Scott,

Maybe HopHigh should exclude the IANA Reserved Blocks.  See below.

I believe that it does exclude the Private use IPs (RFC1918).

http://www.iana.org/assignments/ipv4-address-space shows that the 1.x.x.x 
Class A range is reserved by IANA today.  That means that tomorrow it could 
be assigned to Korea or China or any other country.  Anyone using an IP 
address in the 1.x.x.x range, even as an internal IP, is running the risk 
of all sorts of problems.  If we hard-code Declude JunkMail to ignore those 
IPs, and they *do* end up in the hands of spammers, you'll end up with more 
spam.

RE: [Declude.JunkMail] Word Filters - Spammers getting smarter

2002-07-08 Thread Madscientist

Caution...
I had a similar test in Message Sniffer some weeks ago with tragic
results - too many false positives so we had to pull it. We have a mod
in the works to get around this hack - including a stream filter to drop
all html comments before matching. 

That would be a good one for you to look at Scott if it fits in your
system.

It turns out that simply counting the number of comments doesn't work
reliably. Neither does the comment to content ratio. There are some
specific comments that can be filtered - but that's not widely effective
except on repeats of the same spam run - although that does reduce the
load so we tend to include those when we see the opportunity.

For example, a few of the spam runs done by this technique had nursery
rhymes built in (I can't quote here)... a few others looked like chunks
of personal messages... The producer apparently can point the engine at
a text file and have it cycle through that text to pull segments for
randomly placed comments in a round-robbin fashion.

Hope this helps,
_M

RE: [Declude.JunkMail] Lotus Looks to Deep-Six Spam With Domino Upgrade

2002-07-08 Thread Tom

If you are interested:

From: Computerworld
By JENNIFER DISABATINO
JULY 01, 2002

IBM's Lotus Software Group unit last week said that the next version of its
Notes/ Domino e-mail and collaboration software will include server-side
tools designed to stop spam messages before they hit end-user mailboxes.
Ed Brill, an IBM software operations manager, said Domino 6 will include a
set of antispam tools, plus the ability to automatically block e-mail from
suspect IP addresses, such as those placed on the Realtime Blackhole List
maintained by Mail Abuse Prevention System LLC (MAPS) in Redwood City,
Calif.

MAPS, a not-for-profit group run primarily by volunteers, vets complaints
about unsolicited bulk commercial e-mail. Companies and Internet service
providers can subscribe to MAPS's list and set blocks so their servers won't
accept e-mail messages coming from the specified IP addresses.

Users can set filters in the R5 version of Lotus Notes client software so
that an e-mail that includes the phrase make money fast, for example, will
be routed to a folder designated for spam. Brill said Domino 6 will be able
to block messages at corporate e-mail gateways, reducing the amount of spam
traffic that reaches networks, servers and PCs.

The Domino upgrade, which is due out in September along with Notes 6, will
also include scripts that e-mail administrators can use to set
message-filtering rules.

But there's a possible trade-off. Brill acknowledged that having the filters
on the server side might make it take longer for legitimate e-mail messages
to pass through routers and get to in-boxes. But he didn't specify how much
of a performance hit users might experience.

A spokesman for Microsoft Corp., Lotus' main rival in the messaging software
market, said Microsoft mostly relies on third-party vendors that offer
filtering products for Exchange users.

And even Lotus will continue to lean on partners for some of the more
sophisticated spam-filtering technology after Domino 6 ships, Brill said.

Matt Cain, an analyst at Meta Group Inc. in Stamford, Conn., said any
improvement in antispam capabilities is a good thing for users. But the
antispam technology being added to Domino is not state-of-the-art, he
said.

Compared with some of the specialized, third-party antispam software now
available, Cain added, what Lotus plans is in the same league, but it won't
win on feature function. For example, other tools can identify spam
signatures and allow users to stop a blast of e-mail messages sent from an
IP address that hasn't already been blocked, he said.



Just Go Away
Domino 6 will include the following antispam capabilities:

System rules that let IT administrators filter all incoming mail messages
based on their content


Preconfigured filtering scripts to which other suspect words and phrases can
be added


The ability to block messages from IP addresses that belong to known
spammers


Improved support for using Domino's directory to stop spam from being routed
throughout a company
