[Resending this msg since mod seems not to have released my original msg
yet]
Hi guys.
I can't figure out what's going wrong with my below config snippet to
make my Debian version of Exim 4.80 use Avira AntiVirus 3.1 as a generic
command line virus scanner:
> warn message = This message contains malware ($malware_name)
> set acl_m0 = cmdline:/usr/lib/AntiVir/guard/avscan -s
> --batch --scan-mode=all %s; /bin/echo -e \N"\navira_retval
> $?"\N:\N^avira_retval 1$\N:\N.*ALERT: ([^;]*) ;.*\N
> malware = *
> log_message = This message contains malware
> (avira:$malware_name)
When I manually invoke the command line scanner I get the following output:
> # /usr/lib/AntiVir/guard/avscan -s --batch --scan-mode=all eicar.com.txt

The below is the list of codes Avira possibly returns, when I launched
the above test with the EICAR dummy virus I indeed got a result code of 1:

I'm fiddling with this since almost 2 hours now and can't figure out
what's going wrong... :-(
I'm already using a couple of command line scanners as follows which are
all working fine (which I can tell from Exim's mainlog, they all trigger
on the EICAR dummy virus):
> warn message = This message contains malware ($malware_name)
> set acl_m0 = cmdline:\
> /usr/bin/avgscan --arc %s; echo -e
> \N"\navg_retval $?"\N:\
> avg_retval 5:\
> \NVirus identified *(.*)$\N
> malware = *
> log_message = This message contains malware
> (avg:$malware_name)
> warn message = This message contains malware ($malware_name)
> set acl_m0 = cmdline:\
> /usr/local/bin/fpscan --report %s; echo -e
> \N"\nfprot_retval $?"\N:\
> fprot_retval 1:\
> <([^>]*)>
> malware = *
> log_message = This message contains malware
> (f-prot:$malware_name)
> warn message = This message contains malware ($malware_name)
> set acl_m0 = cmdline:\
> /usr/bin/antivir --allfiles -z -rs %s:\
> ALERT:\
> [[](.+)\[]]
> malware = *
> log_message = This message contains malware
> (antivir:$malware_name)
I'm sure I'm missing s/t obvious, but it's been ages since I was really
"fluent speaking Exim", so your help would be much appreciated.
Thank you!
