With regard to procmail/spamassassin support I have the following recommendation, and it can be applied to both cyrus and dovecot (I think).
You do not mention what SMTP system you are using, I will assume you are sticking with sendmail and changing qpopper to some IMAP server. However, I would suggest you consider postfix in place of sendmail. And yes, it's very ready for mission critical.
There is a package called amavisd-new which allows you to set up an anti-virus scanner and spamassassin as an extension of postfix. This can process email before it's delivered from postfix to where ever (procmail/lmtp/...)

I am an exim-guy. ;-) But afaik this all is possible with sendmail, too, amavisd-new connects to sendmail's milter interface. /This/ is no reason to switch MTAs. cu andreas
True, amavis will work with sendmail or postfix equally well.
I find people familiar with sendmail stick with it. Those who are newer to email find postfix a little easier or more secure* or something that makes it more compelling.
- As I understand it, sendmail can be very insecure to someone who isn't paying attention to details.
