[Kolab-devel] some python code for cyrusimap: annotation and sieve

Hello I use Kolab as a base for a new service I want to propose.
I'm writing the application in python 2.4 using turbogears framework.

python imaplib support already very well ACL with cyrus, but
I had to extend the python imaplib library to include annotations to
manage the "expire" option
I also extended a sieve library I found on the web to manage STARTTLS
http://www.crazy-compilers.com/py-lib/managesieve.html

If someone want to add some extension, I recommend the intensive use of tcpdump
to compare a working tools like cyradm or sieveshell with your code (as I did)

Here is my code, first imaplib and last managesieve

Hope this help
