I use two Hotmail-accounts in Mail.
Since i upgraded to Panther one of the two is shown normally (as i was used to) as a folder directly viewable in Mail, with some subfolders in it.
The other account is shown only as a folder in Inbox, with its junk and other folders, directly into it.
Besides, there are other strange things happening: see thread Mail: Could not find host: (null).
Can someone explain?
