DKIM / DMARC with PMTA and MailWizz


New Member
I am trying to configure DKIM with Mailwizz and I have not gotten
My sender domain is and my installation domain is

I have generated a private key in:
And insert in etc/pmta/
And the public key in TXT DNS in plesk: 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 say that I have 2 DKIM signatures and in Gmail say:
dkim=temperror (no key for signature);
spf=pass ( domain of designates as permitted sender);
dmarc=pass (p=NONE dis=NONE)
DKIM-Signature: v=1; a=rsa-sha1; c=relaxed/relaxed; s=default;;

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:

  •; dmarc=none
  •; dkim=permerror reason="key not found" 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,, <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 - TXT v=DKIM1; k=rsa; p=(public key) - would do. Check the syntax here :
