Hi

I am trying to use Postfix in my local network, but whenm i try to send a
mail to an user of a domain not managed by postfix, y get some errors like
this (from gmail):

===========================

============================

So i think (my knowledge is very small) that my domain (bytelecom.org) that
is not registered and i use only for tests, gmail can not trust it and
denies the message. So i want all my emails be sent using my ISP mail
server, who requires authentication. I have no idea this can be done. I have
some searches but i have not found any conclusion. Could you help me
(again). Thanks in advance.
