Question regarding AUTH=LOGIN

[Brian Kirsch]

Hello,
I am working on Chandler a Python based Personal Information Management System (www.osafoundation.org).
We are using Twisted as our IMAP library. I am running in to an issue with AUTH=LOGIN. It works for most
IMAP servers as Twisted assumes a base64 encoded challenge. But on some servers such as Cyrus I am getting a non-base64 challenge. I did some searching on the web but I can't seem to find a spec on the AUTH=LOGIN exchange.
Can someone clue me in or point me to some references. There error is included below as well.


Thanks,
