Hello - The c-client mailing list has been renamed to the imap-uw mailing list.
The fundamental problem is that your server does not implement the IMAP SORT extension. You would not have this problem with a server that offers SORT.
Next, what options are you giving to mail_sort()? If you are setting SE_UID, then the code does not (can not) do any prefetching. This is because c-client's cache is completely implemented by message sequence number, not by UID. In general, options such as SE_UID and FT_UID should be avoided, especially when doing multiple message operations.
Instead, get the sequence numbers, and then afterwards translate them to UIDs (if that is what you want) via mail_uid(). This may sound backwards to someone who is thinking in terms of UIDs, but trust me, c-client cache will be happier and will reward you for your cooperation.
You may find the use of sequence numbers to be beneficial in other ways as well; use UIDs just for synchronization and do everything else with sequence numbers. c-client will reward you for that as well.
