# mail2s9y.php, 0.6
# -----------------
#
# Seperate PHP-Script to allow email blogging.
# REQUIRES: PHP CLI-binary, Linux/Cygwin(?), local Mail installation.
#
# Contributed by Sebastian Nohn <seb...@no...>, Gijs van Tulder <gvt...@gm...>
# Implemented by the Garvin Hicking <me...@su...> of the s9y group (www.s9y.org)
#
# Changes:
# --------
#
# 0.6 (2004-04-13): Update with patches from amonthera (related to lowercasing attributes)
# 0.5 (2004-02-20): An security update by Alex Copeland, who pointed out that images could be uploaded without authentication.
# 0.4 (2004-01-19): Another update from Bjoern Schotte, who added interactivity to s9y. It will now mail back to ask for a category for the item.
# 0.3 (2004-01-13):
#                   Automatic URL replacement (translates http://... and other common protocols into hyperlinks). Thanks to Bjoern Schotte for the patch!
#                   Made Login modes working for s9y 0.5-CVS again
# 0.2 (2003-12-02): Beautified code
# 0.1 (2003-12-01): 3 different authentication methods are now available (security issues)
#                   Resets any cookie/session variables to block webrequests to this page
#
# To get this to work, do the following:
# --------------------------------------
#
# 1. Possibly adjust the first line of this script to point to your PHP CLI-binary. Put the package
#    PEAR-Package Mail_Mime (http://pear.php.net/get/Mail_Mime) into your s9y/bundled-libs folder, so
#    that you have an existing s9y/bundled-libs/Mail/mimeDecode.php file.
#
# 2. Make your local MTA recognize an E-Mail adress to be responsible for s9y. In most setups,
#    just add the following line to your "/etc/aliases" file:
#
#    s9y: "|/path/to/mail2s9y.php [username] [password]"
#
#    The name 's9y' refers to the email account you chose to use for your local mail server.
#    Of course, change the path to something valid.
#
#    If you use the 'cmdline' authentication method (configuration see below) you have to provide
#    the [username] and [password] credentials to your s9y-installation. If
#    password-security is important to you, use a .procmail forwarding rule and set appropriate
#    file permissions to your .procmail file (0600). However, the preferred authentication method
#    is 'mailbody' and should be used to disallow anybody to mail a blog entry to your special
#    email account, if ever exposed to the public.
#
#    If you don't know how to setup an account or adjust the line above to a .procmail rule,
#    you most probably don't want to use this script at all.
#
# 3. Adjust the variable $params['s9ypath'] below to point to your s9y installation.
#
# 4. MAKE SURE, that your mail-account user is in the same group as the owner of the file
#    'serendipity_config_local.inc.php'! Otherwise, your configuration can't be read.
#    Usually, the file belongs to the webserver, so if you don't want to stick the user into
#    the same group, you have to change the ownership of the file to your target user. Bear
#    in mind, that the original permission ('ug+rwx') are updated any time you make changes to
#    your s9y-setup.
#
# 5. Write an E-Mail to your chose local address. The subject will be the title for your entry,
#    the body your text and possible attachments will be uploaded to your s9y directory structure.
#
#
# Also make sure that...
# ----------------------
#
# * Preferably your E-Mail blog-message should contain no unwanted
#   linebreaks after the usual 70 char limit. If your E-Mail client does
#   that to you, try to configure it not to; otherwise this may result
#   in an ugly HTML display in your blog, and/or broken HTML tags you could
#   have posted
#
# * If you use automatic URL rewriting (which transforms http://, ftp://,
#   ...) links into valid HTML, please take care that this url is without
#   any special characters (brackets, punctuation characters, ...), or else
#   you may get those characters included in the auto-guessed URL.
#
# * Feedback is appreciated! If anything doesn't work, please post your
#   problems to either the s9y-support forums/mailinglists or mail the
#   author personally.
