Hi filips,
Yes they are missed by antispam protection and received as legitimate NDRs, which is confusing for mail users.
How can I submit a support ticket?
Hi,
I'm using Eset Mail Security 6.3.10005.2 to protect an Exchange Server.
These days, I'm having issues with users receiving a bunch of fake NDR and I can't find a way to block or quarantine them.
Any ideas, please?
