Hello. I have an Ubuntu 9.04 server with postfix/courier installed. Last week I had thousands of spam in mailq and alot of connections on port 25. I got on many blacklists and I try to get rid of this problem.
My configuration is pretty tight and I am not an open relay. Can you tell me please what should I do? Last time happened 5 days ago, I just closed port 25 and cleared the mailq and added some stuff at "smtpd_recipient_restrictions" but now it happened again. If my server isn't an open relay, how could this happen?
Here's my configuration and some text from the logs

My configuration is pretty tight and I am not an open relay. Can you tell me please what should I do? Last time happened 5 days ago, I just closed port 25 and cleared the mailq and added some stuff at "smtpd_recipient_restrictions" but now it happened again. If my server isn't an open relay, how could this happen?
Here's my configuration and some text from the logs
