There have been a few interesting changes to the NMapi recently. Here
is a quick summary from what comes to my mind; Build instructions are
below.

Changes (short version):

There is an imap gateway, we can accept connections from Outlook in
the proxy, we have taken a few steps to make it much easier to support
other programming languages like Java and Python in the future and
buiding NMapi is quite simple now.

Changes (longer version):

• Andreas has checked his imap gateway server into svn about two weeks ago. This is great news, of course. My latest changes to NMapi break
  the build, however, so there will be another announcement once this is
  fixed.
• NMapi will now build with an unpatched Mono build and without any
  additional libraries. You will still need the latest preview (Mono 2.2
  RC1), which you can download from here:
  http://mono.ximian.com/monobuild/preview/download-preview/ . Java is
  not required anymore.
• There is a new ONC/RPC .x generator "mlog", written in C#, which
  makes multiple backends (like generating code for other languages)
  possible and also removes the compile-time dependency on Java.
  Currently it will generate an xml representation of the data which is
  later translated to C# using XSLT.
• Most NMapi data structures have been redefined in xml and C# code is
  generated through XSLT.
• The NMapi API is generated from xml as well; We should be able to
  generate other languages in the future.
• SRestrictions, SPropValues and Notifications are now represented in
  a proper class hierarchy.
• There is a new (proxy) server:
  • It supports multiple protocols. (Currently the teamXchange ONC protocol.)
  • Now accepts connections from Outlook (using the TeamXChange
    provider on Windows).
  • Events work now.
  • There is a new web interface built right into the proxy.
• The MAPI AddressBook interface and a (custom) administration
  interface has been added.
• Unnecessary features of the OncRPC library have been removed, some
  new one have been added and the port from Java (which was basically
  quick&amtp;dirty) has been cleaned up.
• The RPC protocol has been improved and a few "teamXchange-isms" have been removed.
• Some updates from jumapi (VIPcom) have been merged.
• Improvements and fixes all over the place.

Building (Linux or Mac):

1. Get Mono 2.2 RC1 from here:
   http://mono.ximian.com/monobuild/preview/download-preview/ Make sure
   you have all the required packages installed (like mono-tools).
2. Make sure xsltproc is installed.
3. Check out NMapi using "svn co
   http://svn.openmapi.org/svn/openmapi/trunk/nmapi/"
4. Run "make". Done.

We will provide a binary release and packages later this month.
