elspy 0.1.1
-----------
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.

CHANGES
-------
* Fix serious bug in header_add() and log_write() wrappers:
they failed to escape '%' characters in the passed-in string, which
could cause Exim to dump core since it treats those strings as
format strings.
* Change to accept messages by default if there's any Python
problem, not just an import problem. Made this behaviour a bit more
customizable with some #define's at the top of elspy.c
