Separating email and web hosting

Hi. I need a little direction on separating email and web hosting. My client has his domain/email/web hosted elsewhere and I’m talking over the web hosting and hosting it here on Dreamhost.

Q: What do I need to setup on the Dreamhost side and what do I need to provide my client’s IT support person to make it work?

Thanks in advance for any direction you can provide.

Fyi … here’s what I’ve done so far:

[]Added the domain name ( on Dreamhost
]Under “DNS” settings for, found the A record info
[*]Passed along the IP address for the WWW A record to the client’s IT Support person

Of course I’ll create the website content (via Wordpress) but, as far as separating web from email et al, is it that easy?
