How to forward an Inbound email with attachments which doesn't have case-id or work object.

An inbound email is received with attachments through the email listener. This won't have anything related to work object and as an exception these emails have to be just forwarded with all the attachments to another email-id for reviewing purpose.

Tried with SendSimpleEmail, SendEmailNotification,  SendEmailNotificationWithAttachments, SendEmailWithAttachments (These two call SendEmailNotifcation only) but not attachments. Only email is sent with the body.

Loads of suggestion to assign pyAttachmentPage of Data-EmailMessage to a page of Data-WorkAttach-File or to a page of Data-EmailAttachments but nothing works.

Any suggestion please.
