The main difference with cyrus and dovecot is that cyrus is always completely 
seperated from users. You can configure dovecot to use a mail storage in users 
home folder. This is not possible wit cyrus. And dropping mails in cyrus 
storage is not allowed. This has to be done with either lmtp protocol or the 
cyrus deliver program.

So there are several flows possible with dovecot:

- fetchmail/getmail
- deliver (dovecots deliver process includes sieve filtering)
- dovecot imap

or more complex (if you have no spam checking on your provider side):
- fetchmail/getmail
- procmail (filtering, spam and virus checking)
- dovecot

or full featured (that's the one I use - I don't need fetchmail/getmail as I 
have set up my own mail server)
- postfix (initial checks)
- amavisd (spam and virus check)
- postfix (final delivery via lmtp)
- cyrus lmtp (includes sieve filtering)
- cyrus imap

All have advantages and disadvantages. I started more than ten years ago with 
the second solution (with cyrus instead of dovecot) and slowly moved to the 
final solution (took almost five years).
