FASmail and Interchange blocking some attachments โ€“ February 23, 2011

Email subscribers using FASmail and Interchange email may notice a behaviour change when sending messages with identified suspect attachments. The new UBC mail gateway is verifying the file type of any attachments, and blocking the message if it is an identified suspect attachment type. Although UBC has always blocked suspect attachment types, previously only the file extension was used. It is no longer possible to send suspect attachment types in .zip archives, or through other workarounds. UBC IT is currently evaluating this mail gateway behaviour, and updates will be provided on the UBC IT Bulletins site.
