This document explains what you, as a user, will notice when the system
|
|
switches from sendmail to qmail.
|
|
|
|
This is a global document, part of the qmail package, not reflecting the
|
|
decisions made by your system administrator. 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.
