Did I Close Open Relay Properly on Exchange SBS 2003 R2

my public static ip got blacklisted.  i checked my exchange sbs 2003 r2 server for open relay and turned on logging.  I noticed that a lot of other public ip's were doing open relay.  I turned some settings to turn open relay off and was wondering if the enclosed log shows that outside public ip's are no longer able to open relay via my server.  I included quite a few lines of the log above and below the time when i turned the open relay settings off.  thanks!

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.
