Hi,

The great mind that should answer is Rein but I'll try to say something...
Clients and servers send their beacons the same way with a position packet.
A server that receives a position can not see whether the transmission
was sent from a client or a server so it will send a QSL.
When other servers receive that QSL, like QSL KB2PNM de KB1NCJ, they
will realize that KB1NCJ is in fact a server.
That also happens when the server hears another server answer a ping or
ack an aprs message.
The server callsign is added to an array and the next time it hears a
packet it will check if it originated from a known server, if so then it
does not send a QSL:

if (exists $servers{$1}) {
    # do nothing, its a server.
 } else {
...

That list of servers is loaded at startup from the internet if there is
a connection, those calls should be here:
{HOME}/.pskmail/.internetcalls

So, we should be able to add known servers manually...
