Spam Strategies

[xencore]

We are currently receiving a large amount of "mail undelivered" spam to one of our domains.

My concern is that our SMTP on the domain is being used to send these spam messages - without our knowledge.

Is there a way to verify what is happening and where these emails are actually being sent form.

Appreciate and info on this.

You'd need to check the mail headers to see what is going on. In all likelihood you are being Joe Jobbed ie. someone is using your email address as the "reply to" for mails, however you'd need to doublecheck that to be 100% sure.
