Be aware that entries found in both the Allow and Deny fields will result in the
user's messages being Denied. The Deny field take precedence over the Allow
field.
The use of Group names in the allow and deny fields is acceptable; however, the
group name must be the actual group name and not that of the groupnames
internet address. Use the actual group name as it appears in the Group view in
the Domino Directory.
Tip: Domino 6 has a notes.ini variable that can be used to limit the number of
recipients that can be included in a single message. If the number of recipients
in an incoming STMP message exceeds the number of recipients you
specified for the variable
rejected.
Use of this variable will limit the effectiveness of directory harvesting and will
also eliminate spam messages which are sent to large numbers of users
within your organization.
4.2.3 Disable routing mail to groups
New in Domino 6 is the ability to stop routing mail to groups. By enabling a
Notes.ini variable,
any mail addressed to a group name. If the variable is not set, the router would
normally allow mail addressed to a group name to be delivered to all the
members of the group. This ini variable will mostly affect messages send to
groups via SMTP, although all mail addressed to groups will be blocked
regardless of the origin of the message.
Mail sent to groups by Notes users will be sent, because Notes client does a
group expansion before sending the message off. By the time the router gets the
message, it looks like it is sent to multiple, individual recipients, not groups.
However, if internal users send mail to a group with a syntax
(groups@localinternetdomain.com or group@notesdomain.com) that isn't
expanded by the client, these messages will be rejected. Any other clients, even
authenticated, can't send mail to groups. This includes iNotes Web Access
users.
, the message will be
, the Router will no longer route
