= Blueprint for the Messaging Module =

Current design is here:
 * http://wiki.sahana.lk/doku.php?id=dev:msg_archi
User Guide:
 * http://wiki.sahana.lk/doku.php?id=doc:message:english

What we need is:
 * Contacts List
 * Admin UI for:
  * Email Settings
  * SMS Settings
 * CAP alerts: http://talksahana.com/2009/03/04/firefox-browser-cap-alerting-plugin-sahana-idea-for-gsoc2009/
 * SMS alerts
 * SMS login / data entry / reports
 * [wiki:BluePrintMessagingModuleJ2ME J2ME client]

=== Email ===
tools.py has mail settings:
{{{
mail=MailS3()
# These settings should be made configurable as part of the Messaging Module
mail.settings.server='mail:25'
mail.sender='sahana@sahanapy.org'
}}}
& a function:
{{{
mail.send(to, subject='None', message='None')
}}}

Can use this to send emails with dynamic data inserted into templates (like HTML pages):
 * http://groups.google.com/group/web2py/browse_thread/thread/f6c903f9c67cfe2e

smtplib is required for sending HTML mails (MIME encoded):
 * http://groups.google.com/group/web2py/browse_thread/thread/3d8ed693dd2f29bc
 * Simple app for sending mails from a form (using smtplib): http://mdp.cti.depaul.edu/appliances/default/show/10

There is a Cron job to check the contents of the !OutBox & send pending messages. On Success it moves the message to the 'Sent' table:
 * http://web2py.com/examples/default/cron
=== SMS ===
The SMS Daemon to handle Inbound messages is a separate Python script.

It can distinguish between simple messages (added to the !InBox of the Messaging Module) & those which are encoded in Binary XML (the output of XForms from the J2ME client).

Q: Do we use Cron to check !OutBox & signal the daemon to send Pending messages? (as for email)

Toolkits we can base on:
 * RapidSMS (Python-based): http://rapidsms.org
 * !PySerial: http://pyserial.wiki.sourceforge.net/pySerial
 * Gammu: http://www.gammu.org (Python-gammu: http://www.gammu.org/wiki/index.php?title=Gammu:Python-gammu)
 * Gnokii: http://www.gnokii.org (!PyGnokii: http://mobilehacking.org/index.php/PyGnokii)
 * Kannel: http://kannel.org (!PyKannel: http://mobilehacking.org/index.php/PyKannel)
 * SMSTools: http://smstools3.kekekasvi.com
