Deleting e-mails on mailserver from Outlook2000 using POP3

I am using outlook2000 with pop3 account. I have configured pop3 to keep
messages on server because I access same e-mail account from different
computer . However, I've noticed when e-mail is deleted from an Inbox,
deletion does not affect server's e-mail, leaving the e-mail undeleted.
This results in deleted mail being downloaded when I am using a
different computer. How can I do this so only undeleted e-mails are kept
on server side when using pop3 protocol?
Sorry, there isn't IMAP protocol being supported and no plan to support
it in the future.
