Where do you plan on receiving your mail?
If you're going to be logged in to the same Linux box that receives the
mail, you don't need POP3. Just let sendmail receive the messages.
They'll be deposited in various mailbox files under /usr/spool/mail.
Most mail programs (Mail, pine, elm, Netscape) can be configured to
fetch mail messages out of your local mail spool. (For Netscape, add a
"local movemail" server to the configuration.)
If you want to read the mail out of the Linux box from a remote
location, then a POP3 server might be useful. (or you could just
remotely login with ssh and run a text-based mail program from there...)
