KAPERSKY ANTI-VIRUS - FOR FREEBSD-OPENBSD-BSDI MAIL SERVER User Manual page 74

This book does not describe the sendmail, Qmail, Postfix and Exim
mail systems and their performance concept. If you have any ques-
tions related to these programs, refer to the corresponding documen-
tation.
Right after you install the program on a server (see chapter 2) you must
integrate it with one of the mail systems listed above and define its settings
(see subchapter 7.6).
The Keeper program interacts with the daemon process and performs the
following functions on a server:
•
The program parses the entire incoming and outgoing SMTP
traffic and transfers it to the daemon process that subsequently
checks it for viruses and disinfects it.
•
If a virus is detected in a message body or its attachments, the
daemon process returns the corresponding code to Keeper that,
depending on the returned value, may perform the following op-
erations:
•
•
•
For the message recipient:
° notify the recipient about the infected message de-
tected (see subchapter 7.6.2.4.1);
° block the message from being delivered to the re-
cipient mailbox (see subchapter 7.6.2.4.2);
° pass the infected (see subchapter 7.6.2.4.4) or dis-
infected (see subchapter 7.6.2.4.3) message to the
recipient mailbox.
For the administrator — notify the administrator about
the infected message detected and delivers the mes-
sage to the administrator mailbox (see subchap-
ter 7.6.2.6).
For the message sender — notify the sender about the
infected message delivered from his(her) mailbox
(see subchapter 7.6.2.7).
