[RCU] Why does RC2 use user@localhost for authenticating against IMAP?

Entry page logins use the format: user/pasword when authenticating against IMAP. This portion works for my server. However, for some reason when viewing the folders section under personal settings, RC2 tries to switch to user@host/password which does NOT work on my server.

Where can I fix this?

Also, RC2 does not display the buttons/search bar properly when using Firefox version 2.0.0.11. Anyone else have this problem?

Thanks,

Tommy

(BTW, upgrading from beta-1 to rc2 is a complete waste of time. You might as well just reinstall RC and upgrade only the database part.)
