The mail client (Evo, Kmail etc) then points to the local IMAP store?

This is the type of functionality I'm after.

We go at a slow pace with nothing on computer being "mission critical"
so I'm happy to stay with Fedora for now while I'm still learning, but

So the flow is:
ISP -> fetchmail -> postfix/procmail/sendmail -> MailScanner -> SQLGrey
-> Cyrus/Dovecot -> Evo/KOffice/etc
