# If you are running exim4-daemon-heavy or a custom version of Exim that
# was compiled with the content-scanning extension, you can cause incoming
# messages to be automatically scanned for viruses. You have to modify the
# configuration in two places to set this up. The first of them is here,
# where you define the interface to your scanner. This example is typical
# for ClamAV; see the manual for details of what to set for other virus
# scanners. The second modification is in the acl_check_data access
# control list.

# For spam scanning, there is a similar option that defines the interface to
# SpamAssassin. You do not need to set this if you are using the default, which

# modify the acl_check_data access control list to enable spam scanning.

# of a named domain. The RFCs require this facility, but it is disabled
# in the default config since it is rarely used and frequently abused.
# Domain literal support also needs a special router, which is automatically
# enabled if you use the enable macro MAIN_ALLOW_DOMAIN_LITERALS.
