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.
