how can I tell postfix to send email from email clients from outside?

[jpganz]

Hi,

I used this great tutorial http://www.howtoforge.com/virtual-us...debian-squeeze to configure my emails , it works very nice, I changed few things, the problem now is that I want to use outlook to connect and read the emails, it connects and reads, but I can not send, I added

smtpd_recipient_restrictions = permit_sasl_authenticated

and I also added
mynetworks = 127.0.0.0/8 192.168.0.0/24

But still.. I get an error,I really dont know whats wrong, due this configurations myabe I need to do something more, any idea??

Thanks in advance.
