A high-performance command-line driven mailing-list scrubber. Can verify a mailing-list without sending any actual message. Each address is recorded as being verified (as near as possible), failed, or to be retried. Works with text files. Processes up to a million or more addresses per day. Can optionally function also as a direct mailer for aiding fast list processing. This is not a stand-alone mailing-list manager but a tool to aid maintenance of existing LARGE mail or contact lists.
