Exchange server receiving tons of spam even with port blocked

#155292

I am my server running through spam soap.
The firewall is only to allow connections from spam soap IP on port 25.
I turned on the connection filter to allow from spam soap IP’s only.

I am still receiving spam, these are some header examples from the spam messages. Can you give me some ideas how to stop this and where its coming from? Seems like alot come from a .ru address.
