    You can send emails using the Exchange Web Services API (EWS). EWS is a set of old fashioned ASMX web services hosted on the same server as OWA. Microsoft has even published an open source managed API wrapper on GitHub for EWS.

    Here is an example on how to send emails using EWS:
    http://code.msdn.microsoft.com/Send-Email-with-Exchange-50189e57

    The GitHub readme also includes links to samples.

    Usually EWS can be found at http://yourexchangeserver/ews/exchange.asmx but with the managed API you can use autodiscovery to automatically find the address of EWS on your Exchange server.

    Update regarding Exchange 2003:

    You can access the Exchange 2003 mail store via HTTP using WebDAV. WebDAV is a bit of a pain to use because you may have to use Forms Based Authentication (FBA) if that is what your OWA installation requires (in comparison EWS can use Windows Authentication even if OWA on Exchange 2007/2010 is using FBA).

    I have never tried sending mails using WebDAV for Exchange (although I have used WebDAV for a number of other things) but I found an example on MSDN that you may want to try. It uses Windows Authentication so it will not work if your Exchange 2003 OWA is set up to use FBA. If you need to use FBA let me know – I may have some sample code somewhere that you can use.
