Version 4.32 ------------ 1. The exinext utility calls Exim to find out information such as the location of the spool directory. This utility now has -C and -D options, which are passed on to the exim commands. The first specifies an alternate Exim configuration file, and the second sets macros for use within the configuration file. These features are mainly to help in testing, but might also be useful in environment where more than one configuration file is in use. 2. Exim caches the result of checking a named list if it is sure that the list is the same each time. In practice, this means that the cache operates only if the list contains no $ characters, which guarantees that it will not change when it is expanded. Sometimes, however, you may have an expanded list that you know will be the same each time within a given message. For example: domainlist special_domains = ${lookup{$sender_host_address}cdb{/some/file}} This provides a list of domains that depends only on the sending host's IP address. If this domain list is referenced a number of times (for example, in several ACL lines, or in several routers) the result of the check is not cached by default, because Exim does not know that it is going to be the same list each time. By appending "_cache" to "domainlist" you can now tell Exim to go ahead and cache the result anyway. For example: domainlist_cache special_domains = ${lookup{.... If you do this, you should be absolutely sure that caching is going to do the right thing in all cases. When in doubt, leave it out. 3. For compatibility with Sendmail, the command line option -prval:sval is equivalent to -oMr rval -oMs sval and sets the incoming protocol and host name (for trusted callers). The host name and its colon can be omitted when only the protocol is to be set. Note the Exim already has two private options, -pd and -ps, that refer to embedded Perl. It is therefore impossible to set a protocol value of "p" or "s", but I don't think that's a major issue. 4. There is a new expansion operator: ${time_interval:xxxxx} The argument (after sub-expansion) must be a sequence of digits that represents an interval of time as a number of seconds. It is converted into a number of larger units and output in Exim's normal time format, for example, "1w3d4h2m6s". 5. There are two new log selectors that cause additional items to be added to each successful delivery log line: "queue_time" records the amount of time the message has been in the queue on the local host. It is logged as QT=
