Subject: [Exim] Exiscan Patch - multiple spamd servers and/or virus scanners
Hi.

Attached is a patch against exiscan versions 4.30-14 or 4.30-15 to add
the following two new features.

Patch against 4.30-14 - http://www.sircd.org/qnet.exiscan-4.30-14.patch
Patch against 4.30-15 - http://www.sircd.org/qnet.exiscan-4.30-15.patch

- ----

*) Fail over spamd servers.

This adds the option to specify multiple 'spamd' servers. If a
connection fails to the 1st server, exim will then try the next one in
the list. It will repeat this process until it can open a tcp connection
to a server or comes to the end of the list.

Example:

hide spamd_address = 192.168.0.1 783 : 127.0.0.1 783 : ...

- ----

*) Multiple virus (malware) scanners.

For the really paranoid you can have the option to have multiple AV
programs scan your mail. Just add the extra configuration options to
your existing av_scanner line.

Example:

av_scanner = \
        clamd:/var/run/clamav/clamd.sock:\
        cmdline:/opt/kav/bin/aveclient -p /var/run/aveserver -s
%s/*.eml:INFECTED:^LINFECTED (.+)


- -----

I have run both features on my own setup without any problems but I
would appreciate any comments from anyone who could test on other systems.

Regards.

Vince.
