Separating Mail Web and maybe mysql

It wouldn't, but it also won't be that easy to set-up.... I would go this way:

mail.domain.tld
- Courier config (/etc/courier) database should be NFS exported
- So should be postfix config (/etc/postfix) with an aditional warning: ispcp will configure it as web.domain.tld fqdn so you will have to replace it manually.

web.domain.tld
- Mount /etc/courier & /etc/postfix from mail.domain.tld
- Modify DNS templates to point MX, mail, pop3, stmp, etc. to mail.domain.tld instead of web.tomain.tld

db.domain.tld
- This is the easiest of all, just enter the db server IP on ispcp installation (and tell your customers that they need to use "db.domain.tld" when connecting to their mysql databases)

Once this is all working you would get:
- Dedicated mail server that processes all mail including pop3/imap and authentication locally
- Dedicated db server (this is optional, you may choose to run this at the web machine)
- Web/panel/ftp server that manages the mail server through NFS access to it's config/userdbs files


This *might* work, but I'm sure that some problems will arise... be ready to fight a bit
