This was done some time before quoting was made available + in lsearch files. However, iplsearch files do require colons in IPv6 keys + (notated using the quote facility) so as to distinguish them from IPv4 + keys. This meant that lookups for IP addresses in host lists did not work + for iplsearch lookups. + + This has been fixed by arranging for IPv6 addresses to be expressed with + colons if the lookup type is iplsearch. This is not incompatible, because + previously such lookups could never work. + + The situation is now rather anomolous, since one *can* have colons in + ordinary lsearch keys. However, making the change in all cases is + incompatible and would probably break a number of configurations. + +TK/01 Change PRVS address formatting scheme to reflect latests BATV draft + version. + +MH/01 The "spam" ACL condition code contained a sscanf() call with a %s + conversion specification without a maximum field width, thereby enabling + a rogue spamd server to cause a buffer overflow. While nobody in their + right mind would setup Exim to query an untrusted spamd server, an + attacker that gains access to a server running spamd could potentially + exploit this vulnerability to run arbitrary code as the Exim user. + +TK/02 Bugzilla 502: Apply patch to make the SPF-Received: header use + $primary_hostname instead of what libspf2 thinks the hosts name is. + +MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for + a directory entry by the name of the lookup key. Previously, if a + symlink pointed to a non-existing file or a file in a directory that + Exim lacked permissions to read, a lookup for a key matching that + symlink would fail. Now it is enough that a matching directory entry + exists, symlink or not. (Bugzilla 503.) + +PH/03 The body_linecount and body_zerocount variables are now exported in the + local_scan API. + +PH/04 Added the $dnslist_matched variable. + +PH/05 Unset $tls_cipher and $tls_peerdn before making a connection as a client. + This means they are set thereafter only if the connection becomes + encrypted. + +PH/06 Added the client_condition to authenticators so that some can be skipped + by clients under certain conditions. + +PH/07 The error message for a badly-placed control=no_multiline_responses left + "_responses" off the end of the name. + +PH/08 Added -Mvc to output a copy of a message in RFC 2822 format. + +PH/09 Tidied the code for creating ratelimiting keys, creating them explicitly + (without spaces) instead of just copying the configuration text. + +PH/10 Added the /noupdate option to the ratelimit ACL condition. + +PH/11 Added $max_received_linelength. + + Exim version 4.67 ----------------- @@ -182,6 +249,41 @@ PH/40 When Exim receives a message, it writes the login name, uid, and gid of calls itself on a restart). I have changed the code so that it now always uses the Exim user. +PH/41 (Following a suggestion from Tony Finch) If all the RCPT commands in a + message are rejected with the same error (e.g. no authentication or bad + sender address), and a DATA command is nevertheless sent (as can happen + with PIPELINING or a stupid MUA), the error message that was given to the + RCPT commands is included in the rejection of the DATA command. This is + intended to be helpful for MUAs that show only the final error to their + users. + +PH/42 Another patch from the Sieve maintainer. + +SC/02 Eximstats - Differentiate between permanent and temporary rejects. + Eximstats - Fixed some broken HTML links and added missing column headers + (Jez Hancock). + Eximstats - Fixed Grand Total Summary Domains, Edomains, and Email + columns for Rejects, Temp Rejects, Ham, and Spam rows. + +SC/03 Eximstats - V1.58 Fix to get <> and blackhole to show in edomain tables. + +PH/43 Yet another patch from the Sieve maintainer. + +PH/44 I found a way to check for a TCP/IP connection going away before sending + the response to the final '.' that terminates a message, but only in the + case where the client has not sent further data following the '.' + (unfortunately, this is allowed). However, in many cases there won't be + any further data because there won't be any more messages to send. A call + to select() can be used: if it shows that the input is "ready", there is + either input waiting, or the socket has been closed. An attempt to read + the next input character can distinguish the two cases. Previously, Exim + would have sent an OK response which the client would never have see. + This could lead to message repetition. This fix should cure that, at + least in a lot of common cases. + +PH/45 Do not advertise STARTTLS in response to HELP unless it would be + advertised in response to EHLO. + Exim version 4.66 -----------------
