Lotus Domino 6 spam Survival Guide for IBM eServer

XM SpamStop

XM SpamStop from XM Technologies Inc. integrates with Domino 6 and provides

inbound messaging content security with over 300 built-in algorithms, including

blacklists, malformed header checks, whitelists, auto whitelists, and message

signatures. A smart application, SpamStop continually updates itself to counter

the ever-changing, but simple methods of spammers to get their junk mail to you.

Based on customer project experiences with SpamStop, XM Technologies has

organized their offering to address what they have identified as key challenges in

anti-spam implementations, as follows:

±

DNS Blacklists are not 100% effective.

DNS Blacklists do not cover hotmail, yahoo, and other big ISPs, since it is

impossible to do global blocking against them. As well, many small

companies can inadvertently end up on a DNS Blacklist and have problems

removing themselves.

±

Users have differing requirements.

SpamStop allows a company to have per-user or per-department settings to

accommodate different languages, non-western characters, special

department circumstances, and so forth.

±

Stopping messages before they get to the user is often most effective.

SpamStop allows for a simple workflow where no one is forced to read

unwanted or inappropriate e-mail content; it can be stopped at the server

before ever going to a user

’

s bulk mail or spam folder.

±

Management is unwilling to spend the necessary funds.

Spam is a low profile problem in many companies

—

unless a senior manager

is receiving it. Licensing of SpamStop is based on a flat per-server fee plus

monthly maintenance, making it easy to make a business case to

management.

SpamStop incorporates the following key features:

±

Uses an adjustable scoring system of 1 to 100

±

Allows for user-specific or global settings

±

Does between 10 and 300 built-in checks

±

Checks DNS Blacklist (2-20 servers)

±

Uses and automatically creates Whitelists

±

Checks Blacklists

±

Checks allowed language formats

±

Workflow system deals with spam management or allows it to flow to the user

±

Checks message signatures (known spam)
