Hello,
I see you have two things out. 1st you using RBLS, that could give you a lot
positive false spam. 2nd you completely have commented out best thing in
SPAMDYKE. Is sniffing IPs in reverse DNS. Most of bots and spams comming from
Internet zombies. Here are my advices:
1 - comment out dns-blacklist-entry=zen.spamhaus.org
2 - uncoment reject-empty-rdns, reject-ip-in-cc-rdns, reject-missing-sender-mx
and reject-unresolvable-rdns
3- into /etc/spamdyke/blacklist_recipients add your domain in format
@your-domain (it will block all mails like to: n...@your-domain from:
n...@your-domain)
4- into /etc/spamdyke/ip-in-rdns-keyword-blacklist-file put these words :
dsl
.com
.net
broadband
dynamic
I could guarantee you will fall bellow 1% of SPAM with nearly zero false
positives. Of course someone who can't follow certain guidelines for theirs
servers will not be able to send you e-mails at all. But you can easily handle
it by adding IP's in /etc/spamdyke/whitelist_ip or adding senders into
/etc/spamdyke/whitelist_senders
I stop using any RBLS services ages ago, they are way unreliable.
Good luck,
Eduard Švarc
