[KLUG Members] sendmail blocking spam with dnsbl?

[bill]

How can I tell if sendmail is blocking spam like I expected?

I applied the block as it appears here:

http://spamcop.net/fom-serve/cache/294.html

Specifically, I applied the first one, dnsbl, because the second one, enhdnsbl,
wouldn't compile.

But am still receiving spam.  How can I tell if it is working or not?  Is there
a log file somewhere that indicates when spam is being blocked?

kind regards,
