Does any vendor make an anti-spam product that is cheap, runs on a Windows
server, and can be configured only to filter messages that are best
classified as gibberish? There is a whole class of spam that mostly slips
through anti virus filters that consists of nothing but meaningless streams
of characters and nonsensical expressions using misspelled words.

Additional requirements:

- I would want to filter out such gibberish to a special mail account and
then forward the good e-mail to a regular mail server.

- I need to be able to whitelist both individual email addresses and entire
domains, because we do get many e-mails filled with lots of technical part
numbers and jargon, but thankfully this is from less than 100 domains that
we can easily whitelist.

- I need to be able to turn off other kinds of spam filtering. (I find too
many false positives with most spam filters.)

Are there any good options for such a product?

How about two out of three? http://www.roaringpenguin.com/

Our product doesn't run on Windows, but we make available an ISO image
that turns any blank PC into a filtering server in about 15 minutes.

It can handle all your other requirements.

David.

Suggestion: try posting to a windows group.

Which newsgroup knows more about how to process e-mail than this one?

Exim running on Cygwin with SpamAssassin (EximConfig).

Just configure SpamAssassin disabling all the rules except the ones for
gibberish.

Second choice: sendmail + MailScanner + SpamAssassin + Cyrus IMAP under
M$ Services For Unix (you need a Windows Server version). Haven't used
it, I'm not even sure that all that software have been ported there.

No problem, SpamAssassin will give you a header with a score, if the
score is higher or equal than the value set by the rules you used then
redirect the mail (procmail is one possibility here, I'm not sure if SA
can do it by itself, I use it in a different configuration (non
Windows)).

Not sure but SA probably can handle this; if not, then exim can handle
it. Again I use it in a different configuration and white & black
lists are handled somewhere else.

Yeah, hard work... all the packages I mentioned are free you just have
to install and configure them.

Next question: And how are the users going to read their mail?

You have a couple of choices, UW-IMAP and Dovecot (also Courier but
that one is harder to build). You'll probably need Dovecot which
allows virtual users and exim can be configured to use those.

Probably none of the configurations I described are well tested.

The title is comp.mail.sendmail, lackwit.

sendmail is a program.

If you want to ask about virus scanners and MS, use one of the MS
groups.

Your good with generalities. What's the specific newsgroup that has
discussions about e-mail servers and processing that you would recommend?
If you can't name one then maybe that's because there isn't one.

The fact is that people in this group have lots of experience processing
mail with a wide variety of technologies. Just as people post procmail
questions and questions about other mailers, it's not that far-fetched to
ask related questions about servers that process e-mails.

I'd recommend you stop posting off-topic here... while you can still post.

If you can't find a facility, do you just crap in the middle of a mall
because it's convenient for you?

Did you know that abuse@giganews.com has an AUP regarding off-topic
posts/USENET abuse which you're violating?
