    Hi,

    Does anyone know if it's possible for exim to reject emails if the destination is in the "localdomains" (not "secondarymx") list and the destination user doesn't exist as an alias or POP3 account?

    We're getting a lot of rejection emails for other mailservers, where a spammer has used random characters to a create an email address at our clients domains. We've got SPF records set up in all DNS zone files, but few 3rd Party mail servers currently support it. We got over 1000 emails from different mailer-daemons yesterday which sit in our queue, and it's using up resources after MailScanner, spamd and ClamAV have scanned each one.

    Just hoping that CPanel get their act together and sort out proper clustering soon so that we can have dedicated incoming mail servers :rolleyes:

    Thanks,


    Rob

    Go on, have a guess
    You need to make sure that you set the Default Address to :fail: (not :blackhole:) and then emails t non-existing accounts/aliases should b rejected. You can then go one step further and install a dictionary attack ACL:
