[vox] spam question



Hey all,

As I'm sure is the case with many of you who run your
own Internet-connected servers w/ Linux, I get a lot
of spam relay attempts. I have configured my postfix
to avoid the open relay problem and I have yet to see
anything in the logs which suggests that any of these
attempts have succeeded.  

I get an average of 3-4 failed spam attempts each day.
The overwhelming majority come from China or Korea,
though I do sometimes see other types of failed
attacks (mod_proxy, etc) from Europe and other parts
of the world.

Sometimes I do a WHOIS on the originating IP address,
and among other information it returns an email
address along the lines of "report spam to
abuse@<hostname>.com."

My question: How often (or do you?) take the time to
report spam relay, mod_proxy, or crack attempts to the
address provided? And if you do complain, what exactly
do you send them? A snippet of your log entry? Would
there be any additional security concerns raised by
providing the offending ISP with your own hostname or
IP address?

Or do you believe that the ISP's admin is himself
responsible in many of these cases and that
complaining would therefore be futile?

Your thoughts, please.

Thanks, Matt
