If IP literals are enabled, the ipliteral router declines to handle IPv6 literal addresses. +PH/02 There are now 20 of each type of ACL variable by default (instead of 10). + It is also possible to change the numbers by setting ACL_CVARS and/or + ACL_MVARS in Local/Makefile. Backward compatibility is maintained if you + upgrade to this release with existing messages containing ACL variable + settings on the queue. However, going in the other direction + (downgrading) will not be compatible; the values of ACL variables will be + lost. + +PH/03 If quota_warn_message contains a From: header, Exim now refrains from + adding the default one. Similarly, if it contains a Reply-To: header, the + errors_reply_to option, if set, is not used. + +PH/04 The variables $auth1, $auth2, $auth3 are now available in authenticators, + containing the same values as $1, $2, $3. The new variables are provided + because the numerical variables can be reset during string expansions + (for example, during a "match" operation) and so may lose the + authentication data. The preferred variables are now the new ones, with + the use of the numerical ones being deprecated, though the support will + not be removed, at least, not for a long time. + +PH/05 The "control=freeze" ACL modifier can now be followed by /no_tell. If + the global option freeze_tell is set, it is ignored for the current + message (that is, nobody is told about the freezing), provided all the + "control=freeze" modifiers that are obeyed in the current message have + the /no_tell option. + +PH/06 In both GnuTLS and OpenSSL, an expansion of tls_privatekey that results + in an empty string is now treated as unset. + +PH/07 There is a new log selector called sender_verify_fail, which is set by + default. If it is unset, the separate log line that gives details of a + sender verification failure is not written. Log lines for the rejection + of SMTP commands (e.g. RCPT) contain just "sender verify failed", so some + detail is lost. + +PH/08 The default for dns_check_names_pattern now allows slashes within names, + as there are now some PTR records that contain slashes. This check is + only to protect against broken name servers that fall over on strange + characters, so the fact that it applies to all lookups doesn't matter. + +PH/09 The default for rfc4131_query_timeout has been changed from 30s to 5s. + +PH/10 When compiled on FreeBSD, NetBSD, or BSD/OS, the pipe transport has a new + Boolean option called use_classresources, defaulting false. If it is set + true, the setclassresources() function is used to set resource limits + when a pipe transport is run to perform a delivery. The limits for the + uid under which the pipe is to run are obtained from the login class + database. + +PH/11 If retry_interval_max is set greater than 24 hours, it is quietly reset + to 24 hours. This avoids potential overflow problems when processing G + and H retry rules, and it seems reasonable to require a retry at least + once a day. + +PH/12 When the plaintext authenticator is running as a client, the server + challenges are now checked to ensure they are valid base64 strings. The + default action on failure is to abort the authentication. However, if + client_ignore_invalid_base64 is set true, invalid responses are ignored. + +PH/13 When the plaintext authenticator is running as a client, the challenges + from the server are placed in $auth1, $auth2, etc. as they are received. + Thus, the challege that is received in response to sending the first + string (with the AUTH command) can be used in the expansion of the second + string, and so on. Currently, up to 3 challenge strings are available in + this way. If an invalid base64 string is received when client_ignore_ + invalid_base64 is set, an empty string is put in the $auth variable. + +PH/14 Messages created by the autoreply transport now contain a References: + header. This is constructed in accordance with rules that are described + in section 3.64 of RFC 2822, which states that replies should contain + such a header line, and section 3.14 of RFC 3834, which states that + automatic responses are not different in this respect. However, because + some mail processing software does not cope well with very long header + lines, no more than 12 message IDs are copied from the References: header + line in the incoming message. If there are more than 12, the first one + and then the final 11 are copied, before adding the message ID of the + incoming message. + Version 4.60 ------------
