Automatic installation: ----------------------- Now there is a port of AntiVir MailGate for FreeBSD. You can download this port from our ftp server ftp.antivir.de/freebsd/ports. After downloading the port, change to the / directory and extract the tarball. Change to /usr/ports/security/avmailgate and do make and make install. If sendmail is running on port 25, kill sendmail before installing AntiVir MailGate. Manual installation: -------------------- The installation on FreeBSD is almost the same procedure as on Linux. Just some little notes. The pid files per default reside in /var/run. This directory usually is owned by root:wheel and the permissions are drwxr-x---. This inhibits AntiVir MailGate from creating the pid files there. You may either use another directory for the pid files or you can change the Group in avmailgate.conf to "wheel" and make /var/run group writable. This should not inherit any security risks.

Here is the description how to install AntiVir MailGate to work with postfix: First you have installed AntiVir MailGate described in INSTALL. There are two possible ways of integrating AntiVir MailGate under postfix. One of these is to make AntiVir MailGate listen at port 25 and forward the emails to postfix. The other is to integrate AntiVir MailGate in postfix as content filter. This is possible from the Snapshot 20000520 version of postfix onwards. A release with content filtering capacity is available from version 20010228 onwards. We prefer to use the content filter method because the whole SMTP functionality of Postfix will be available. 1. Content filter ----------------- Edit the /etc/services and add the following entries: # Content Filter for postfix antivir 10024/tcp #Port for avgated smtp-backdoor 10025/tcp #Port for postfix backdoor Edit /etc/avmailgate.conf and modify the following entries: # Select interface and port, the smtp daemon will listen on. # Port may be given as a number or a service name. ListenAddress localhost port antivir # Select how mail should be forwarded. # Send mail by piping it thru sendmail (this is the default) #ForwardTo /usr/sbin/sendmail -oem -oi # Or if you want the mail to be sent by SMTP ForwardTo SMTP: localhost port smtp-backdoor If you are using SuSE Mail Server 2 change also the following line from: #AllowSourceRouting NO to: AllowSourceRouting YES Close AntiVir MailGate and restart it: /etc/init.d/avgate restart Insert the following entry in /etc/postfix/master.cf: # service type private unpriv chroot wakeup maxproc command + args # (yes) (yes) (yes) (never) (50) smtp inet n - n - - smtpd # F<FC>r AntiVir Maild<E4>mon localhost:smtp-backdoor inet n - n - - smtpd -o content_filter= Make sure that the first character in the table is not a space. The entry smtpd -o content_filter deactivates the relevant line in a second invocation of postfix. (to avoid generating a mail loop!) Insert the following entry in /etc/postfix/main.cf: # Antivir Einbindung content_filter = smtp:127.0.0.1:10024 Restart postfix: /etc/init.d/postfix restart Note: If postfix sets all emails to status "deferred" after installing AntiVir MailGate search the line: defer_transports = local and add the following comment char using #: #defer_transports = local 2. Listening on port 25 ----------------------- This is the second way how to implement AntiVir MailGate in postfix: Edit the file master.cf. Locate the following line: smtp inet n - n - - smtpd and add the following comment char using #: #smtp inet n - n - - smtpd This will prevent postfix from listening at the SMTP port, and enable avgated to do so instead. Emails forwarded by avgatefwd will then be processed by sendmail wrapper /usr/lib/sendmail, which is included with postfix. Restart postfix: /etc/rc.d/postfix restart
