Thanks for the feedback, I added the line in general.cfg and restarted the scalix services..still getting the "The username or password is incorrect. Note that passwords are case sensitive. Try again."
Heres how my changes reflect in the general.cfg file..

# The CDA service (used for "type down" in some clients) is more
# efficient if it can check the directory change log before attempting
# to update the access tables that it uses. One slow machines, it may
# also be worth uncommenting the CDA_CHECKTIME tweak to reduce the check
# interval from five minutes to an hour.

# These tweaks limit the number and rate of IMAP connections to the
# server. The IMAP_CONNECTION_LIMIT simply restricts the total number of
# connections to the server -- note that many IMAP clients have several
# connections for each IMAP session. The IMAP_CONNRATE_LIMIT restricts
# the rate at which clients can connect to the server, in this case, at
# most ten connections per second; if clients try to connect faster
# than that, the IMAP server simply slows down the rate at which it will
# accept new connections.

# The IMAP_IDLE_TIMEOUT tweak is the maximum time an IMAP connection
# will wait for a command before terminating the connection. The default
# setting, and the minimum required setting, is thirty minutes. Some
# clients will "refresh" their connection once every thirty minutes
# exactly -- but if they are a little bit late, the server drops their
# connection. Setting a timeout of 31 minutes avoids this problem.
IMAP_IDLE_TIMEOUT=31
# This tweak arranges for Local Delivery to automatically create a
# message store for users who have been created without one.
# Users who have been added using the bulk-add mechanism used by the
# wizard will not have a message store and so setting this tweak allows
# them to receive mail before they have been signed on initially.

thanks again, I appreciate your help
