I'm a bit lost

I configured DKIM, I did this:

Over the panel:
(1) Email - DKIM & SPF Manager

(2) I selected my domain and i generated a DKIM key

(3) Then i took a look at: "/var/named/my_domain.com.db" and i found:
default._domainkey IN TXT "v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDyPJGm1OFopzv9zfPm7DQfQP4CDSe1iNS0BAogvXqaX/viXOVgMDJmra2FaCm2h4BE3XNLBEhaR+iap3GwFCuRNM3EihL6RlpIT6zxUl4CDQSY0Mu3vCDcV59ycWoQvebanqQPKwU1fHH6dZkq22/ncwxW/rUENke2qXKLxybkrwIDAQAB"

(4) Then i went to DynaDot (my dns provider) and i added the TXT record
DOMAIN: default._domainkey.my_domain.com
TARGET:
v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDyPJGm1OFopzv9zfPm7DQfQP4CDSe1iNS0BAogvXqaX/viXOVgMDJmra2FaCm2h4BE3XNLBEhaR+iap3GwFCuRNM3EihL6RlpIT6zxUl4CDQSY0Mu3vCDcV59ycWoQvebanqQPKwU1fHH6dZkq22/ncwxW/rUENke2qXKLxybkrwIDAQAB

I sent an email over roundcube to gmail but it's still not signed, what did i miss?
What else should i do?

Thanks for your time

Hi,

Had same problem but there are missing some config details in postfix to sign mail.
Try this:

Edit file:

/etc/postfix/main.cf

Add this at the end of file:

smtpd_milters           = inet:127.0.0.1:8891
non_smtpd_milters   = $smtpd_milters
milter_default_action   = accept
milter_protocol         = 2

save file and restart postfix.

I take this from some online tutorial and works for me... But dont know did they fixed owner permissions for DKIM I allready reported this bug!
But this fix must work for new added domains..

Try and let us know

Regards

I'll take a look, thanks for your help buddy

try rebuilding mail server with DKIM it should resolve the issue.

It worked with the zakrpa tip.
I'm too scared to rebuild mail server, it might stop working like happened before, i had to do it over and over 

new rebuilder has this fix included so you don't need to manually edit configuration files.

In your domain panel, the TXT record Host should be

default._domainkey.my_domain.com  (remove --> .my_domain.com)

The VALUE should be

v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDyPJGm1OFopzv9zfPm7DQfQP4CDSe1iNS0BAogvXqaX/viXOVgMDJmra2FaCm2h4BE3XNLBEhaR+iap3GwFCuRNM3EihL6RlpIT6zxUl4CDQSY0Mu3vCDcV59ycWoQvebanqQPKwU1fHH6dZkq22/ncwxW/rUENke2qXKLxybkrwIDAQAB
