+# The name of a mail exchanger, the forwards of whose domains we should
+# ignore. For example, if one mail exchanger, mx1.example.com, has
+# strict spam filtering, it may be acceptable to have remote forwarding
+# for domains that have mx1.example.com as their sole mail exchanger (MX
+# record). In that case, you might want to exclude those domains from
+# the report, by naming mx1.example.com here.
+#
+# A forward will be excluded from the report only if *all* of its MX
+# records are contained in the given exclude list.

+# Default: [] (empty)
