Email, Spam Control, Email or attachment disappears

When sending email that contains an attachment to an 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 email addresses are scanned for known viruses. If an attachment contains a virus, the email is automatically deleted.

Certain file types are automatically filtered; a list of those is available here: Spam Control, Attachment Filters. Archive file types (such as .zip) that contain more than 256 files or are more than 10 layers deep (folders within folders) are automatically filtered.

Q: I need to send or receive a file that is being filtered. What can I do?

A: The best way to send files is not through email attachments, but through Cloud-based supported file sharing services.
  • Note: Once an attachment is stripped, it is deleted and cannot be retrieved.
