how to get new messages first on listMessages?

listMessages methods always return sorted by date asc

What sequence are you giving it?
According to the RFC the sequence is defined as:

seq-range       = seq-number ":" seq-number
                    ; two seq-number values and all values between
                    ; these two regardless of order.
                    ; Example: 2:4 and 4:2 are equivalent and indicate
                    ; values 2, 3, and 4.
                    ; Example: a unique identifier sequence range of
                    ; 3291:* includes the UID of the last message in
                    ; the mailbox, even if that value is less than 3291.

I haven't been able to find anything about how the server should order messages, so I guess the server can do it as it wants (Although I haven't found a server with doesn't order messages by ascending sequence number)
