====== How can i disable Postgrey for a domain or mailadress? ======
You can set a domain or a mail recipients on the whitelist.

Postgrey has its own whitelist under **/etc/postgrey/**
  * whitelist_clients -> here can set complete domains
  * whitelist_recipients -> here can you set email-addresses

Take a look at the files, there are some examples in it.
After your changes restart Postgrey:
<cli>
# /etc/init.d/postgrey restart
</cli>
