+#################################
+
+# This router handles aliasing using a traditional /etc/aliases file.
+#
+##### NB  You must ensure that /etc/aliases exists. It used to be the case
+##### NB  that every Unix had that file, because it was the Sendmail default.
+##### NB  These days, there are systems that don't have it. Your aliases
+##### NB  file should at least contain an alias for "postmaster".
+#
+# This router handles the local part in a case-insensitive way which
+# satisfies the RFCs requirement that postmaster be reachable regardless
+# of case. If you decide to handle /etc/aliases in a caseful way, you
+# need to make arrangements for a caseless postmaster.
+#
+# Delivery to arbitrary directories, files, and piping to programs in
+# /etc/aliases is disabled per default.
+# If that is a problem for you, see
+#   /usr/share/doc/exim4-base/README.Debian.gz
+# for explanation and some workarounds.
