Email/ Zip rejected mail page

Why have I been directed to this page?

You have been directed to this page because the University of Bristol's mail system has rejected a message sent by you. The message was rejected because it contained an executable file contained within a ZIP file.

Why do you block executable files contained within ZIP files?

We regret the inconvenience this causes; however, we estimate that 99% of mail blocked by this policy is malicious software.

Using executable files within ZIP files is a method of bypassing mail filtering, and is increasingly used by viruses and worms, and while the University performs virus scanning on all incoming email, there is always a window of opportunity between a virus being released and anti-virus software companies updating their products to detect it. Our policy on blocking suspicious attachment types is designed to address this risk.

My file is legitimate. How do I get it to its intended recipient?

One method would be to provide the file to its recipient using a route other than email. For example, put the file on a web server and send the recipient a link to the file.

The University provides a service called the Facility for the Upload of Large Files (fluff), which allows the distribution of files via the web, and it is possible for external users to be granted access to upload files there for the attention of a member of the University.

If you wish to use this method, please ask the intended recipient of the file to request a ‘fluff guest authentication URL’ for you; they can obtain this via the fluff guest registration form

Once you have a guest authentication URL, you can use it to upload files for the recipient at any point within 7 days of it being created. The uploaded files will be accessible by the recipient for a period of up to 14 days from the time of upload.
