Postmaster

[Bgoines]

We have a Fortimail 100c deployed as a gateway with an exchange server. I get an average of 30 emails/day from postmaster@mydomain.net. These are delivery notifications of failed emails that I have not sent. I have opened a case with Fortinet but they have not been able to resolve the issue. Does anyone have any ideas how to stop this other than disabling my email address?

Thank you in advance!!

are you trying to stop the DSN? or do you want to eliminate the poastmaster@mydomain.net?

To change the email address & to disable see image.

I would like for the false emails from being sent. If I disable DSN, wouldn't that eliminate "legitimate" notices from being sent/received?

So the postmaster@mydomain.net is external and spoof'd going to you or a user? If it's from  the same sender, just write a rule to block it.
