If your speaking of eliminating Spam from your email there are several vendors, GFI and TrendMicro come to mind, that have products integrated with Exchange 2k that work well.  

You can also block IP's and domains in Exchange manually which it sounds like your doing already.

Am I understanding the question correctly?

What do you mean by "it does received the spam attacks?"  Disabling relay doesn't mean that spammers won't <u>try</u> to send spam through your server.  It just means that your server won't forward non-local messages to other servers.

Ok i now my server doesn´t relay, i´ve tested over and over again, but the point is that still accept huge massive lists of e-mails to be relayed, but it does´n't send them away, and with several relayed test utilities i get these message:

From: spamtest@server.glypa.com
<<< 250 2.0.0 Resetting
>>>> MAIL FROM:
<<< 250 2.1.0 spamtest@server.glypa.com....Sender OK
>>>> RCPT TO:<"tabaco@whitepuma.net">
<<< 250 2.1.5 "tabaco@whitepuma.net"@cygla.com
>>>> DATA
<<< 354 Start mail input; end with .
>>>> MESSAGE
<<< 250 2.6.0 Queued mail for delivery
SUCCESS

Relay Accepted - final response code 250

If you dont recieve it then its not a relay (Its still a Bad Thing (TM) that it accepted)

do you know a way to stop this from happening....
