What settings are necessary for setting up a .Mac account? At the VERY least for mail but would like calendars as well if its even a possibility.
Mail is simple enough. You just need to set up an account in Evo to use IMAP:
Yoinked from here: http://www.neowin.net/forum/topic/658662-mobileme-imap-settings/
I don't know how to sync calendars though. You might need to proxy it through something else that can sync to it and then connect evo to that (Can google calendar do that?)
