Hi Erik:
Does this all have to be on a single line, or can I split it into
multiple lines for readability?
i.e.:
-a whitelist.foo.com
-a whitelist2.jabroni.com
-r bl.spamcop.net
-r fakebl.carlosmencia.com

Hi Edwin,
Each RBL has a domain suffix that goes with it. You get that from the
config details for who owns the rbl. Spamcop is 'bl.spamcop.net' and
the details are at this site:
http://www.spamcop.net/fom-serve/cache/291.html
You then decide whether this is an implicit whitelist or a blacklists.
Prefix the domain suffix with -r to blacklist and -a to whitelist. You
must put all whitelists first. That will give you a line that roughly
looks like this:
-a whitelist.foo.com -a whitelist2.jabroni.com -r bl.spamcop.net -r
fakebl.carlosmencia.com
Which you put into a file called /var/qmail/control/blacklists. As far
as which ones I'd recommend, I just use the default '-r
sbl.spamhaus.org' in my blacklists file. Many of the others block dial
up and dynamic ip users, which is normally ok, except many of my users
use SMTP-AUTH for outgoing to my server. SMTP-AUTH comes after the
blacklists, so this causes issues for my users.
I got joe-jobbed before, and have since kept strict spf records that
only allow my SMTP-AUTH enabled servers send e-mail for my domains.
Hope this helps.
Thanks,
Erik
