Forwardings won't work

[jpieper]

Hi guys, I used this article to setup my postfix mailserver on my centos5.3 server. It works fine but my forwardings won't work.

users:
to@domain.tld

forwardings:
source: from@domain.tld
destination: to@domain.tld

I also tried to add "from@domain.tld" to "users" table but then it will be delivered directly to from@domain.tld instead of forwarding to "to@domain.tld"... Adding "domain.tld" to "transport" table I am getting "loops back to myself".

At the moment I am getting a "Undelivered Mail Returned to Sender" mail after sending am mail to "from@domain.tld".

My "mysql-virtual_forwardings.cf" is set to "virtual_alias_maps" in my main.cf.

So, what am I doing wrong?
