Mailing list management is one of qmail's strengths. Notable features:* qmail lets each user handle his own mailing lists. The deliveryinstructions for user-whatever go into ~user/.qmail-whatever.* qmail makes it really easy to set up mailing list owners. If the usertouches ~user/.qmail-whatever-owner, all bounces will come back to him.* qmail supports VERPs, which permit completely reliable automatedbounce handling for mailing lists of any size.* SPEED---qmail blasts through mailing lists an order of magnitudefaster than sendmail. For example, one message was successfullydelivered to 150 hosts around the world in just 70 seconds, with qmail'sout-of-the-box configuration.* qmail automatically prevents mailing list loops, even across hosts.* qmail allows inconceivably gigantic mailing lists. No random limits.* qmail handles aliasing and forwarding with the same simple mechanism.For example, Postmaster is controlled by ~alias/.qmail-postmaster. Thismeans that cross-host loop detection also applies to aliases.* qmail supports the ezmlm mailing list manager, which easily andautomatically handles bounces, subscription requests, and archives.
