Either your servers are/were severely misconfigured, or you don't mean the same thing as I when you talk about blocking. block == reject with 5xx error code in the SMTP transaction. Or possibly block at firewall level. So it's the task of the upstream mailserver to generate a bounce (and since the upstream mailserver in most cases belongs to the administrative domain where the mail originally comes from, there's fair chance that the bounce actually gets to the sender of the mail.) How did your users not receive a bounce? (... and users not able to read bounce messages are a different topic, of course ...) > Finally, I keep postmaster always open, a thing that a lot of this > happy blocking servers does not. Goes without saying. Additionally, as I said, the rejection message does contain a unblocked email address, too. So far, postmaster and abuse are not spammed. cheers -- vbi -- Computer analyst to programmer: "You start coding. I'll go find out what they want."
