If I sent two emails using the same email service, with identical subjects, attachements, etc... the email sent with Applemail doesn't show any of the attachments when I log into @PrintByXerox on the copiers while the other email sent via the webmail client does. I get the same results whether the attachment is jpeg, PDF, or DOCX.
The devices are all VersaLink C7025s running software version 57.31.81. I'm not sure how to find the @PrintByXerox version number.
