No, but you if you can describe what you did, with some specificity,
showing configuration and logs, someone will probably help.

Likely issues:
* Your submission "smtpd" in master.cf does not set the right
milter macros. See the stock master.cf file:
https://github.com/vdukhovni/postfix/blob/master/postfix/conf/master.cf#L19-L35
* You have not correctly (or at all) configured a DKIM signing milter.
The milter needs access to the private key corresponding to the
correct "selector", as published in your DNS.
Do you really need DKIM? I get by without it.
