// We see the following in the e1.eml
// Notice that Chilkat replaced the full path with just the filename.
// The full local path is not part of the email that gets sent..

// ...
// --------------020807050607070004010609
// Content-Type: image/jpeg; name="starfish.jpg"
// Content-Transfer-Encoding: base64
// Content-Disposition: attachment; filename="starfish.jpg"
// 
// ...
// --------------020807050607070004010609
// Content-Type: application/pdf; name="fishing.pdf"
// Content-Transfer-Encoding: base64
// Content-Disposition: attachment; filename="fishing.pdf"
// ...

// Before sending, each filename can be changed within the email object.
// For example:
llSuccess = loEmail.SetAttachmentFilename(0,"orange_starfish.jpg")
llSuccess = loEmail.SetAttachmentFilename(1,"tuna_fishing.pdf")

// Look at the new MIME source of the email in a  text editor...

// ...
// --------------020807050607070004010609
