Email, Spam Control, Email or attachment disappears
When sending email that contains an attachment to an @illinois.edu address the message disappears, but when sending to a non-University address the message is delivered.
As part of its efforts to protect the University from malware and other email threats, emails that are sent to @illinois.edu email addresses are scanned for known viruses. If an attachment contains a virus, the email is automatically deleted.
Note: Once an attachment is stripped, it is deleted and cannot be retrieved.
