SBS 2003 Open Relay Help

Posted on 2008-10-17
Last Modified: 2013-11-30
Recently, all of the sudden our systems were running extremely slow, and email wasn't being sent out.  It was discovered that our SBS 2003 server had been somehow switched to an open relay!  I quickly went and mad the necessary changes in the ESM to get it back, but our systems are still running slow and there are messages still appearing in the SMTP queue.  Is it possible that I have to restart my server for these changes to take effect or am I just receiving the residual mail that was being relayed?

Any help is appreciated.

I'm going through that process right now.  The problem is that as I'm deleting the 5000 or so messages in the queue, another 5000 pop up.  I can' tell if these are new messages that are coming through or not.

Ok.  You are probably just working the residuals. :)

You just have to restart the smtp service. it should stop the unwanted users of relaying trough your smtp server.

It appears that it is in fact the residuals I'm receiving, there is just a ton.  Does anyone know of an alternate place to get the aqadmcli.exe file from?  The microsoft links will not work.

If the mail is sitting in the SMTP queue, you can stop the SMTP virtual
server and then delete the files in the queue directory on the disk.
After that just restart the virtaul SMTP server again.
