Root cause: the fix dated 20141018 + for the Postfix Milter client was incomplete. The client + did correctly hide the first, Postfix-generated, Received: + header when sending message header information to a Milter + with the smfi_header() application callback function, but + it was still hiding the first header (instead of the first + Received: header) when handling requests from a Milter to + delete or update an existing header. Problem report by + Carlos Velasco. This change was verified to have no effect + on requests from a Milter to add or insert a header.

File: + smtpd/smtpd.c. + +20240209 + + Performance: eliminate worst-case behavior where the queue + manager defers delivery to all destinations over a specific + delivery transport, after only a single delivery agent + failure.

Files: *qmgr/qmgr_deliver.c. + +20240226 + + Safety: drop and log over-size DNS responses resulting in + more than 100 records. This 20x larger than the number of + server addresses that the Postfix SMTP client is willing + to consider when delivering mail, and is well below the + number of records that could cause a tail recursion crash + in dns_rr_append() as reported by Toshifumi Sakaguchi.
