Yes. Step 1: Create your own blacklist. Step 2: Report the IP. Optional
step 3: Create rules in SA to query your blacklist created in step 1. Of
course, I am merely assuming here you are actually asking something
relevant to SA...
Joking apart, your question is *really* vague. In cases like this, it is
a lot better to describe your actual problem, rather than asking
something this broad. You still can add the missing info, and tell us
about your problem.
Bunch-o-pointers regarding "blacklisting" an IP address:
SA does not reject, quarantine, drop or deliver mail. All it does is
scoring. Thus, in case your "blacklisting" query involves these, you'd
better check back with your SA calling layer.
If you definitely are about rejecting mail from a given IP, you'd want
to look at your MX STMP configuration.
If you are happy to "severely punish" mail sent from a given IP, without
a need to reject the mail, SA can do what you want. Punishment ranges
from scoring, classifying as spam, all the way up to quarantining and
simply dropping down the bin bucket -- the latter two depending on the
following tools in your mail-processing chain.
Flooring mail in SA sent via a given IP (aka blacklisting) is possible
in various ways, depending on your needs, configuration, accuracy of
your configuration (like receiving mail via mailing lists) -- and of
course your knowledge of mail headers, SA rules, SA pseudo headers, and
RE in general. But I digress...
Likely candidates are the X-Spam-Relays-* Untrusted and External pseudo
headers. But that could be done more efficiently in your SMTP, if you
mean *black* as a pseudonym of *block*.
And if you really dislike the IP, you could als craft some simple
Received header rules in SA. Though at this point, we're crossing the
line between blacklist and blacklist. And deep header parsing.
Where did I start off again? Oh, right -- what exactly is the problem
you're facing and the result you want to achieve?
