Don't you just love it. Someone sent me a file today which got blocked. Here is the accompanying email from the IT department which they added to the mail....
This email contained a .zip attachment, so all attachments have been removed. XXXXXXX does not allow emails with .zip attachments. Please follow the instructions below to receive the files that were removed.
+ Contact the sender to rename the file, (e.g., change filename.zip to filename.rtnzip) and resend.
+ When you receive the file, change the name back to filename.zip.
Should you have any questions or difficulty with these instructions, please contact the Help Desk for assistance.
