Fix DK spooling code so that it can overwrite a + leftover -K file (the existence of which was triggered by #402). + While we were at it, introduced process PID as part of the -K + filename. This should rule out race conditions when creating + these files. + +TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing + processing considerably. Previous code took too long for large mails, + triggering a timeout which in turn triggers #401. + +TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used + in the DK code in transports.c. sendfile() is not really portable, + hence the _LINUX specificness.

This confused somebody who was copying the code for some other use. I have removed all the tests. +PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a + feature that was used to support insecure browsers during the U.S. crypto + embargo. It requires special client support, and Exim is probably the + only MTA that supported it -- and would never use it because real RSA is + always available. This code has been removed, because it had the bad + effect of slowing Exim down by computing (never used) parameters for the + RSA_EXPORT functionality. + +PH/21 On the advice of Timo Sirainen, added a check to the dovecot + authenticator to fail if there's a tab character in the incoming data + (there should never be unless someone is messing about, as it's supposed + to be base64-encoded). Also added, on Timo's advice, the "secured" option + if the connection is using TLS or if the remote IP is the same as the + local IP, and the "valid-client-cert option" if a client certificate has + been verified. + +PH/22 As suggested by Dennis Davis, added a server_condition option to *all* + authenticators. This can be used for authorization after authentication + succeeds. (In the case of plaintext, it servers for both authentication + and authorization.) + +PH/23 Testing for tls_required and lost_connection in a retry rule didn't work + if any retry times were supplied. + +PH/24 Exim crashed if verify=helo was activated during an incoming -bs + connection, where there is no client IP address to check. In this + situation, the verify now always succeeds. + +PH/25 Applied John Jetmore's -Mset patch. + +PH/26 Added -bem to be like -Mset, but loading a message from a file. + +PH/27 In a string expansion for a processed (not raw) header when multiple + headers of the same name were present, leading whitespace was being + removed from all of them, but trailing whitespace was being removed only + from the last one. Now trailing whitespace is removed from each header + before concatenation. Completely empty headers in a concatenation (as + before) are ignored. + +PH/28 Fixed bug in backwards-compatibility feature of PH/09 (thanks to John + Jetmore). It would have mis-read ACL variables from pre-4.61 spool files. + +PH/29 [Removed. This was a change that I later backed out, and forgot to + correct the ChangeLog entry (that I had efficiently created) before + committing the later change.] + +PH/30 Exim was sometimes attempting to deliver messages that had suffered + address errors (4xx response to RCPT) over the same connection as other + messages routed to the same hosts. Such deliveries are always "forced", + so retry times are not inspected. This resulted in far too many retries + for the affected addresses. The effect occurred only when there were more + hosts than the hosts_max_try setting in the smtp transport when it had + the 4xx errors. Those hosts that it had tried were not added to the list + of hosts for which the message was waiting, so if all were tried, there + was no problem. Two fixes have been applied: + + (i) If there are any address or message errors in an SMTP delivery, none + of the hosts (tried or untried) are now added to the list of hosts + for which the message is waiting, so the message should not be a + candidate for sending over the same connection that was used for a + successful delivery of some other message. This seems entirely + reasonable: after all the message is NOT "waiting for some host". + This is so "obvious" that I'm not sure why it wasn't done + previously. Hope I haven't missed anything, but it can't do any + harm, as the worst effect is to miss an optimization. + + (ii) If, despite (i), such a delivery is accidentally attempted, the + routing retry time is respected, so at least it doesn't keep + hammering the server. + +PH/31 Installed Andrew Findlay's patch to close the writing end of the socket + in ${readsocket because some servers need this prod. + +PH/32 Added some extra debug output when updating a wait-xxx database. + Exim version 4.63 -----------------
