A method for identifying discrepancies in an email distribution list is provided in various embodiments of this present invention. The method includes receiving from an originating client an email addressed to a list of recipients; examining the list of recipients to identify one or more possible amendments to the list of recipients; and informing the originating client of any identified amendments. In other embodiments, examining the list of recipients further includes comparing the recipient list with one or more trusted lists or a directory to identify one or more possible amendments to the list of recipients to identify those recipients missing or sharing a common attribute. In other embodiments it is determined if other names in the directory, but no in the recipient list, also share the common attribute. Subsequently, one or more amendments may be made to the recipient list based on such absent names.
