For details on + + * which local delivery agent qmail is configured to use, + * whether qmail is configured to use dot-forward, + * whether ezmlm is installed, + * whether fastforward is installed, and + * all other local configuration features, + +see your local sendmail-qmail upgrade announcement (which your system +administrator may have placed into /var/qmail/doc/ANNOUNCE). + + +--- Mailbox location + +If your system administrator has configured qmail to use binmail for +local deliveries, your mailbox will be in /var/spool/mail/you, just as +it was under sendmail. + +If your system administrator has configured qmail to use qmail-local for +local deliveries, your mailbox will be moved to ~you/Mailbox. There is a +symbolic link from /var/spool/mail/you to ~you/Mailbox, so your mail +reader will find the mailbox at its new location. + + +--- Loop control + +qmail-local automatically adds a Delivered-To field at the top of every +delivered message. It uses Delivered-To to prevent mail forwarding +loops, including cross-host mailing-list loops. + + +--- Outgoing messages + +qmail lets you use environment variables to control the appearance of +your outgoing mail, supplementing the features offered by your MUA. For +example, qmail-inject will set up Mail-Followup-To for you automatically +if you tell it which mailing lists you are subscribed to. See +qmail-inject(8) for a complete list of features. + +If you're at (say) sun.ee.movie.edu, qmail lets you type joe@mac for +joe@mac.ee.movie.edu, and joe@mac+ for joe@mac.movie.edu without the ee. +sendmail has a different interpretation of hostnames without dots. + + +--- Forwarding and mailing lists + +qmail gives you the power to set up your own mailing lists without +pestering your system administrator. + +Under qmail, you are in charge of all addresses of the form +you-anything. The delivery of you-anything is controlled by +~you/.qmail-anything, a file in your home directory. + +For example, if you want to set up a bug-of-the-month-club mailing list, +you can put a list of addresses into ~you/.qmail-botmc. Any mail to +you-botmc will be forwarded to all of those addresses. Mail directly to +you is controlled by ~you/.qmail. You can even set up a catch-all, +~you/.qmail-default, to handle unknown you- addresses. + +See dot-qmail(5) for the complete story. Beware that the syntax of +.qmail is different from the syntax of sendmail's .forward file. + +If your system administrator has configured qmail to use the dot-forward +compatibility tool, you can put forwarding addresses (and programs) into +.forward the same way you did with sendmail. + +If your system administrator has installed ezmlm, you can use ezmlm-make +to instantly set up a professional-quality mailing list, handling +subscriptions and archives automatically. + +If your system administrator has installed fastforward, you can easily +manage a large database of forwarding addresses.
