I’m currently receiving the notification emails if there are any problem with our email server (eg. inbound and outbound mail failures etc).
I noticed that on some of the outbound mail failures, the sender is using a different email address instead of the organizations’ email address – since the sender’s email address is anonymous (eg. jg8983@othersite.com), I don’t know if this is an actual user in the organization.
Is this a security breach I’m looking at here?
How do I track/trace it??
Thanks.
