    I have had to remove the RBL from the advanced exim editor due to the fact it is denying clients outbound mail (503 valid RCPT command) errors.

    I have started Cpanels ACL (Deny hosts listed at spamhaus, spamcop) and was not sure if these rejects are listed in any logs? (does not appear to be in the exim_rejectlog) or if it is even working (Mailscanner is installed).

    It would not be an issue except that many users are on dynamic IP's and these entire subnets get blacklisted and frankly I could care less if my authenticated users are on one of these subnets. (they are not sending spam themselves).

    The complaints about the"503 valid RCPT command" is a real PITA...
