elspy 0.1
---------

elspy is a layer of glue code that enables you to write Python code to
scan email messages at SMTP-time with the Exim MTA (mail transport
agent).  elspy also includes a small Python library with common
mail-scanning tools, including an interface to SpamAssassin and a
simple-but-effective virus detector.

Exim is a highly flexible and customizable MTA (mail transport agent)
for Unix Internet email servers.  One of the new features in Exim 4.0
was the local_scan() API, which allows sites to supply custom code for
scanning messages at SMTP time, accepting or rejecting them based on
message content.  Normally, you have to write the local_scan() function
in C.

Python is a high-level, extensible, embeddable, object-oriented
programming language.  Scanning email is a great example of something
that you can do in any decent programming language, but do a lot more
easily in Python than in C.

The core of elspy is a C local_scan() function that embeds a Python
interpreter in Exim, allowing you to write your own local_scan()
function in Python instead of C.


REQUIREMENTS
------------

elspy requires Exim 4.0 or greater, and Python 2.0 or greater.
