            Bug ID: 2112
           Summary: Avast scanner does not work when options specified
           Product: Exim
           Version: 4.89
          Hardware: x86
                OS: All
            Status: NEW
          Severity: bug
          Priority: medium
         Component: Content Scanning
          Assignee: tom@???
          Reporter: andrew@???

When options are specified to the avast scanner it fails to scan and issues a
defer instead for all mail.

For example.

av_scanner = avast:/var/run/avast/scan.sock:SENSITIVITY +pup

It seems to me the logic is built for the following protocol response.

== start ==

220 DAEMON
SENSITIVITY +pup
210 SENSITIVITY DATA
200 SENSITIVITY OK

== end ==

How ever the actual protocol echos back the settings like so:

== start ==

socat /var/run/avast/scan.sock -
220 DAEMON
SENSITIVITY +pup
210 SENSITIVITY DATA
SENSITIVITY +worm +trojan +adware +spyware +dropper +kit +joke +dangerous
+dialer +rootkit +exploit +pup +suspicious +pube
200 SENSITIVITY OK

== end ==

The current code does not handle the line starting with SENSITIVITY it expects
a line starting with 200 instead.
