- update to exim 4.93.0.4 (+fixes release)
* Avoid costly startup code when not strictly needed. This reduces time
for some exim process initialisations. It does mean that the logging
of TLS configuration problems is only done for the daemon startup.
* Early-pipelining support code is now included unless disabled in Makefile.
* DKIM verification defaults no long accept sha1 hashes, to conform to
RFC 8301. They can still be enabled, using the dkim_verify_hashes main
option.
* Support CHUNKING from an smtp transport using a transport_filter, when
DKIM signing is being done. Previously a transport_filter would always
disable CHUNKING, falling back to traditional DATA.
* Regard command-line receipients as tainted.
* Bug 340: Remove the daemon pid file on exit, whe due to SIGTERM.
* Bug 2489: Fix crash in the "pam" expansion condition. It seems that the
PAM library frees one of the arguments given to it, despite the
documentation. Therefore a plain malloc must be used.
* Bug 2491: Use tainted buffers for the transport smtp context. Previously
on-stack buffers were used, resulting in a taint trap when DSN information
copied from a received message was written into the buffer.
* Bug 2493: Harden ARC verify against Outlook, whick has been seen to mix
the ordering of its ARC headers. This caused a crash.
* Bug 2492: Use tainted memory for retry record when needed. Previously when
a new record was being constructed with information from the peer, a trap
was taken.
* Bug 2494: Unset the default for dmarc_tld_file. Previously a naiive
installation would get error messages from DMARC verify, when it hit the
nonexistent file indicated by the default. Distros wanting DMARC enabled
should both provide the file and set the option.
Also enforce no DMARC verification for command-line sourced messages.
* Fix an uninitialised flag in early-pipelining. Previously connections
could, depending on the platform, hang at the STARTTLS response.
* Bug 2498: Reset a counter used for ARC verify before handling another
message on a connection. Previously if one message had ARC headers and
the following one did not, a crash could result when adding an
Authentication-Results: header.
* Bug 2500: Rewind some of the common-coding in string handling between the
Exim main code and Exim-related utities. The introduction of taint
tracking also did many adjustments to string handling. Since then, eximon
frequently terminated with an assert failure.
* When PIPELINING, synch after every hundred or so RCPT commands sent and
check for 452 responses. This slightly helps the inefficieny of doing
a large alias-expansion into a recipient-limited target. The max_rcpt
transport option still applies (and at the current default, will override
the new feature). The check is done for either cause of synch, and forces
a fast-retry of all 452'd recipients using a new MAIL FROM on the same
connection. The new facility is not tunable at this time.
* Fix the variables set by the gsasl authenticator. Previously a pointer to
library live data was being used, so the results became garbage. Make
copies while it is still usable.
* Logging: when the deliver_time selector ise set, include the DT= field
on delivery deferred (==) and failed (**) lines (if a delivery was
attemtped). Previously it was only on completion (=>) lines.
* Authentication: the gsasl driver not provides the $authN variables in time
for the expansion of the server_scram_iter and server_scram_salt options.
