Messages from= and pflogsumm
Hello, In the logs, there are cases where some message seems to be coming from=. This seems to be happening when local Postfix returns some delivery report to sender (sender delivery status notification). In such cases PFLOGSUMM, instead of a domain name or full sender address, displays in the stats from=. Here are some examples: Host/Domain Summary: Messages Received --- msg cnt bytes host/domain --- --- ... 1 1875 somehost.noa.gr 1 1850 from= 1 1806 chandler.mit.edu ... Senders by message count ... 44 us...@noa.gr 43 from= 42 us...@example.org ... Senders by message size --- ... 1936k us...@example.gr 1724k from= 1633k us...@example.gr ... Is it intended behavior? Or in such cases, pflogsumm could report using some pre-set term e.g. localhost (or the server domain name) and local-mailer@localhost (or even better the actual address used by postfix when delivering reports - see below) respectively? Note: In our system, I see that delivery notifications (Successful Mail Delivery Report) seem to be coming from: Mail Delivery System mailer-dae...@noa.gr Can I customize this in Postfix? Thanks and best regards, Nick

[snip] In such cases PFLOGSUMM, instead of a domain name or full sender address, displays in the stats from=. That's because the sender is the null sender. So it was either display nothing at all, or show from= to make it clear those were from the null sender. [snip] Is it intended behavior? [snip] Yes.
