I use mail/dkimproxy on FreeBSD and it works great. I followed the config 
template on 
https://poolp.org/posts/2018-05-21/switching-to-opensmtpd-new-config/ and it 
was very simple and straightforward.

Did you ever figure this out? I'm having the same issue. I have a linux system 
with Logwatch set to e-mail 'root', and the root user has a ~/.forward to a 
fully qualified e-mail address (u...@example.com). It only started happening on 
June 11, when I upgraded opensmtpd from 6.6.4,1 -> 6.7.1,1 (on my mailserver, 
which is FreeBSD). I get the same "ORCPT address syntax error" you're seeing. 
Here's the log from smtp when it happened yesterday:

Jul 10 03:19:03 roast smtpd[80856]: 66aa64942b25c1fd smtp failed-command 
command="RCPT TO: ORCPT=rfc822;root" result="553 ORCPT 
address syntax error"

The linux system hasn't been changed in years, and it started happening 
immediately after the upgrade of opensmtpd, so I imagine it's related to that.
