In the above examples, topics is a space-separated list of topic names. The user may further customize the specific content they will receive using the following formats:

• Specify topics without a Web. prefix
• Topics must exist in this web.
• Topics may be specified using * wildcards
• Each topic may optionally be preceded by a '+' or '-' sign. The '+' sign means "subscribe to this topic" (the same as not putting anything). The '-' sign means "unsubscribe" or "don't send notifications regarding this topic". This allows users to elect to filter out certain topics (and their children, to an arbitrary depth). Topic filters ('-') take precedence over topic includes ('+').

• Each topic may optionally be immediately followed by an exclamation mark ! or a question mark ? with no intervening spaces, indicating that the topic (and children if there is a tree depth specifier as well) should be mailed out as complete topics instead of change summaries. ! causes the topic to be mailed every time even if there have been no changes, ? will mail the topic only if there have been changes to it. This only makes sense for subscriptions.

Note that when using the "news mode" ! or ? specifiers are used the entire topic text is mailed out as HTML. The newsletter template is used to generate the content in this mail, using whatever skin is selected in the topic being mailed.

In addition, the %STARTPUBLISH% and %STOPPUBLISH% markers used by TWiki:Plugins.PublishContrib to delimit the text to be published are respected.

Installation Instructions

• If you have TWiki 4.1 or later, and Perl 5.8, you can install from the configure interface (Go to Plugins->Find More Extensions)
  • The webserver user has to have permission to write to all areas of your installation for this to work.
• If you have a permanent connection to the internet (and Perl 5.8), you are recommended to use the automatic installer script
  • Just download the MailerContrib_installer perl script and run it.
• Notes:
  • The installer script will:
    • Automatically resolve dependencies,
    • Copy files into the right places in your local install (even if you have renamed data directories),
    • check in new versions of any installed files that have existing RCS histories files in your existing install (such as topics).
    • If the $TWIKI_PACKAGES environment variable is set to point to a directory, the installer will try to get archives from there. Otherwise it will try to download from twiki.org or cpan.org, as appropriate.
    • (Developers only: the script will look for twikiplugins/MailerContrib/MailerContrib.tgz before downloading from TWiki.org)
  • If you don't have a permanent connection, you can still use the automatic installer, by downloading all required TWiki archives to a local directory.
    • Point the environment variable $TWIKI_PACKAGES to this directory, and the installer script will look there first for required TWiki packages.
      • $TWIKI_PACKAGES is actually a path; you can list several directories separated by :
    • If you are behind a firewall that blocks access to CPAN, you can build a local CPAN mini-mirror, as described at http://twiki.org/cgi-bin/view/Codev/BuildingDakar#CPAN_local_minimirror
• If you don't want to use the installer script, or have problems on your platform (e.g. you don't have Perl 5.8), then you can still install manually:
  1. Download and unpack one of the .zip or .tgz archives to a temporary directory.
  2. Manually copy the contents across to the relevant places in your TWiki installation.

1. 1. Run configure and enable the module, if it is a plugin.
   2. Repeat from step 1 for any missing dependencies.

• To make sure the installation was successful, run the mailnotify script from the command line, with no parameters. In this case it will print out what it would have done to STDOUT.
