Debian courier package
======================

The "courier-mta" suite in Debian is compiled with these notable specifics
and differences to the upstream source:

* A system user `courier` owns the files and runs the daemons, it gets
  created automatically by a maintainer script (postinst)
* Socks 5 support is not compiled in due to the lack of courier-sox, for
  more details please check https://bugs.debian.org/755092#10
* Better adhere to the File Hierarchy Standard: configuration files are to
  be found in /etc/courier, pid and lock files in /run/courier, etc.
* Some binaries were renamed because their original names are too generic,
  e.g. showconfig is courier-mtaconfig in Debian.

Maildir setup
-------------

All the mail servers integrated into the Courier suite are using
the maildir storage format instead of the mbox format (refer to
the maildir(5) manual page for more information).

The default maildir for a given user is ~/Maildir, although you
can change it by editing /etc/default/courier or running
dpkg-reconfigure -plow courier-base.

To create a maildir, just run as the email user:

  # maildirmake Maildir

Vpopmail
--------

There is no support for vpopmail in the Debian packages, because
this would cause Courier to be removed from the main distribution.
See Debian bugs #182040 and #248319 for more information.

Postfix
-------

See http://www.postfix.org/faq.html#maildir for information about
how to advise Postfix to deliver into maildir's.

Virtual Users
-------------

For virtual users specified in userdb, SQL or LDAP the following
values are required: home,uid,gid and password. Please if you
plan to use sqwebmail package, then must read information about
the SUID and SGID in the sqwebmail README.Debian file.
