exchange eventid 7010 - MSExchangeTransport

i had a relay attack last week and my exchange queues were been filled up, i have seemly resolved this issue.
However, in the event log im getting loads of eventid errors as shown below.
Does this mean im still having a problem?

Event Type:      Error
Event Source:      MSExchangeTransport
Event Category:      SMTP Protocol
Event ID:      7010
Date:            28/04/2010
Time:            11:08:09
User:            N/A
Computer:      GPSSERVER
This is an SMTP protocol log for virtual server ID 1, connection #172391. The client at "" sent a "rcpt" command, and the SMTP server responded with "550 5.7.1 Unable to relay for  ". The full command sent was "rcpt TO:<>".  This will probably cause the connection to fail.

Check your queues - are they still filling up?
If they are - you have not solved the problem so have a read of my article and see if that helps:'t-send.html

hi, the quese are not filling up now,
they only mails in there are valid  mails.
However i am having probs sending emails, some emails NOT ALL are not leaving email queue,
and  a couple are been coming back as undelivered.
I check blacklisting sites but i dont seem to be listed.
hence i was looking at logs and found the above eventid message, so was thinking it may effect smptp mail, however i saw i post where someone said this shows that exchange is working and blocking bad email.
Hope someone can help.

Create a reliable backup. Make sure you always have dependable copies of your data so you can restore your entire system or individual files.

The message is a rejection for an attempt to relay via your server, so that is working properly.
Do you use any Anti-Spam software on your server?
cstephen100Author Commented:
at present there is no anti spam on server to be honest,
incoming mail was  been screened by a third party.

You might want to consider a 30-day trial of Vamsoft ORF -
A brilliant bit of software (4Mb) and great at eliminating spam.
So essentially - you are good to go.  My 2nd article should hopefully help with the few domains that you can't send to.
If you get stuck - please let me know.
