Change log file for Exim from version 4.21
-------------------------------------------
-Exim version 4.81
+Exim version 4.82
-----------------
PP/01 Add -bI: framework, and -bI:sieve for querying sieve capabilities.
JH/09 Add $headers_added variable, with content from use of ACL modifier
add_header (but not yet added to the message). Bugzilla 199.
+JH/10 Add 8bitmime log_selector, for 8bitmime status on the received line.
+ Pulled from Bugzilla 817 by Wolfgang Breyha.
+
+PP/11 SECURITY: protect DKIM DNS decoding from remote exploit.
+ CVE-2012-5671
+
+JH/11 Add A= logging on delivery lines, and a client_set_id option on
+ authenticators.
+
+JH/12 Add optional authenticated_sender logging to A= and a log_selector
+ for control.
+
+PP/12 Unbreak server_set_id for NTLM/SPA auth, broken by 4.80 PP/29.
+
+PP/13 Dovecot auth: log better reason to rejectlog if Dovecot did not
+ advertise SMTP AUTH mechanism to us, instead of a generic
+ protocol violation error. Also, make Exim more robust to bad
+ data from the Dovecot auth socket.
+
+TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
+
+ When a queue runner is handling a message, Exim first routes the
+ recipient addresses, during which it prunes them based on the retry
+ hints database. After that it attempts to deliver the message to
+ any remaining recipients. It then updates the hints database using
+ the retry rules.
+
+ So if a recipient address works intermittently, it can get repeatedly
+ deferred at routing time. The retry hints record remains fresh so the
+ address never reaches the final cutoff time.
+
+ This is a fairly common occurrence when a user is bumping up against
+ their storage quota. Exim had some logic in its local delivery code
+ to deal with this. However it did not apply to per-recipient defers
+ in remote deliveries, e.g. over LMTP to a separate IMAP message store.
+
+ This change adds a proper retry rule check during routing so that the
+ final cutoff time is checked against the message's age. We only do
+ this check if there is an address retry record and there is not a
+ domain retry record; this implies that previous attempts to handle
+ the address had the retry_use_local_parts option turned on. We use
+ this as an approximation for the destination being like a local
+ delivery, as in LMTP.
+
+ I suspect this new check makes the old local delivery cutoff check
+ redundant, but I have not verified this so I left the code in place.
+
+TF/02 Correct gecos expansion when From: is a prefix of the username.
+
+ Test 0254 submits a message to Exim with the header
+
+ Resent-From: f
+
+ When I ran the test suite under the user fanf2, Exim expanded
+ the header to contain my full name, whereas it should have added
+ a Resent-Sender: header. It erroneously treats any prefix of the
+ username as equal to the username.
+
+ This change corrects that bug.
+
+GF/01 DCC debug and logging tidyup
+ Error conditions log to paniclog rather than rejectlog.
+ Debug lines prefixed by "DCC: " to remove any ambiguity.
+
+TF/03 Avoid unnecessary rebuilds of lookup-related code.
+
+PP/14 Fix OCSP reinitialisation in SNI handling for Exim/TLS as server.
+ Bug spotted by Jeremy Harris; was flawed since initial commit.
+ Would have resulted in OCSP responses post-SNI triggering an Exim
+ NULL dereference and crash.
+
+
+Exim version 4.80.1
+-------------------
+
+PP/01 SECURITY: protect DKIM DNS decoding from remote exploit.
+ CVE-2012-5671
