Hello,

For a mailserver migration, where to old mailserver is hosted at an ISP
and new mailser is hosted in house, I have to rewrite addres while sending.

What I want to do is this:
- The DNS MX record is changed to the new Postfix mailserver
- If the new mailserver receives an e-mail for user and the
users mail account isn't migrated yet to the new mailserver, the
e-mail will be sent to user
- With the option smtp_generic_maps I rewrite the address from
user to user.

That works fine so far, if the mail is received from a host which is in
$mynetworks. If the host is from outside, the address is no rewritten.

How can I change Postfix' behavior, that e-mails from all hosts will
pass address rewriting?

Ihsan
