Ahh, the feature you like is
That's not my way. Thats why I did not noticed that.

After Queue Filtering is good for accepting all spam and give most users best chance to become a source of backscatter.

You may setup a 2. smtp server at localhost:anyhighport using a milter.
Then configure your primary smtp server to forward all incoming mail to that 2. smtp server.

That will solve your main problem.
smtp inet n - n - - smtpd
 -o content_filter= inet n - n - - smtpd
 -o smtpd_milters=${opendkim_milter}

now, if the milter fail, the mail still stay in a queue at *your* server.
