Integration of Kaspersky Security 8.0 for Linux Mail Server with Postfix as part of Zarafa

Prior to integrating Kaspersky Security 8.0 for Linux Mail Server with MTA Postfix as part of Zarafa, it is necessary to stop and disable autorun of Clamav, Spamassasin and Amavis services. To disable Amavis:

1. Comment the following strings in /etc/postfix/master.cf:
   
   #amavis unix - - - - 2 smtp
   #       -o smtp_data_done_timeout=1200
   #       -o smtp_send_xforward_command=yes
   #       -o disable_dns_lookups=yes
   #       -o max_use=20

   #127.0.0.1:10025 inet n - - - - smtpd
   #       -o content_filter=
   #       -o local_recipient_maps=
   #       -o relay_recipient_maps=
   #       -o smtpd_restriction_classes=
   #       -o smtpd_delay_reject=no
   #       -o smtpd_client_restrictions=permit_mynetworks,reject
   #       -o smtpd_helo_restrictions=
   #       -o smtpd_sender_restrictions=
   #       -o smtpd_recipient_restrictions=permit_mynetworks,reject
   #       -o smtpd_data_restrictions=reject_unauth_pipelining
   #       -o smtpd_end_of_data_restrictions=
   #       -o mynetworks=127.0.0.0/8
   #       -o smtpd_error_sleep_time=0
   #       -o smtpd_soft_error_limit=1001
   #       -o smtpd_hard_error_limit=1000
   #       -o smtpd_client_connection_count_limit=0
   #       -o smtpd_client_connection_rate_limit=0
   #       -o receive_override_options=no_header_body_checks,no_unknown_recipient_checks

2. Comment the following string in /etc/postfix/main.cf:
   
   #content_filter = amavis:[127.0.0.1]:10024

3. Restart Postfix using the following command:
   
   # /etc/init.d/postfix reload

Now Kaspersky Security can be installed as specified in the documentation.
