EXIM 4 WISH LIST
----------------
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.
. 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.
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
This wish is for an option to log the name of the file that is written in
maildir format (e.g. time.pid.host).
------------------------------------------------------------------------------
---- HWM 339 ------------------------------------------------------------------
+
+(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.
