1- I may receive a lot of DoS or dictionary attacks, I want to install the webmail and the SMTP server on different networks and HW. Can iRedmail admin manage this?
No. But how about installing iRedMail on each server, then disable services you don't want? It's easy.

2- Instead of Dovecut, can I use Cyrus IMAP server? Cyrus has a very nice scalability architecture with proxies. If this is not possible, can a custom solution be developed?
No plan for Cyrus POP3/IMAP server, sorry.
