you can forward the document with
@Command( [MailForwardAsAttachment] )
than the Document will be forwarded to the address which is in the 'SendTo' field of the selected document. So if the sendTo field not exist, you have to created the field like this
FIELD SendTo:= "person@mail.com" ;
@Command( [MailForwardAsAttachment] )
and for this you have to be the editor of the document.
