Please bear with me, I am a newbie with mailing and postfix

Error: five five zero "unable to relay"

I have two Linux servers at a client. They are set up exactly the same,
but on the 1 the mail goes through (to external addresses), and on the
other one I get the error 550: unable to relay

Is there something in my config that I can do to let the mail go
through, or must the admin of the relay server change something on his
side to allow me to send mail through his relay server ?

Dirk

Apologies for the disclaimer as well. My mail goes through my work
address, and the disclaimer gets added by our exchange server.
