Sophos.install improvements

[Mark Nienberg]

Julian,

Can you add the following to Sophos.install for v5 installations?

# prevent notifications from causing a mail loop
/opt/sophos-av/bin/savconfig -u set EmailNotifier disabled

# prevent autoupdates (let MailScanner do it instead)
/opt/sophos-av/bin/savdctl stop sav-protect
/opt/sophos-av/bin/savdctl disableOnBoot sav-protect


The email that sophos sends with the on-demand scan results is in turn scanned, 
generating another email which is scanned, etc.

If sav-protect daemon is running, it updates Sophos, but without the locking that 
MailScanner's update uses.


Thanks,
Mark Nienberg
