Hello!
I recently have got several complains about spam incoming. Analyzing these mails i have found that they are lacking DKIM signature at all and in PMG logs i couldn't see evaluation of this.

Log excerpt for mail that have DMARC policy to none, fail SPF with permerror
Code:
Received-SPF: permerror (linkreit.com: Redundant applicable 'v=spf1' sender policies found) receiver=pmg.example.com; identity=mailfrom; envelope-from="jobs@linkreit.com"; helo=physics1.physics.pub.ro; client-ip=141.85.216.3
and has no DKIM signature presented
Code:
SA score=2/5 time=0.686 bayes=0.55 autolearn=no autolearn_force=no hits=BAYES_50(0.8),DMARC_NONE(0.1),GB_GEN_REDIR_URL(0.5),HTML_MESSAGE(0.001),HTML_MIME_NO_HTML_TAG(0.377),KAM_DMARC_NONE(0.25),KAM_DMARC_STATUS(0.01),MIME_HTML_ONLY(0.1),SPF_HELO_NONE(0.001),SUBJ_ALL_CAPS(0.5),T_SCC_BODY_TEXT_LINE(-0.01),T_SPF_PERMERROR(0.01)
PMG tuning near to default.

Is there any reason that mail coming without signature does not get at least 1 spam point? I thought that such messages are primary suspects.
