    Hi all!
    guys, I have a little problem, I'm missing something...
    I'm trying to install a MX Backup server in one of our ISPConfig3 server.

    I read here the way to do it is:

    Being DOMAIN.NET the domain to backup :p MAIL.SERVER.NET the mail server :p and BACKUP.SERVER.NET the backup server :p

    - Adding a MX record in the DNS Zone of the domain in MAIL.SERVER.NET to BACKUP.SERVER.NET with a higther priority.

    Something like: dig mx DOMAIN.NET


    - Create in the back up server an "Advance Mail Routing - Mail Transport" pointing to the first mail server.

    looking like:
    Domain: DOMAIN.NET
    Type: smtp
    No MX lookup: off
    Destination: MAIL.SERVER.NET
    Sort by: 1
    Active: on

    Ok, I done all of this and where I send an email, in the backup server mail log I'm getting:

    NOQUEUE: reject: RCPT from[]: 550 5.1.1 <[email protected]>: Recipient address rejected: User unknown in relay recipient table.....

    That tell me the dns part it is ok but y have some bad config in the ispconfig backup server...

    Can you help me? THANKS
