PDFX enhancement: new Email.Type options 5 and 6 re-implement the original Type options 1 and 2 (i.e. launch the standard email client for sending interactively or non-interactively, respectively). The new implementation uses the latest Windows 7/8 MAPI API routines under direct A-Shell control rather than the MAPI interface built in to the PDFX driver (which didn't work reliably or at all with newer Windows systems).
There are still too many variables (different email clients, logon security frameworks, versions of Windows, etc.) to be sure that this will work in your environment, but it has a much better chance of working than the old Types 1 and 2.
