Abstract
An electronic mail (email) server has a database that stores unique identifiers (UID's) of electronic messages. A proxy obtains mappings from the database for previously existing UID's of electronic messages that have been determined from a polling operation. A cache caches the mappings of UID's and the proxy is operative for purging the cache of the previously existing UID's after polling.
