 A :class:`CharField` that checks that the value is a valid email address.
 
+.. admonition:: Incompliance to RFCs
+
+    The default value of ``max_length`` is not compliant with RFCs 3696 and 
+    5321. It is suggested that new projects override the ``max_length`` to 254 
+    characters, as this would be capable of storing all email addresses as 
+    defined by RFCs 3696 and 5321. 
+    
+    The default value is not being changed at this time to maintain backward 
+    compatibility with previous versions of Django.
