Unwanted Internet e-mail messages (spam) can be a distracting nuisance to GroupWise
users. Your first line of defense against spam is the Internet Agent. Your second line of defense is
the Junk Mail Handling feature of the GroupWise Windows client.

82.1 Configuring the Internet Agent for Spam
Protection
®
In ConsoleOne , you can configure the Internet Agent to reject messages in certain situations:
Messages are received from known open relay hosts or spam hosts (Internet Agent object >
Access Control > Blacklists).
Messages are received from any hosts that you specifically do not want to receive messages
from (Internet Agent object > Access Control > Default Class of Service > Edit > Allow
Incoming Messages, Prevent Incoming Messages, and Exceptions).
Messages are received through an anti-spam service that uses an "X" header field to identify
potential spam (Internet Agent object > SMTP/MIME > Settings > Junk Mail).
Thirty messages are received within 10 seconds from the same sending host (Internet Agent
object > SMTP/MIME Settings > Security Settings). The number of message and the time
interval can be modified to identify whatever you consider to be a potential mailbomb.
Messages are received from SMTP hosts that are not using the AUTH LOGIN host
authentication method (/forceinboundauth startup switch).
The sender's identify cannot be verified (Internet Agent object > SMTP/MIME Settings >
Security Settings).
For detailed setup instructions on these anti-spam security measures, see
Unwanted E-Mail from the Internet," on page
Messages that are identified as spam by the Internet Agent are not accepted into your GroupWise
system.
