to use a custom imap port you have to change the line
self.connection = cls(host, 1430)
in
C:\Users\YOUR NAME\AppData\Roaming\XBMC\addons\plugin.programm.xbmcmail\resources\lib\client.py

sorry, but i don't have enough knowledge of xbmc and python to make this configurable.

next problem is sorting. i like it best to have the mails sorted by date in reverse order. (lastest == first). the line
finish_kwargs = {
'update_listing': 'is_update' in plugin.request.args,
'sort_methods': ('playlist_order', )
in
C:\Users\YOUR NAME\AppData\Roaming\XBMC\addons\plugin.programm.xbmcmail\addon.py
points to it. it looks like that you have to parse the mail header to enable custom sorting. but that's out of my knowledge too.
