I tried to follow this advice but with no luck.

Could you explain please how to configure those delivery agents smtp1,
smtp2, ... in the same postfix instance?

I tried

postconf -M smtp1/unix="smtp1       unix  -       -       n       -       -
      smtp"
postconf -M smtp2/unix="smtp2       unix  -       -       n       -       -
      smtp"

but then I have an error

postfix                  | Sep 01 08:05:20 test
postfix/trivial-rewrite[190]: error: unsupported dictionary type:
randmap{smtp1

My postfix version is version 3.6.4.
