I'm running OX Community Edition (OXCE) on a Smarthost (Ubuntu 6.06.2) which fetches mails from the MX of our ISP.

There are some users configured in OXCE, but should recieve Mails direct from the ISP-Mail-Account. These accounts are not to be fetched by fetchmail and external mails remain on the real MX-Host.

But now, when a mail is written on the local OXCE-Server and should be send to the "external" account it isn't transported, regardless the transport I've configured in /etc/postfix/main.cf and /etc/postfix/transport(.db).

As mentioned before I have still tried diffrent transport-parameters/transport-maps of postfix' main.cf. For the first I only give you the parameters, which didn't lead to success:

virtual_transport = hash:/etc/postfix/transport


mailbox_transport_maps = hash:/etc/postfix/transport

user@example.com smtp:[mail.example.com]

Is there anyone, who has solved this problem or can give me hints about the right postfix parameter/mapping?
