Hi guys
I do not how but It's obvious that unfortunately my domain has been infected by SPAM. I use "IP Block List Provider" and "content filtering" but I don't know how it happened. I set RCL 4 for quarantine, RCL 6 for reject and RCL 8 for delete messages.
any way, at the moment the issue is some IP Block List Providers mark our emails as spam and reject them or send them to Junk box. How can I make my domain clear?
I have exchange 2010 and have installed all roles on one server. Server is 2008 R2 and I don't have any ant virus on it (for some reasons).
