    I'd not use spamcop in an MTA. Too unreliable for an outright reject
    as it's based on their users' opinions of what is SPAM and what is
    not. Unsurprisingly a lot of IPs are blacklisted in SpamCop just
    because someone signed up for the service, subscribed to something,
    and then instead of addressing that problem reported it to SpamCop,<br>
    <br>
    Zen and Sorbs will kill a lot, add greylisting and rejecting mail
    for unknown users and it's as good as Gmail for spamlessness.<br>
    <br>
    We tried it and had a lot of customer complaints so now we just use
    it for a moderate + score in MS.<br>
    <br>
    Cheers<br>

                    <pre>This part I do not agree with. Unless you think all RBL's contains more or less the same IP's, its pretty obvious that your protection improves with more RBL's.<o:p></o:p></pre>
                    <pre><o:p>&nbsp;</o:p></pre>
                    <pre>Also unless you have resource contention in regards to multiple threads, the slowness RBL's introduce doesn't matter, and the system is just waiting for a response from the network, which almost doesn't consume any system resources.<o:p></o:p></pre>
                    <pre><o:p>&nbsp;</o:p></pre>
                    <pre>Personally I have RBL's in both the MTA and in mailscanner. In the MTA I greylist based on a few very trustworthy RBL's and in mailscanner I score based on ohh I don't know 10-20 RBL's. It allows you to have a much more fine-tuned system instead of blocking based on a single RBL at the SMTP level.<o:p></o:p></pre>
                    <pre><o:p>&nbsp;</o:p></pre>
                    <pre>The advantage of having them in mailscanner is mainly that you can whitelist senders, the disadvantage is that senders aren't told that they are listed (but since all the RBL's I use are public db's used in thousands of systesm I trust somebody else will let them know soon enough :) )<o:p></o:p></pre>
