+# RFC 2822 - style email validation for Python

+# for support of mx and user check
+# This code is made available to you under the GNU LGPL v3.
+#
+# This module provides a single method, valid_email_address(),
+# which returns True or False to indicate whether a given address
+# is valid according to the 'addr-spec' part of the specification
+# given in RFC 2822.  Ideally, we would like to find this
+# in some other library, already thoroughly tested and well-
+# maintained.  The standard Python library email.utils
+# contains a parse_addr() function, but it is not sufficient
+# to detect many malformed addresses.
+#
+# This implementation aims to be faithful to the RFC, with the
+# exception of a circular definition (see comments below), and
+# with the omission of the pattern components marked as "obsolete".

+# from the "tokens" defined by the RFC.  Each of these tokens is
+# tested in the accompanying unit test file.

+# The section of RFC 2822 from which each pattern component is
