Hi Holger,

Suppose a group of people have recently met and exchanged email
addresses, and are now engaged in time-sensitive communication.

As an outsider, I can send an email to the group containing incorrect
gossip for the group.  This has a fair chance of disrupting
inter-group communication, causing confusion and delay.
