I suspect Butch's suggestion will get you headed in the right direction,
but in the interim, looks to me like you attached the "ktrace" *after*
you'd already done the login to the Qpopper server via Telnet.
You want to attach it *as soon as you've made the initial Telnet connection
to the POP port*. As soon as you get the Qpopper greeting! *BEFORE* you
log in. I see nothing in your "kdump" output that shows the authentication
negotiation, or where Qpopper after authentication looked for your mail
spool file. You attached to it just before it dumped out the stats that
it found no messages.
