+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 \fIall\fR of its MX
+records are contained in the given exclude list.
+
+This option can be repeated to add mail exchangers to the exclude list.
