Request for improvement of the PureMessage End User Web Interface

We use PureMessage for UNIX and our users would like the ability to use wild cards in the Approved and Blocked senders lists via email globs.  For example, a user does not want any email from **@**.eu

MATCH TYPES:

exact:
email globs: ? - single char, not "."
             * - sequence chars, not "."
             ** - sequence chars, including "."
             @ never matched
