<div dir="ltr">I use those 3 in order. I have not had an issue with spamcop blocking something that it shouldn't. Barracuda grabs the majority (due to it being the first one) of spammers so I do not have to worry about whitelisting. I have this theory (and I do not recommend anyone else following it), IF you end up on Barracuda's list, you probably deserved it. I haven't seen many false positives from Barraucda or ZEN.<br>

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>

<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.<u></u><u></u></pre>
<pre><u></u> <u></u></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.<u></u><u></u></pre>
<pre><u></u> <u></u></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.<u></u><u></u></pre>
<pre><u></u> <u></u></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 :) )<u></u><u></u></pre>
