To help protect the IUP network and its users, IUP does not permit delivery of email messages that contain high-risk attachments. Email messages that contain attachments of any of the file types noted below will not be delivered to IUP email accounts.
When such an attachment is encountered, the IUP email system will return the message to the sender with a note reporting that the message cannot be delivered because it contains a restricted attachment.
Please note that if you include a file of these types in a ZIP file, even though you rename the ZIP file per the renaming note, the attachment will still not send.
