Does the rejecting SMTP server send the NDR based on actual header data or the spoofed from address?NO, the rejecting server rejects it, meaning door slammed go away. snarf0101 (4/21/2008)
With the nobody alias resolved to root-NUL, the invalid messages are just dropped. No dictionary attacks or backscatter.But that means your server will now spend time and resources accepting, processing AND THEN deleting the junk mail to non-existant users. Why do you want your server to do all that extra work? And believe me, the volume of incoming email will only increase. snarf0101 (4/23/2008)
So, you are fully correct that its really not my problem if my server sends the NDRs. NO, your server is NOT sending the NDRs. snarf0101 (4/23/2008)
We are getting more and more clients on our servers who are getting their email address spoofed.You can not stop that, but you can use SPF records to lessen it.
