What exactly are you looking for?
To access the MWC simply open your phones web-browser and type:
www.yourscalixservername.com/m
This will open a rather web 0.1-kinda webpage showing the most recent emails on your account.
If you'd like to connect to the IMAP-interface just set-up a new email account on your phone. This is pretty much self-explanatory as the input mask asks all the relevant parameters.
Just for information:
Either way you won't be able to sync all of your scalix account's data with your phone. It's limited to emails and only those. For the time being you will have to use your PC Suite software and sync locally. Don't even think about NotifyLink.
