Because I have not got any answer, I tried trace an internal communication
between postfix'es processes via UNIX-sockets. I discovered that
"trivial-rewrite" only specifies transport or does a canonicalizing.
Process "verify" right tell that recipient address is alias to a
concrete username. If recipient is aliased to more users, all usernames
is announced.
Now I'm trying use "verify" for my business. If simply execute
"verify", it ends with error message in Log "fatal: service verify
requires a process limit of 1".
