Cyrus is used to *serve* POP3/IMAP from your machine. If you aren't checking
mail that is delivered to your box, you're not using it and can most likely
get rid of it.
If you're running a mail server, then it's usually useful to get the mail
back off, in which case you could use Cyrus, Dovecot, or any number of other
POP3/IMAP servers.
Hope that clarifies...
