Just to clarify how the new anti-virus feature works: mail coming
into is scanned for viruses.  When a virus is detected,
the sender's e-mail service is notified that delivery has been

If you send mail through using an e-mail client
such as Eudora or Outlook, each message will be scanned for
viruses.  Viruses such as Sobig that try to send through will also face virus detection and blocking.

However, if you are using the Webmail client for
to send mail, that mail will not be scanned for viruses due
to the current architecture of the system.  The mail team is
looking into adding scanning to outbound Webmail messages.

Based on the numbers so far and the nature of how Sobig,
Klez and the like are commonly spread, the system should
help contain future such outbreaks.

Again, we continue to strongly suggest use of anti-virus
software on individual computers.
