Getting black list servers (a.k.a. 'RBL Servers' in SIMS terminology,
a.k.a. DNSbl servers) to cause messages to be rejected is a two-step
process. In addition to entering the RBL server's domain name to SIMS' RBL
Servers list, you also need to add their possible responses to SIMS'
internal blacklist. At minimum, most of the RBLs use 127.0.0.2 as a basic
response. Some of them use other responses in the 127.0.0.2-127.0.0.255
range, depending on the sub-list in which a particular address might be
listed. Note that the range does _not_ include 127.0.0.1.
Spamtraps are fine for eliminating spam that fits their relatively narrow
criterion, but they're not going to stop a whole lot even when they're
working properly. To get maximum effect from them, it's not enough to
simply set them up in SIMS. You also need to publish them in places where
spammers are going to harvest them, like on a publicly accessible web page.
Another good tactic is turn de-activated addresses into spamtraps. For
example, I've got a few addresses that used to belong to people who no
longer work for my employer. When I noticed, in going through my SIMS logs,
that those addresses seemed to be getting spam aimed at them, I simply made
spamtrap entries for them in my router. I now see several rejections a day
in my logs due to those spamtraps. Not a lot, but enough to let me know
that the spamtraps are doing their job.

That would be a bit rash. Many of the people on this list are using SIMS'
anti-spam features to good effect. Your problems are likely simple
configuration issues. Also, realize that you are never going to block 100%
of the spam aimed at your server. Every time we figure out a way to block
some spammer tactic, they'll find a new way in, like rats finding their way
into a barn. Unfortunately, since fighting spam is largely a reactive
undertaking, we're always going to be one step behind them. ('Same planet,
new scum')

One more general bit of advice is to make sure you're running the latest
beta version of SIMS so that you have the most up-to-date set of anti-spam
gizmos. You can get it by FTP at
<ftp://ftp.stalker.com/pub/SIMS-PPC-18b9d14.sit.hqx>
or
<ftp://ftp.stalker.com/pub/SIMS-68k-18b9d14.sit.hqx>
Don't worry about it being 'beta' software -- it's been around for quite a
while and has been proven to be quite stable.
