What I got caught on was "client," altho from the context,
here ``client'' seems to mean the mail-server-sending-spam.'
In the unix world, my server is the client--unless the
client-server model is different with email. Another reason

to <= 15 minutes seems closert to what a spammer just wouldn't
bother with. Thanks for your insights!
