[exim] :blackhole:

Hello list!

I've been testing an exim-courier-mysql setup that was created by
someone else.
What is the point of the router below, if all the viruses are being
rejected during
acl_smtp_mime and acl_smtp_data anyway?
Also anything ditched with a router to ":blackhole:" would not get any
proper notification.
Would they?

# ditch_malware:
#   driver = redirect
#   allow_fail
#   data = :blackhole:
#   condition = ${if and { {match {$h_X-ACL-Warn:}{.*malware.*}} \
#                          {eq {${lookup mysql{select users.on_avscan 
from users,domains \
#                         where localpart = '${quote_mysql:$local_part}' \
#                         and domain = '${quote_mysql:$domain}' \
#                         and users.on_avscan = '1' \
#                         and users.domain_id=domains.domain_id}}}{1} }} 
{yes}{no} }
