This comes straight out of my inetd.conf file on Slackware 7.1
I presumed Patrick Volkerding knew what he was talking about.
Maybe he blurred the lines a little- I just did not question it.

I quote:

" #pop3 stream tcp nowait root /usr/sbin/tcpd gnu-pop3d
  # The ipop3d POP3 server is part of the pine distribution. If you've
  # installed the pine package, you may wish to switch to ipop3d by
  # commenting out the pop3 line above, and uncommenting the pop3d line
  # below.
  #pop3 stream tcp nowait root /usr/sbin/tcpd ipop3d" <---* this line **

I did this on my SuSE 6.4 box.
I dont run fetchmail or imap ( I dont personally need them).
I can now get mail from my mail server from any other machine on my
network.
Yes, you can delete one message and leave the rest.

I just would not want this available out to the internet.

What more can I say :)
