No functional change. + +TF/02 Improve the consistency of logging incoming and outgoing interfaces. + The I= interface field on outgoing lines is now after the H= remote + host field, same as incoming lines. There is a separate + outgoing_interface log selector which allows you to disable the + outgoing I= field. + +JH/02 Bug 728: Close logfiles after a daemon-process "exceptional" log write. + If not running log_selector +smtp_connection the mainlog would be held + open indefinitely after a "too many connections" event, including to a + deleted file after a log rotate. Leave the per net connection logging + leaving it open for efficiency as that will be quickly detected by the + check on the next write. + +HS/01 Bug 1671: Fix post transport crash. + Processing the wait- messages could crash the delivery + process if the message IDs didn't exist for some reason. When + using 'split_spool_directory=yes' the construction of the spool + file name failed already, exposing the same netto behaviour. + +JH/03 Bug 425: Capture substrings in $regex1, $regex2 etc from regex & + mime_regex ACL conditions. + +JH/04 Bug 1686: When compiled with EXPERIMENTAL_DSN_INFO: Add extra information + to DSN fail messages (bounces): remote IP, remote greeting, remote response + to HELO, local diagnostic string. + +JH/05 Downgrade message for a TLS-certificate-based authentication fail from + log line to debug. Even when configured with a tls authenticator many + client connections are expected to not authenticate in this way, so + an authenticate fail is not an error. + +HS/02 Add the Exim version string to the process info. This way exiwhat + gives some more detail about the running daemon. + +JH/06 Bug 1395: time-limit cacheing of DNS lookups, to the TTL value. This may + matter for fast-change records such as DNSBLs. + +JH/07 Bug 1678: Always record an interface option value, if set, as part of a + retry record, even if constant. There may be multiple transports with + different interface settings and the retry behaviour needs to be kept + distinct. + +JH/08 Bug 1586: exiqgrep now refuses to run if there are unexpected arguments. + +JH/09 Bug 1700: ignore space & tab embedded in base64 during decode. + +JH/10 Bug 840: fix log_defer_output option of pipe transport + +JH/11 Bug 830: use same host for all RCPTS of a message, even under + hosts_randomize.
