Exim version 4.86
-----------------
JH/01 Bug 1545: The smtp transport option "retry_include_ip_address" is now
expanded.
JH/02 The smtp transport option "multi_domain" is now expanded.
JH/03 The smtp transport now requests PRDR by default, if the server offers
it.
JH/04 Certificate name checking on server certificates, when exim is a client,
is now done by default. The transport option tls_verify_cert_hostnames
can be used to disable this per-host. The build option
EXPERIMENTAL_CERTNAMES is withdrawn.
JH/05 The value of the tls_verify_certificates smtp transport and main options
default to the word "system" to access the system default CA bundle.
For GnuTLS, only version 3.0.20 or later.
JH/06 Verification of the server certificate for a TLS connection is now tried
(but not required) by default. The verification status is now logged by
default, for both outbound TLS and client-certificate supplying inbound
TLS connections
JH/07 Changed the default rfc1413 lookup settings to disable calls. Few
sites use this now.
JH/08 The EXPERIMENTAL_DSN compile option is no longer needed; all Delivery
Status Notification (bounce) messages are now MIME format per RFC 3464.
Support for RFC 3461 DSN options NOTIFY,ENVID,RET,ORCPT can be advertised
under the control of the dsn_advertise_hosts option, and routers may
have a dsn_lasthop option.
JH/09 A timeout of 2 minutes is now applied to all malware scanner types by
default, modifiable by a malware= option. The list separator for
the options can now be changed in the usual way. Bug 68.
JH/10 The smtp_receive_timeout main option is now expanded before use.
JH/11 The incoming_interface log option now also enables logging of the
local interface on delivery outgoing connections.
JH/12 The cutthrough-routing facility now supports multi-recipient mails,
if the interface and destination host and port all match.
JH/13 Bug 344: The verify = reverse_host_lookup ACL condition now accepts a
/defer_ok option.
JH/14 Bug 1573: The spam= ACL condition now additionally supports Rspamd.
Patch from Andrew Lewis.
JH/15 Bug 670: The spamd_address main option (for the spam= ACL condition)
now supports optional time-restrictions, weighting, and priority
modifiers per server. Patch originally by <rommer@active.by>.
JH/16 The spamd_address main option now supports a mixed list of local
and remote servers. Remote servers can be IPv6 addresses, and
specify a port-range.
JH/17 Bug 68: The spamd_address main option now supports an optional
timeout value per server.
JH/18 Bug 1581: Router and transport options headers_add/remove can
now have the list separator specified.
JH/19 Bug 392: spamd_address, and clamd av_scanner, now support retry
option values.
JH/20 Bug 1571: Ensure that $tls_in_peerdn is set, when verification fails
under OpenSSL.
JH/21 Support for the A6 type of dns record is withdrawn.
JH/22 Bug 608: The result of a QUIT or not-QUIT toplevel ACL now matters
rather than the verbs used.
JH/23 Bug 1572: Increase limit on SMTP confirmation message copy size
from 255 to 1024 chars.
JH/24 Verification callouts now attempt to use TLS by default.
HS/01 DNSSEC options (dnssec_require_domains, dnssec_request_domains)
are generic router options now. The defaults didn't change.
JH/25 Bug 466: Add RFC2322 support for MIME attachment filenames.
Original patch from Alexander Shikoff, worked over by JH.
HS/02 Bug 1575: exigrep falls back to autodetection of compressed
files if ZCAT_COMMAND is not executable.
JH/26 Bug 1539: Add timout/retry options on dnsdb lookups.
JH/27 Bug 286: Support SOA lookup in dnsdb lookups.
JH/28 Bug 1588: Do not use the A lookup following an AAAA for setting the FQDN.
Normally benign, it bites when the pair was led to by a CNAME;
modern usage is to not canoicalize the domain to a CNAME target
(and we were inconsistent anyway for A-only vs AAAA+A).
JH/29 Bug 1632: Removed the word "rejected" from line logged for ACL discards.
JH/30 Check the forward DNS lookup for DNSSEC, in addition to the reverse,
when evaluating $sender_host_dnssec.
JH/31 Check the HELO verification lookup for DNSSEC, adding new
$sender_helo_dnssec variable.
JH/32 Bug 1397: Enable ECDHE on OpenSSL, just the NIST P-256 curve.
JH/33 Bug 1346: Note MAIL cmd seen in -bS batch, to avoid smtp_no_mail log.
JH/34 Bug 1648: Fix a memory leak seen with "mailq" and large queues.
JH/35 Bug 1642: Fix support of $spam_ variables at delivery time. Was
documented as working, but never had. Support all but $spam_report.
JH/36 Bug 1659: Guard checking of input smtp commands again pseudo-command
added for tls authenticator.
