Windows IIS SMTP Test Scripts

I wrote a couple of Autoit scripts to test if a Windows IIS SMTP server is responding properly.

The first is [download#4]. This guy connects to the local mail relay and sends an email. Simple. You supply it with three command line parameters: from address, to address and subject.

The second, called [download#3], checks the mail queue folder (“c:\Inetpub\mailroot\Queue\”) and if it has any files older than 12 minutes, it restarts the relay service. If you have mail to send and your server looses connectivity to the DNS server, it will generally freak out and start leaving mail in the queue. By restarting the service, the mail will then flush out of the queue.

You will want to schedule the testSMTP script to run, say, once a day. It will send you an email letting you know you are still able to send out the server. This is great for critical monitoring servers. You will want to schedule the mailRoot script to repeat every 30 minutes or so.
