    SMTP part of a new mail account dialog doesn't update UI properly
    
    Using "Server requires authentication" checkbox doesn't update
    the new mail account dialog properly, thus it seems like a username
    is required when the server does not require authentication. It's due
    to the dialog being updated properly only on CamelSettings changes,
    while this checkbox doesn't have any direct connection to any
    CamelSettings property.
