They can still be a soft target.  Most of the DNSBLs were unprepared 
to deal with denial of service attacks.  Some of them have closed 
down after an attack.  That can be a problem for users as most people 
have a "configure and forget" setup or it's a default vendor setup.

The bandwidth may be enough for current usage.  The more mirrors you 
have, the better.  If your DNSBL is effective, you might be able to 
get help with that.  The "problems" with your setup is not worse than 
other resources that are commonly used by users from this mailing list.

Someone pointed out that it's not a good idea to do more DNS lookups 
as it affects the performance of SpamAssassin.  It does not matter 
whether your DNSBL is included in the default configuration as people 
will use it if they believe that it is effective in stopping 
spam.  If you are concerned about marketing, then it may matter to you. :-)

If that is wanted, I could talk to ISPs for hosting such DNS here in 
Austria. After all, we are all getting advantages from this, and as long 
as it's a free service, I can offer free mirrors.

I guess that if HOSTKARMA were included in the default build then I will 
need more mirrors to handle the load.
