+  # parts, these rules disallow certain non-alphanumeric characters, as

+  # Empty components (two dots in a row) are not valid in RFC 2822, but Exim

+  # constructed as "firstinitial.secondinitial.familyname" when applied to
+  # a name without a second initial.) However, a local part starting
+  # with a dot or containing /../ can cause trouble if it is used as part of a
+  # file name (e.g. for a mailing list). This is also true for local parts that
+  # contain slashes. A pipe symbol can also be troublesome if the local part is
+  # incorporated unthinkingly into a shell command line.

+# htpassword will _NOT_ work for exim4.
+
+# For CRAM-MD5 exim needs access to the UNENCRYPTED passwd - the example

+# Hosts that are allowed to use AUTH are defined by the

+# "*", which allows authentication to all hosts over all kinds of
+# connections if there is at least one authenticator defined here.
