SOLVED! Thanks to @ZhangHuangbin.
disable_mime_output_conversion = yes in /etc/postfix/main.cf. is the solution.

Now DKIM verifications pass when sendingg mails via The bat! mail client.

Little update work in progress but..

- mail sending by email client the bat! (www dot ritlabs dot com) did not pass DKIM veryfication. No matter of version 9.x or 12.x DKIM failed

- mail sending by email client Thunderbird - dkim pass .

SMTP settings are the same.

Please login to EE as global admin, then:

- Click "Server Settings" -> "Spam Policy", make sure option "Prefix text [SPAM] to the subject of spam" is NOT enabled.
- Go to domain profile, click "Spam Policy", make sure option "Prefix text [SPAM] to the subject of spam" is NOT enabled.

Then send a testing email to verify DKIM signature.

- After published DNS record, click the `Refresh` button to check DKIM status.
By the way, better use the ticket system on iRedMail Store website for EE questions:

On admin panel, domain section is DNS button, there DKIM options for generate and validate DKIM DNS. When i used this "tool" i have issue with dkim validation domain and amavisd testkeys failed.

When using amavisd for generate dkim, puting dkim key to DNS record, amavisd testkeys pass but on admin panel, domain section, DKIM not matched with DNS record (generated by amavisd).

So, what should i do, to match amavisd DKIM, admin panel to show and generate correct DKIM keys ?
No manuals for iredmail EE found...

Ps. mail are generate wrong with DKIM..
