    Virtual Users And Domains With Postfix, Courier And MySQL (Debian Etch)

    I've configured my mail server using the HOWTO Virtual Users And Domains With Postfix, Courier And MySQL (Debian Etch) and am having issues with the transport table.

    For one of my domains (let's say, I have in the transport table: smtp:[] where is the IP address of the other mail server I want all mail to go to. Attemption to email [email protected] gets a bounce:

    550 5.1.1 <[email protected]>: Recipient address rejected: User unknown in virtual mailbox table (in reply to RCPT TO command)

    I setup in the domains and transport tables.

    I'd like to keep my Postfix server as the MX for but if I can't get this working, I may have to just point the MX record directly to the other mail server.

    Did you restart Postfix?

    No, I don't think so. I'll try that and see if it changes anything.

    I have the same issue. I definitely restarted Postfix. But domain A will not forward messages to the mail server deginated in Transport table. I've setup domain A in the Domains table, then I setup domain A to transfer All emails to the designated mail server in the Transport table. Like so...

    I've also tried...



    * smtp:[IP Address]

    I restarted postfix after each change.

    I receive the error message below in the mail logs.

    "550 5.1.1 <[email protected]>: Recipient address rejected: User unknown in virtual mailbox table (in reply to RCPT TO command)"

    The mail server is funtional, i.e. emails can be received and sent.

    Any Ideas?
