    Okey...
    I've a serios spam problem on a client server...
    is there a way to configure exim to NOT RELAY
    so... that the FROM: could only contain a domain in the server.

    cause... once autenticated... (ie a normal user) ... mails using any email address could be sent (ie all this new viruses around).
    So, I want to configure this server so that only the local_domains can send mail (the FROM ... yes to any address.

    Also... an optional configuration where autenticated users could only send email using their OWN domain(s) only (main + addons, etc) , could be also good to know.

    Regards

    If it's related to incoming SPAM you can try the following (presuming that you have SA installed):

    1. Integrate RBL
    2. Install Vipul's RAZOR ... SA Will Pick It Up Automatically...
    3. Install DCC ... modify your local.cf accordingly in case you would prefer dccifd
    4. Reject High Score Mails (say 20+) from being delivered in case if they escape the RBL's also...

    Hope this helps.
