Standard Node vs Remote Base
Specifying a Standard Node and a Remote Base Node in rpt.conf
In the nodes stanza, a remote base node is denoted when it is suffixed with a y option:
[nodes] 1234 = firstname.lastname@example.org/1234,NONE,y ; Remote base node 5678 = email@example.com/5678,NONE ; Standard node
In the above example node 1234 is a remote base node, and node 5678 is a standard node.
