DKIM / DMARC with PMTA and MailWizz

I am trying to configure DKIM with Mailwizz and I have not gotten
My sender domain is maodeals.com and my installation domain is maosender.com

I have generated a private key in:
https://www.port25.com/support/domainkeysdkim-wizard/
And insert in etc/pmta/default.maodeals.com.pem
And the public key in TXT DNS in plesk:
mailer._domainkey.maodeals.com. TXT v=DKIM1; r=bounces; g=*; k=rsa; p=k=rsa; p=(public key)

In mailwizz I have these options
DKIM Signing: NO
Verifies: YES

In www.mail-tester.com say that I have 2 DKIM signatures and in Gmail say:
Authentication-Results: mx.google.com;
dkim=temperror (no key for signature) header.i=@maodeals.com;
dkim=fail header.i=@maodeals.com;
spf=pass (google.com: domain of bounces@maodeals.com designates 194.140.137.219 as permitted sender) smtp.mailfrom=bounces@maodeals.com;
dmarc=pass (p=NONE dis=NONE) header.from=maodeals.com
DKIM-Signature: v=1; a=rsa-sha1; c=relaxed/relaxed; s=default; d=maodeals.com;
h=Message-ID:Date:Subject:From:Reply-To:To:MIME-Version:Content-Type; i=carla@maodeals.com;
bh=rDT59fpkOM2052+sv7HErP7eq+4=;
b=Q2Mx3/3JtlsP49KuYpM/wxAbhR9C39H8TN3TSnlDt/IumxvcnNdDkGvEm6Ma/g4jGylDpbWcDzAo
MhWHr90IkAtDuRXhGJnt/RthExU1TdaqJeHVGKTdAHppu3Tsdqaah1dnhq0nmOdr9n3PIRir0wWF
rttCzirS6R7oq+v83mA=

but I have only one DKIM

I always have an error in DKIM. I've tried about 30 times. It seems that public and private signature do not match and do not understand.

Need help, please.

And DMARC message is:

Tu mensaje falló la verificación DMARC
key not found

Verification details:

  • mail-tester.com; dmarc=none header.from=maodeals.com
  • mail-tester.com; dkim=permerror reason="key not found" header.d=maodeals.com header.i=carla@maodeals.com header.b=kbZy4iZC; dkim-adsp=none (unprotected policy); dkim-atps=neutral

Hi There,

Looks like you missed to specify "selector" for your DKIM key in your pmta config (domain-key selector,domain.com, <key file>). As per your DNS settings, your selector should be "mailer". Specify the selector correctly, reload config and try again.

Also, for test purpose, make the DNS entry simple - mailer._domainkey.maodeals.com. TXT v=DKIM1; k=rsa; p=(public key) - would do. Check the syntax here : http://dkimcore.org/c/keycheck
