F-Secure Internet Gatekeeper for Linux/Administrator’s Guide

Allows the spam to pass. "X-Spam-Status:" is added to the header of e-mail that is classified
as spam. You can use the sorting function on the client to classify e-mail in which the value
of "X-Spam-Status:" starts with "Yes" as spam. The spam detection is recorded in the log
and the administrator is notified.
Change subject
Change subject
(spam_action=change_subject, spam_change_subject_prefix)
Modifies the Subject of an e-mail that is classified as spam. If you specify a character string,
it is prefixed to the Subject. The maximum number of characters is 99.
We recommend that you specify the text string in English.
Although you can use other languages as well, the text is encoded as UTF-8. Accordingly, if
the subject of the incoming e-mail is encoded by using, for example, ISO-2022-JP, the text
may not be shown correctly in Outlook or other e-mail clients.
Notify the administrator by e-mail
Notify Admin
(spam_notify_admin)
Sends a notification to the administrator by e-mail. Specify the e-mail address, mail server,
and detection message in
Settings to notify the administrator
under “Common settings”.
To separate notifications from standard e-mails, "X-Admin-Notification-Id: [number]" is
added to the header. This also prevents the notification from being detected as a virus.
“Number” is a random number, which is set as admin_notification_id in the settings file
during the installation.
Quarantine
Quarantine(keep)
(spam_quarantine)
Quarantines spam. The spam is quarantined in the directory that you set in
Quarantine
directory
under “Common settings”.
Specify this setting only if sufficient disk space is available.
Even if you enable this setting, it is not possible to delete the e-mail completely or block it
from being delivered to the user. The reason for this are the specifications of the POP
protocol.
Defining parent server by user
User Selective Parent
(self_proxy)
Allows the client to select the POP server.
The user can specify the POP server by specifying their mailer user name in the format <user
name>@<POP server name> (or <user name>#<POP server name>).
POP user restriction
PAM-based Account verification
(proxyauth_pam_account)
Restricts which users can connect.
Authentication is performed using PAMs (Pluggable Authentication Modules). You can change
the authentication method in the /etc/pam.d/fsigk_pop file.
For more information, see "
Proxy authentication using Internet Gatekeeper
", 102.
Add or remove users
User DB
Edits the database of users who are permitted to connect. You can add, delete, and modify
users. The POP service uses the user database only to check user names. Because
password authentication is performed by the POP server, the password in the user
database is not used.
