To help protect the Âé¶¹ÊÓÆµ network and its users, Âé¶¹ÊÓÆµ 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 Âé¶¹ÊÓÆµ email accounts.
When such an attachment is encountered, the Âé¶¹ÊÓÆµ 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.
