This snipet was taken from :

Note: Mailguard=fixup protocol smtp 25
When configured, Mailguard allows only the seven SMTP minimum-required
commands as described in Section 4.5.1 of RFC 821 . These seven
minimum-required commands are: HELO, MAIL, RCPT, DATA, RSET, NOOP, and QUIT.
Other commands, such as KILL, WIZ, and so forth, are intercepted by the PIX
and they are never sent to the mail server on the inside of your network.
The PIX responds with an "OK" to even denied commands, so attackers would
not know that their attempts are being thwarted.

Santiago weather this good for your enviroment or not I can't really say.  I
was some installations where I run it and a few where I do not.

Good Luck
