What does incoming mean?  From the point of view of the MTA (postfix) every 
external mail is incoming (either incoming from the Internet or incoming 
from your Intranet).

I only gave a fast look at the first tutorial you reference and it doesn't 
seem to make any difference: everything incoming by port 25 will go through 
the antispam system.

 Will give me spam/virus filtering for INBOUND or OUTBOUND
 mails? Or Both?  sorry for the question :D But I have to
 know it 100% sure.

Why not try it on a test system, and see? You could use the
EICARS test virus in an outbound mail to a test address and
see if it reaches it.

If you are planning to do spam+antivirus filtering, let me suggest you 
Amavisd-new to act as a glue for all the added services.

Postfix calls Amavisd-new and Amavisd-new calls both, SA and ClamAV and 
then reinjects the mail into Postfix.

IIRC, Postfix and Amavisd can be configured to perform both, inbound and 
outbound filtering, if required.
