How to integrate a new (ICAP) AV scanner into amavis?

Hi,

could someone please explaint to me or point me to the documentation of the syntax in the amavis 15-av_scanners?

What I´m trying is to make use of the c-icap-client. So I would like to pass the email via the ICAP Client to an external ICAP Server for scanning.

My ICAP Example

# ['MY AV ICAP Server',

# '/usr/bin/c-icap-client','-s response -i 192.168.17.215 -f {}',

# [0], [2],

# qr/^Infected: (.+)/m,

# ],

It´s not working this way. Although when I execute the c-icap-client manually it works fine:

c-icap-client -s response -i 192.168.1.1 -f sample.pdf

So what I do not understand is:

Line 1: that´s just a name , OK.

Line 2: includes the path to the binary and parameters I want to pass, but what is {} ??? Is this where the file will be passed to the external application?

Line 3: What is [0], [2] doing? Should I change it? to what?

Line 4: And what should I put into the line with "infected" Is this the parsing for the output of the icap result?

I would also like to write my own script or binary, that will get emails from amavis to be scanned.

But I do not know, how the syntax in 15-av_scanners should be, so that my script or binary will be executed in the right way.

Best regards,

Benjamin
