I have a domain split on two postfix servers.  The secondary (not the default) 
hosts only a few email accounts so I added them to the transport map:

off...@domainchanged.com      dovecot:
o...@domainchanged.com        dovecot:
reu...@domainchanged.com      dovecot:
...

This works for local delivery and accepts email from the primary server just 
fine.  However, when using this secondary server for relaying to accounts 
hosted on the primary the delivery fails:

# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.localdomain.
Escape character is '^]'.
220 imail.domainchanged.com ESMTP Postfix (Debian/GNU)
helo kosmosisland.com
250 imail.domainchanged.com
mail from:da...@kosmosisland.com
250 2.1.0 Ok
rcpt to:t...@domainchanged.com
550 5.1.1 <t...@domainchanged.com>: Recipient address rejected: User unknown 
in virtual mailbox table

So I added to the transport table at the end:

*                           smtp:[mail.domainchanged.com]

mail.domainchanged.com is the primary.  This did not help.  What is the trick?
