-.SH "NAME"
-qmail-upgrade \- user-visible differences between qmail and sendmail
-.SH "INTRODUCTION"
-You will notice some differences
-when the system switches from
-.B sendmail
-to
-.BR qmail .
-.TP 5
-1.
-.B qmail-local
-sends incoming mail to
-.B ~\fIyou\fB/Mailbox
-by default,
-not
-.BR /usr/spool/mail/\fIyou\fB .
-Your system administrator has changed your
-.B MAIL
-environment variable so that your mail reader looks for
-.BR ~\fIyou\fB/Mailbox .
-.B \fR(\fB/usr/spool/mail
-is a massive security problem.)
-.TP 5
-2.
-.B qmail-local
-pays no attention to
-.BR .forward .
-It has a much better mechanism,
-.BR .qmail ,
-so that you can handle not only forwarding
-but even your own mailing lists.
-See below for more details.
-.TP 5
-3.
-.B qmail-local
-pays no attention to
-.BR /etc/aliases .
-Your system administrator
-can use the
-.B .qmail
-mechanism instead.
-See below.
-.TP 5
-4.
-.B qmail
-does not support the
-.B \e\fIyou\fB
-mechanism
-for ignoring aliases.
-The
-.B .qmail
-mechanism is much more flexible;
-see below.
-.TP 5
-5.
-.B qmail-inject
-has a completely different philosophy from
-.B sendmail
-on interpreting non-fully-qualified host names.
-It uses fixed rules, not DNS.
-Some examples at UIC:
-
-.EX
- russet -> russet.math.uic.edu
-.br
- newton -> newton.math.uic.edu
-.br
- ut.ee -> ut.ee (a host in Estonia)
-.br
- ut.ee+ -> ut.ee.uic.edu
-.br
- uicvm+ -> uicvm.uic.edu
-.EE
-
-Here the
-.I default domain name
-(for hosts without dots)
-is
-.B math.uic.edu\fP,
-and the
-.I plus domain name
-is
-.B uic.edu\fP.
-.TP 5
-6.
-Unlike
-.BR sendmail ,
-.B qmail-inject
-doesn't replace host names with canonical names.
-Example:
-.B qmail-inject
-won't change
-.B postmaster@ftp.cs.berkeley.edu
-in your header to
-.BR postmaster@kohler.cs.berkeley.edu .
-.TP 5
-7.
-.B qmail-local
-adds a new field,
-.BR Delivered-To ,
-before every delivery.
-It uses the contents of
-.B Delivered-To
-to prevent mail forwarding loops.
-.TP 5
-8.
-If you send a message with only
-.B Bcc
-recipients,
-.B qmail-inject
-will add
-.B Cc: recipient list not shown:;\fR,
-rather than
-.BR sendmail 's
-privacy-invading
-.B Apparently-To
-header field.
-.SH "QMAIL MAILING LISTS"
-.B sendmail
-deals with aliases, forwarding, and mailing lists
-at the very heart of the mail system.
-
-.B qmail
-takes a radically different approach.
-It gives you the power to set up your own mailing lists without
-pestering your system administrator.
-
-Under
-.BR qmail ,
-you are in charge of all addresses of the form
-.B \fIyou\fBBREAK\fIanything\fR.
-The delivery of
-.B \fIyou\fBBREAK\fIanything
-is controlled by
-.B ~\fIyou\fB/.qmail-\fIanything\fR,
-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
-.BR ~\fIyou\fB/.qmail-botmc .
-Any mail to
-.B \fIyou\fBBREAKbotmc
-will be forwarded to all of those addresses.
-Mail directly to
-.B \fIyou\fB
-is controlled by
-.BR ~\fIyou\fB/.qmail .
-You can even set up a catch-all,
-.BR ~\fIyou\fB/.qmail-default ,
-to handle unknown
-.B \fIyou\fBBREAK
-addresses.
-
-Your
-.B .qmail
-files, like your old
-.BR .forward ,
-may list files,
-forwarding addresses,
-or other programs to run.
-(But beware that the syntax is a bit different;
-see
-.B dot-qmail(5)
-for more details.)
-.B qmail-local
-automatically
-detects forwarding loops the instant they occur,
-even if they happen indirectly through other hosts.
-
-As a helpful special case, if a
-.B .qmail
-file is empty, it refers to
-.BR ~\fIyou\fB/Mailbox .
-For example, if you touch
-.BR ~\fIyou\fB/.qmail-direct ,
-mail for
-.B \fIyou\fBBREAKdirect
-will act like
-.B \e\fIyou\fB
-did under
-.BR sendmail .
-
-Addresses that don't contain a username are handled by the
-.B alias
-user.
-For example, your system administrator has set up
-.B ~alias/.qmail-postmaster
-to handle mail for
-.BR Postmaster .
-(Note to administrators:
-.B ~alias
-doesn't apply to addresses that start with a user name,
-with certain exceptions.)
