I've currently got an Exchange 2003 server and OWA. When I send mails
from this system some recipients never receive the mails because there
email systems (exchange 2000) blocks my mails as spam. Is there any
reason for this, is my exchange server adding/changing something on the
mails outbound.

Thanks for your help

Dear Yoda,

regarding to your post, please add more information of your current exchange
setup:

Q1- how many exchange servers your have ? do you have single Exchange Server
as Back-End which is also acting as OWA ?

Q2- does your exchange server has a public IP Address connected directly to
the internet without any firewall protection ? if this is the case, then your
exchange server is exposed to the enternet , and all the intruders from
outside is using your SMTP protocol on your exchange server to send spam
emails.

Q3- explain more about your current network in terms of security and firewall.

it seems that your public IP Address is being recognized as Spam creator IP
which sends spam emails . your Public IP was blocked internationally, please
check this with your ISP to resolve this issue.

waiting for your updated information.
