sendme messages are generated by inews in response to an ihave message.
The code which process ihave's generates the sendme directly from the
ihave message itself.  After the header is processed, the message
body is read.  Each line is checked to see if the article is presently
on the system and if it is, the line is dropped, otherwise that message
id is copied from the ihave message to the sendme message.  So, in
short, if you are seeing sendme messages from ns to umn-cs it is because
there are ihave's coming from umn-cs.

The format of the messages may be what is confusing.  If two systems
are running ihave/sendme, the ihave message from machine abc has the
the line

Control: ihave abc

which machine xyz then replies to with

Control: sendme xyz

Also, if you have specified ihave/sendme in your sys file with the I
flag, you will be sending ihave messages to your neighbor.
