Furthermore, because there are apparently + some really broken clients that do this, Exim will even accept AUTH after + HELO when this control is set. It should only be used if you really need + it, and you should limit its use to those broken hosts that do not work + without it. For example: + + warn hosts = 192.168.34.25 + control = allow_auth_unadvertised + + This control is permitted only in the connection and HELO ACLs. + +PH/18 There is a new ACL modifier called "add_header" which does what its name + implies. It specifies one of more header lines that are to be added to an + incoming message, assuming, of course, that the message is ultimately + accepted. + + This modifier is permitted in the MAIL, RCPT, PREDATA, DATA, MIME, and + non-SMTP ACLs (in other words, those that are concerned with accepting a + message). Added header lines are accumulated during the MAIL, RCPT, and + PREDATA ACLs, with any duplicates being discarded. They are then added to + the message before processing the DATA and MIME ACLs, during which + further added header lines are accumulated, again with duplicates + discarded. Thus, it is possible to add two identical header lines to an + SMTP message, but only if one is added before DATA and one after. + + In the case of non-SMTP messages, new headers are accumulated during the + non-SMTP ACL, and added to the message at the end. + + The add_header modifier is available for use with all ACL verbs. In the + case of the WARN verb, add_header supersedes the use of "message" for + this purpose; for the other verbs, it provides a new facility. If both + add_header and "message" are present on a WARN verb, both are processed + according to their specifications. + + The add_header modifier acts immediately it is encountered during the + processing of an ACL. This is different to the (now-deprecated) use of + "message" on a WARN verb, where the action is taken only if all the + conditions are true. Notice the difference between these two cases on a + RCPT ACL: + + deny add_header = ADDED: some text + + + deny + add_header = ADDED: some text + + In the first case, the header is always added, whether or not the current + recipient is rejected. In the second case, the header is added only if + the recipient is rejected. + + If add_header appears more than once on an ACL statement, multiple + headers are added, provided that they have different content. (In the + case of WARN with "message", only the last value of "message" is used.) + + The facility for specifying where the new header is to be inserted, as + described for WARN with "message" in section 39.19 of the 4.60 manual, is + supported. + +PH/19 The following errors can now be detected in retry rules: + + mail_4xx This is like rcpt_4xx, but applies to MAIL commands + + data_4xx This is like rcpt_4xx, but applies to DATA commands and the + response code after the end of the data + + lost_connection This error occurs when the server unexpectedly closes + the SMTP connection. There may, of course, legitmate reasons + for this (host died, network died), but if it repeats a lot + for the same host, it indicates something odd. + + tls_required The server was required to use TLS (hosts_require_tls), + but either did not offer it, or responded with 4xx to + STARTTLS, or there was a problem setting up the TLS connection + + Note that a 5xx response to STARTTLS is a permanent error. + +PH/20 There are now two options for the exicyclog script: + + -k specifies the number of old logs to keep, overriding the + default that is set when Exim is built. + + -l specifies the log file path, in the same format as the + log_file_path option (e.g. /var/log/exim_%slog), again, + overriding the script's default - which is to find the setting + from Exim's configuration. + Version 4.60 ------------
