The expansion-test faciility (exim -be) can set variables. + + 2. An event on a failing SMTP AUTH, for both client and server operations. + + 3.

The smtp transport option "max_rcpt" is now expanded before use. + +Version 4.96 +------------ + + 1. A new ACL condition: seen. Records/tests a timestamp against a key. + + 2. A variant of the "mask" expansion operator to give normalised IPv6. + + 3. UTC output option for exim_dumpdb, exim_fixdb. + + 4. An event for failing TLS connects to the daemon. + + 5. The ACL "debug" control gains options "stop", "pretrigger" and "trigger". + + 6. Query-style lookups are now checked for quoting, if the query string is + built using untrusted data ("tainted"). For now lack of quoting is merely + logged; a future release will upgrade this to an error. + + 7. The expansion conditions match_ and inlist now set $value for + the expansion of the "true" result of the ${if}. With a static list, this + can be used for de-tainting. + + 8. Recipient verify callouts now set $domain_data & $local_part_data, with + de-tainted values. + +Version 4.95 +------------ + + 1. The fast-ramp two phase queue run support, previously experimental, is + now supported by default. + + 2. The native SRS support, previously experimental, is now supported. It is + not built unless specified in the Local/Makefile. + + 3. TLS resumption support, previously experimental, is now supported and + included in default builds. + + 4. Single-key LMDB lookups, previously experimental, are now supported. + The support is not built unless specified in the Local/Makefile. + + 5. Option "message_linelength_limit" on the smtp transport to enforce (by + default) the RFC 998 character limit. + + 6. An option to ignore the cache on a lookup. + + 7. Quota checking during reception (i.e. at SMTP time) for appendfile- + transport-managed quotas. + + 8. Sqlite lookups accept a "file=" option to specify a per-operation + db file, replacing the previous prefix to the SQL string (which had + issues when the SQL used tainted values). + + 9. Lsearch lookups accept a "ret=full" option, to return both the portion + of the line matching the key, and the remainder. + +10. A command-line option to have a daemon not create a notifier socket. + +11. Faster TLS startup. When various configuration options contain no + expandable elements, the information can be preloaded and cached rather + than the previous behaviour of always loading at startup time for every + connection. This helps particularly for the CA bundle. + +12. Proxy Protocol Timeout is configurable via "proxy_protocol_timeout" + main config option. + +13. Option "smtp_accept_max_per_connection" is now expanded. + +14. Log selector "queue_time_exclusive", enabled by default, to exclude the + time taken for reception from QT log elements. + +15. Main option "smtp_backlog_monitor", to set a level above which listen + socket backlogs are logged. + +16. Main option "hosts_require_helo", requiring HELO or EHLO before MAIL. + +17. A main config option "allow_insecure_tainted_data" allows to turn + +18. TLS ALPN handling. By default, refuse TLS connections that try to specify + a non-smtp (eg. http) use. Options for customising. + +19. Support for MacOS (darwin) has been dropped. + + +Version 4.94 +------------ 1. EXPERIMENTAL_SRS_NATIVE optional build feature. See the experimental.spec file. - 2.

Server-side support in the gsasl authenticator for encrypted passwords, as + an alternate for the existing plaintext. + + 6. Variable $local_part_data now also set by router check_local_user option, + with an de-tainted version of $local_part. + + 7. Named-list definitions can now be prefixed "hide" so that "-bP" commands do + not output the content. Previously this could only be done on options. + + 8. As an experimental feature, the dovecot authentication driver supports inet + sockets. Previously it was unix-domain sockets only. + + 9. The ACL control "queue_only" can also be spelled "queue", and now takes an + option "first_pass_route" to do the same as a "-odqs" on the command line. + +10. Items specified for the router and transport headers_remove option can use + a trailing asterisk to specify globbing. + +11. New $queue_size variable. + +12. New variables $local_part_{pre,suf}fix_v. + +13. New main option "sqlite_dbfile", for use in preference to prefixing the + lookup string. The older method fails when tainted variables are used + in the lookup, as the filename becomes tainted. The new method keeps the + filename separate. + +14. Options on the dsearch lookup, to return the full path and to filter + filetypes for matching. + +15. Options on pgsql and mysql lookups, to specify server separate from the + lookup string. + +16. An option on all single-key lookups, to return (on a hit) a de-tainted + version of the lookup key rather than the looked-up data. + +17. $domain_data and $local_part_data are now set by all list-match successes. + Previously only list items that performed lookups did so. + Also, matching list items that are tail-match or RE-match now set the + numeric variables $0 (etc) in the same way os other RE matches. + +18. Expansion item ${listquote {}}. + +19. An option for the ${readsocket {}{}{}} expansion to make the result data + cacheable. + +20. dkim_verify_min_keysizes, a list of minimum acceptable public-key sizes. + +21. bounce_message_file and warn_message_file are now expanded before use. + +22.
