Brief Description:
User Impact:
When a message with one of these attached file types is refused, Cornell’s email systems will attempt to notify the sender. A "message not delivered" message will be sent, but some systems outside of Cornell’s control (the sender’s email service provider or email application, for example) may interfere with delivery of this notification by classifying it as junk, spam, or for some other reason. Cornell's messaging system automatically replies to the sender when a message cannot be delivered, but the complexity of email ecosystems can sometimes block our efforts.
There is no workaround for this issue

Full Description:
