As you may know, if NetSuite sends an email regarding a case, it has a return address that will direct replies back into the case's message list.  This feature is essential to manage cases by email.

I have written a package of enhancements to NetSuite's case management functions to allow NetSuite to respond to cases within 30 minutes instead of 90 minutes, and to offer custom notifications about those responses.   The problem I'm having is that if I send email from inside a suitescript, the return address is supplied by the NS email sending method, which requires a simple "from" string.  The result is that the customer, assignee, or escalatee get emails which cannot be replied to, since the reply will go to the sender instead of being stored in the case.  This renders suitescript for
