Hello,

my name is Gerard Verhoeven. For some time now I'm trying to gain experience
with Linux. I've build a server-system with an application written in PHP
and using Apache and Mysql to automate the administration of a shop. I used
a distribution from SUSE (version 8.0). This installation had SENDMAIL as
the mail-server, my application only uses it for outgoing mail. When a user
from the web wants to send a message, the PHP program uses the mail-function
and sends the message to discserviceplanet.nl. The mailserver from PLANET
is mail.planet.nl and I used masquerading to let PLANET accept my system
(uitleen.viavia). Maybe it is not the best solution, but it worked and I was
happy.
But after the update to SUSE 9.1, POSTFIX was the 'standard' mailserver. So
now I'm trying to make Postfix behave as Sendmail did, but it won't work as
you can see from the following part from the mail logile:

I would appreciate it very much if I could get the information necessary to
make this work or, if needed, a description of a better solution.

Thanks in advance for all the help that I get,

Gerard Verhoeven.
