Instead, proxy the child (and any subsequent ones) for TLS via a unix-domain socket channel. Logging is affected: the continued delivery log lines do not have any DNSSEC, TLS - cipher, Certificate or OCSP information. + Certificate or OCSP information. TLS cipher information is still logged. JH/04 Shorten the log line for daemon startup by collapsing adjacent sets of identical IP addresses on different listening ports.

Since we + currrectly use a new context for every connection, both as server and + client, there is no benefit for these. + GnuTLS appears to not support tickets server-side by default (we don't + call gnutls_session_ticket_enable_server()) but client side is enabled + by default on recent versions (3.1.3 +) unless the PFS priority string + is used (3.2.4 +). + +PP/03 Add $SOURCE_DATE_EPOCH support for reproducible builds, per spec at + . + +JH/07 Fix smtp transport use of limited max_rcpt under mua_wrapper.

In the + case where the routing stage had gathered several addresses to send to + a host before calling the transport for the first, we previously failed + to close down TLS in the old transport process before passing the TCP + connection to the new process. The new one sent a STARTTLS command + which naturally failed, giving a failed delivery and bloating the retry + database.

Previously there were + false-negatives in the check that the sender had not preempted a response + or prompt from Exim (running as a server), due to that code's lack of + awareness of the SMTP input buferring. + +PP/04 Add commandline_checks_require_admin option. + Exim drops privileges sanely, various checks such as -be aren't a + security problem, as long as you trust local users with access to their + own account.
