EXIM 4 WISH LIST
----------------
address?
------------------------------------------------------------------------------
-(172) 11-Sep-2000 S Allow file/directory in appendfile to override
-"Michael J. Tubby"
-
-When appendfile is called from forward or filter files, it ignores file or
-directory settings. Maybe they should override. The path set by the forward or
-filter is available in $address_file these days, so it could be used to create
-a longer path.
-------------------------------------------------------------------------------
-
(173) 18-Sep-2000 S A way of doing lsearches with EOL terminated keys
Jason Robertson
exim_dbmbuild to make them into DBM files.
------------------------------------------------------------------------------
-(174) 19-Sep-2000 S A way of using a different port for fallback hosts.
-Dean Brooks
-------------------------------------------------------------------------------
-
(181) 10-Nov-2000 S Compile-time options for ignoring Sendmail options
So that new ones could be accommodated easily.
headers_remove = "X-*:Additional-header"
------------------------------------------------------------------------------
-(188) 02-Jan-2001 S Make pipe timeout a temporary error
-Georg v.Zezschwitz
-
-A way to make a timeout into a temporary error.
-------------------------------------------------------------------------------
-
(190) 03-Jan-2001 M Multiple message operations in eximon
------------------------------------------------------------------------------
might have. At ACL time, one would need to verify the recipient, and determine
that it routed to host X.
-. A new lookup library that operates on a specially prepared file of IP
-addresses and masks so that a single "lookup" yields a yes/no answer. This
-should be a freestanding thing - needs a utility to build the file from a list.
-
. People want to change the wording of messages; can we find an efficient way
of allowing this? (Maybe put all messages into a separate module?) The problem
is not in the messages themselves, but in the values that get inserted into
. Implement randomize for ldap/sql servers.
. Add an option for ETRN that says "wait for the command to finish, and use its
-stdout as the SMTP response."
+stdout as the SMTP response." // A serialized ETRN now does the waiting, but
+there is as yet no way to use the status. //
. -odsomething for "ignore retry when doing immediate delivery".
it were 4xx. Or possible add a sophisticated "after command X, treat xxx as
yyy".
-. A way of rewriting addresses in non-standard header lines such as
-Mail-Followup-To.
-
. Global option to enable initgroups() for exim uid. Default off.
. When verifying a sender, should it be rewritten with any T rewrites, because
. Options and/or a utility to enable non-privileged users to view the queue
(e.g. -bpp), manipulate their own messages, etc.
-. Specify a port along with a host in a route_list.
-
. A generalized "From" escaping scheme that also escapes >From so that the
whole thing can be reversed.
John W Baxter
May be tricky, because at the higher levels, the format of the query is not
-understood.
-------------------------------------------------------------------------------
-
-(8) 01-Jan-02 S Expand once_repeat in autoreply
-John Jetmore
+understood. // There is now a fudge that works in some cases. See ChangeLog
+4.51/PH/10. //
------------------------------------------------------------------------------
(9) 01-Jan-02 S Headers as well as body in file for autoreply
copies to the same address.
------------------------------------------------------------------------------
-(73) 17-Jul-02 M Match a list from within a condition
-
-e.g. ${if matchdomain {$domain}{+domainlist} ...
- ${if matchhost {$sender_host_address}{1.2.3.4/10:2.3.4.5/16}...
-
-Thought needed about how to handle host names. This may be too messy to specify
-cleanly.
-
-22-Apr-04: Implemented for domains, addresses, and local parts. Hosts are
-too messy!
-
-The only sensible approach seems to be to allow IP address arguments only.
-Anything else should be diagnosed as an error. However, if a name appears in
-the list, a PTR lookup should be done. This may require a lot of refactoring
-in the code, because of the current assumption that were are (almost) always
-dealing with THE sending host.
-------------------------------------------------------------------------------
-
(74) 22-Jul-02 M Extend -bV to do more semantic checking
For example, diagnose "local_hosts" that should probably be "+local_hosts".
Suggested patch supplied.
------------------------------------------------------------------------------
-(171) 23-Jun-03 S Option to make timeout a soft failure on pipe transport
-
-------------------------------------------------------------------------------
-
(172) 23-Jun-03 M Option to make SQL query to specific server
------------------------------------------------------------------------------
different kinds of verify failure.
------------------------------------------------------------------------------
-(196) 30-Sep-03 S A way of detecting whether it was HELO or EHLO in the ACL
-
-$received_protocol isn't reset until after the command is accepted (which
-seems right), and $smtp_data shows only the arguments. Maybe $smtp_command?
-------------------------------------------------------------------------------
-
(197) 30-Sep-03 S MACROS_DROP_PRIVS and ALT_CONFIG_DROP_PRIVS
Now that alternative configurations can be restricted to certain directories,
Unfortunately, this isn't quite as trivial as it seems.
------------------------------------------------------------------------------
-(215) 14-Nov-03 S A way of turning off message-submission fix-ups
-
-Globally, and perhaps also via an ACL control so that it can be done on a
-per-message basis. Is this still needed? Since this item was added to this
-list, default fixups for non-local messages have been removed, and control =
-submission has been added.
-------------------------------------------------------------------------------
-
(215) 26-Nov-03 M/L Conversion of IDNA domain names for logging
IDNA (RFCs 3490-3492) converts domains names containing non-ASCII characters
supported, but not individual messages; no doubt one day this will be wanted.
------------------------------------------------------------------------------
-(335) 14-Jun-05 T Re-arrange default configuration
-
-A small niggle which might be worth fixing is the ordering of the ACL in the
-default configuration file. The relay_from_hosts and authenticated clauses
-would be better off before the dnslists examples. However, this should be left
-until a x.x0 release, because of the documentation implications.
-------------------------------------------------------------------------------
-
(336) 16-Jun-05 M Show recipient(s) after header check failure
The mainlog line for "There is no valid sender in any header line" shows the
data in the reject log does show the envelope recipients as part of its
additional data.
------------------------------------------------------------------------------
---- HWM 336 ------------------------------------------------------------------
+
+(337) 29-Jun-05 S Add "defer" to $recipient_verify_failure
+
+This is for when defer_ok was set when verifying recipients. Since this isn't
+for a failure, we probably also need "ok" for the non-fail case.
+------------------------------------------------------------------------------
+
+(338) 14-Jul-05 M Change to Bind 9 API
+
+Exim uses the original API for calling the DNS resolver. There is a newer API
+available, and noises are being made in some OS that compatibility with the old
+API is going to be dropped. Nevertheless, there are sure to be systems about
+for ages that require the use of the old API. Therefore, we will have to
+implement not only an interface to the new API, but a backwards compatibility
+feature. It would be nice if this was automatic.
+------------------------------------------------------------------------------
+
+(339) 28-Jul-05 S Log name of maildir file
+
+This wish is for an option to log the name of the file that is written in
+maildir format (e.g. time.pid.host).
+------------------------------------------------------------------------------
+
+(340) 30-Aug-05 M Match more than one item
+
+match_address, for instance, matches one address to a list. The wish is to be
+able to supply two lists; for each address in the first list, search the
+second. Maybe something like ${match_any{...}{...}} is needed.
+------------------------------------------------------------------------------
+
+(341) 15-Sep-05 S Add /return_path_retain to submission mode
+
+This would re-instate the behaviour prior to change 4.52/PH/04.
+------------------------------------------------------------------------------
+
+(342) 26-Sep-05 T Log and maybe defer odd values for condition pre-condition
+
+Odd values for "condition" in an ACL cause it to defer. In a router, they are
+treated as "true". At least they should be logged in a router, and perhaps they
+should also defer, for compatibility with ACLs.
+------------------------------------------------------------------------------
+
+(343) 03-Oct-05 M A query-style lookup for scanning flat files
+
+The natural syntax for this would be to use a regex, like this:
+${lookup regex{/some/file regex}{found-string}{not-found-string}}
+However, it would be natural to want to use $1 etc in the found-string; this
+would be hard because of the lookup caching (if repeated, the lookup won't
+actually be done and therefore the numerical variables won't be set), and in
+any case, even without caching (and it could, I suppose, be disabled for this
+lookup) those variables are not in the right storage pool even if they were
+preserved after the lookup.
+
+An alternative approach might be to implement something like this:
+
+ ${scanfile{/some/file}{sub-expression}}
+
+where the sub-expression is expanded for every line in the file, with each line
+in turn being put into $value. This is like a conditional ${readfile, and in
+fact ${readfile could be written using ${scanfile. It would be nice to find a
+way of stopping the scan once something has happened. The only thing I can
+think of is to invent a variable that changes when scanning a line generates
+some non-null text, and then always to stop on a forced failure. That would
+allow expressions like this:
+
+ ${scanfile{/some/file}
+ {
+ ${if eq{$generated}{}{${if match{regex}{$value}{something}}} fail}
+ }}
+
+It's all rather clumsy. Once a line has matched and generated some text, the
+next iteration would stop the scan. Another thought: maybe use $scanline
+instead of $value (to save confusion) and have $scantext containing everything
+that's been generated so far. That sounds pretty flexible.
+------------------------------------------------------------------------------
+
+(344) 10-Oct-05 M Make debug_print work in authenticators
+------------------------------------------------------------------------------
+
+(345) 14-Oct-05 M Standardize rejection messages
+
+"The parsing for rejection lines is a bit of a mess, and fairly
+unmaintainable. Do you think it would be possible to standardise
+rejection/refusal log messages? How about something like:
+
+(<ID>|16 Spaces) *< (Connection|MAIL|RCPT|HELO|EHLO|DATA) rejected (from
+<Address>)?: <Reason> (\(<Detail>\))?"
+------------------------------------------------------------------------------
+
+(346) 20-Oct-05 S Set $domain and $local_part in retry matching
+
+Currently, these variables are unset. Make it like rewrite matching.
+------------------------------------------------------------------------------
+
+(347) 15-Nov-05 M Arrange to expand data from wildlsearch
+
+This would allow keys that are regular expressions to set up numerical
+variables that are included in the data. This has to be done inside the lookup
+code, because of caching. Probably means we have to invent ewildlsearch and
+enwildlsearch.
+------------------------------------------------------------------------------
+
+(350) 28-Feb-06 S Additional errors for retry rules
+
+(i) Unexpected connection close; (ii) mail_4xx.
