4:176.58.101.240 ~all
now change dns advantage (156.154.70.1)
the results of spf v=spf1 mx ip4:176.58.101.240 ~all
notice difference v=spf
vs v=spf1
so dns hasn't propagated yet , depending on how receiving email server looks dns records you're running issues. wait 24 hours , if you're still having issues, reply back.
