dkimproxy listens on localhost:10121, and ships a postfix-conf.d-snippet
which instructs postfix to send mail to localhost:10121 and receive it
back on localhost:10122.

amavis listens on localhost:10211, and ships a postfix-conf.d-snippet
which instructs postfix to send mail to localhost:10211 and receive it
back on localhost:10212.

Bot postfix-conf.d-snippets are concatenated, that's it.
postfix ships to localhost:10121 first, gets it back on 10122, ships it
to localhost:10211, gets it back on 10212, and delivers it.
Everything that package-maintainers had to do is to make sure their
port-pairs don't collide with other packages - and to agree on some
useful conf.d-snippet ordering, of course.
As I said, I don't know if this would be possible with current postfix
at all even if we'd implement conf.d-snippets on our own.
sendmail milters can be and are combined that way, one "just" have to
make sure to merge the milter-macro definitions correctly.

That's exactly the small performance drop as price paid for a straight
and clean configuration.
