Disable POP/IMAP Allow Webmail and Open Relay

I am trying to set up our dedicated server to only allow folks to use the webmail system. We do not want anyone to be able to check mail with POP or IMAP outside of the webmail. Additionally we do need to be able to use the dedicated server as a relay for our systems on other servers - we need to do this with no SMTP authentication.

Is this all possible? Where do I start with the configuration. I know how to disable the pop and imap by blocking them through the firewall. However, I am not sure what this will do to the webmail functionality and also have not had any luck trying to use the SMTP relay as port 25 is blocked.

ANy help would be great.
