RFC3921 #8.2 step #8 explicitly states that the original server should
silently drop the request in such a situation. Eg:
Tony at example.com ---subscribe---> Igor.Goryachev at example.com
This by way of aliasing gets resent to Igor at example.com .
You then approve Tony's subscription:
Igor at example.com ---subscribed---> Tony at example.com
However, Tony at example.com's internal roster has no knowledge of
Igor at example.com (ie, it asked Igor.Goryachev, not Igor), and
thus Tony's server immediately drops the packet without passing it
to Tony's client.
