Actually, CRAM-MD5 *IS* supported by Courier-IMAP.

See this link:

http://www.inter7.com/courierimap/INSTALL.html#crammd5

But I think you're on the right track: I DO NOT think that
Courier-IMAP's vpopmail authentication module supports
CRAM-MD5, effectively making CRAM-MD5 authentication with
vpopmail impossible.

This means that my ONLY choice is to prevent tmda-ofmipd
from even announcing it's CRAM-MD5 capability, since email
clients like Pegasus Mail will attempt to use CRAM-MD5
if it is announced, and you can't prevent it with a config
field or file.

So, I simply removed the 'cram-md5' string in the capability
announcement line.

Is there a better way to disable this? Perhaps a config flag?

Thanks!
