Problem with send/ receive mail in ISPconfig

is possible if I want to try "Postfix With SMTP-AUTH" in this tutorial "http://www.howtoforge.com/perfect-server-ubuntu-12.04-lts-apache2-bind-dovecot-ispconfig-3-p4"?
I want to try setting the SMTP-AUTH because so much spam mail activities in mail.log and efect my IP Mailserver blocked by the "spamcop.net, gmail.com (I can not send mail to Gmail with error: address has been blocked. 550 - 5.7.1 Please visit
http://www.google.com/mail/help/bulk_mail.html to review 550 5.7.1 our Bulk
and I also can not send to yahoomail ".

I've tried to follow the tutorial at this link about "Postfix With SMTP-AUTH And TLS" (http://www.howtoforge.com/perfect-server-ubuntu-9.04-ispconfig-2-p5) but it did not work at start fail .

root@test:/tmp# /etc/init.d/saslauthd status
* Checking SASL Authentication Daemon saslauthd [fail]
root@test:/tmp# /etc/init.d/saslauthd restart
* Stopping SASL Authentication Daemon saslauthd [ OK ]
* Starting SASL Authentication Daemon saslauthd /usr/sbin/saslauthd: invalid option -- ':'
usage: saslauthd [options]

option information:
-a <authmech> Selects the authentication mechanism to use.
-c Enable credential caching.
-d Debugging (don't detach from tty, implies -V)
-r Combine the realm with the login before passing to authentication mechanism
Ex. login: "foo" realm: "bar" will get passed as login: "foo@bar"
The realm name is passed untouched.
-O <option> Optional argument to pass to the authentication
mechanism.
-l Disable accept() locking. Increases performance, but
may not be compatible with some operating systems.
-m <path> Alternate path for the saslauthd working directory,
must be absolute.
-n <procs> Number of worker processes to create.
-s <kilobytes> Size of the credential cache (in kilobytes)
-t <seconds> Timeout for items in the credential cache (in seconds)
-v Display version information and available mechs
-V Enable verbose logging
-h Display this message.
