+Release 7.5.16 fixes two limitations in email support.  First, the
+mail-sending interface has been reworked to generate the formatted
+message to a temporary file rather than a buffer.  This allows sending
+very large attachments.  Second, IMAIL's handling of file-based folders
+has been reworked to store a copy of the file in an "external string"
+The in-heap data structures no longer contain excerpts from the file,
+but instead keep indexes into the file and extract the excerpts on
+demand.  This allows reading very large mail files with reasonably-sized
+heaps (however it does require enough virtual memory to hold an image of
+the file).  The actual in-heap storage is quite small, approximately 100
+bytes per message.
