Question

How to tell if I am sending spam

Asked by: jasdak

Below is the typical form of an email that i get in bursts every now and then.  i have hosted on my lan a SBS 2003 R2 server with exchange running.  i also have a service that hosts my other company's email off site.  i am wondering if this means that somehow my server is sending spam out.  i thought that i had correctly tested to see if i was an open relay and i thought that it showed i was safe.  please let me know if this is an indication of something bad.  i can provide more info if you need it.  thanks.

            The e-mail system was unable to deliver the message, but did not report a specific reason.  Check the address and try again.  If it still fails, contact your system administrator.

That indicates that you are sending to an invalid email address. It's not because of spam because at the RCPT TO phase of the email conversation they have not yer even seen your message itself.

but why would it be that i am getting 10-20 of these per day and they are all odd addresses that no one in my company is sending to?  thanks for the quick reply!

Then you are getting Joe-Jobbed: someone is using your domain in their return path. There's no real concern if you can verify that you didn't sent the original message and nothing you can do about it.
