Sure but this is only _one_ hard-coded transport and not one I can
dynamically change like in the tcp_table lookup.

So it looks like as if the logic tries to minimize the lookup queries
and expect all tables which are more than a key=value mapping
knows with _one_ query if it is responsible or not.

That means I can't use static hash tables for domains if I want to have
a tcp table which gives me a default value if _no other hash based_
table has a domain hit.

Correct me if I'm wrong.

  x...@yyy.com and yo the tcp table has to know all domains as well if it

transport_maps can use hash tables AND tcp tables. transport_maps
queries each table in the specified order, and stops when a result
is found. When no result is found, Postfix uses default_transport.

No. x...@domain1.tld matches the first line in /etc/postfix/transport.

You seem terminally confused about how maps are used.
Each map type has specific documentation on how it is queried, but no 
map determines WHEN it is queried. You define that in transport_maps.

That's not how it works in my 2.9 postfix version.. trivial-rewrite is
doing the following (regarding to -vv logs):

1. search for x...@domain1.tld

  1. in transport which has NO match
  2. asking the tcp_table which HAS a match

so this wouldn't work.. but if I would change the random.rb that is
only giving a 200 smtp{1..3}: if the request is for a domain and
not for the full email address the following will happen:

1. search for x...@domain1.tld

  1. in transport which has NO match
  2. asking the tcp_table which has NO match because it is a full
 address

2. search for domain1.tld

  1. in transport which HAS a match = correct transport is used

but now.. if I want to send a mail to y...@domain2013.tld this will
happen:

1. search for y...@domain2013.tld

  1. in transport which has NO match
  2. asking the tcp_table which has NO match because it is a full
 address

2. search for domain2013.tld

  1. in transport which has NO match
  - now postfix is using the default_transport because tcp table is
only asked once and not a second time (see tcp_table(5))

So it looks not good for me, isn't it?

 I know. But replace it with whatever logic you want as a last resort if
 no other transport_map maps a _complete mail_ or a _domain_.

If you want the TCP map reply to depend on the result of ``line =
STDIN.readline'', then you need to write code that produces that
response.

As documented in transport(5), The special query for * asks for
a wild-card result. It does not matter for your configuration.

Also in transport(5):

TCP-BASED TABLES
   This section describes how the table lookups change  when  lookups  are
   directed   to  a  TCP-based  server.  For  a  description  of  the  TCP
   client/server lookup protocol, see tcp_table(5).  This feature  is  not
   available up to and including Postfix version 2.4.

   Each  lookup  operation  uses the entire recipient address once.  Thus,
   some.domain.hierarchy is not looked up via its parent domains,  nor  is
   user+foo@domain looked up as user@domain.

   Results are the same as with indexed file lookups.
