Disconnect the server from the internet?

I suppose you have to start with reading up on spam protection and SMTP protocol in general.

Then set up:
Spam filtering software (bayesian filters)
SMTP sanity checks (address checks etc)
RBLs (block access from DSL accounts etc)
greylisting (temporarily block unknown senders)

If you don't know what any of these are, see the first two lines.
