Once my in.mbx gets deleted, Eudora and Kaspersky seem to combine to
eat my incoming email messages, so I lose not only what I have
accumulated in my "in" mailbox (which is nothing now!), but all my
incoming mail for the day.

Try it. Your KAV 4.x key file should work with KAV 5.0 as well.
If Kaspersky still scans my email messages after that, I may remove it
from my system completely.
To test this, install KAV 5.0. Disable it from the system tray. Send
yourself an e-mail with an Eicar Test file in it (see
www.eicar.org)
and immediately close your e-mail app after the Eicar mail left your
outbox. Switch KAV 5.0 e-mail scanning back on. Retrieve your e-mails,
now your Eicar test mail should be retrieved from your POP3 account
and immediately removed by KAV 5.0, without deleting your complete
Eudora inbox.
