+Transport post-delivery actions
+--------------------------------------------------------------
+
+An arbitrary per-transport string can be expanded on successful delivery,
+and (for SMTP transports) a second string on deferrals caused by a host error.
+This feature may be used, for example, to write exim internal log information
+(not available otherwise) into a database.
+
+In order to use the feature, you must set
+
+EXPERIMENTAL_TPDA=yes
+
+in your Local/Makefile
+
+and define the expandable strings in the runtime config file, to
+be executed at end of delivery.
+
+Additionally, there are 6 more variables, available at end of
+delivery:
+
+tpda_delivery_ip IP of host, which has accepted delivery
+tpda_delivery_port Port of remote host which has accepted delivery
+tpda_delivery_fqdn FQDN of host, which has accepted delivery
+tpda_delivery_local_part local part of address being delivered
+tpda_delivery_domain domain part of address being delivered
+tpda_delivery_confirmation SMTP confirmation message
+
+In case of a deferral caused by a host-error:
+tpda_defer_errno Error number
+tpda_defer_errstr Error string possibly containing more details
+
+The $router_name and $transport_name variables are also usable.
+
+
+To take action after successful deliveries, set the following option
+on any transport of interest.
+
+tpda_delivery_action
+
+An example might look like:
+
+tpda_delivery_action = \
+${lookup pgsql {SELECT * FROM record_Delivery( \
+ '${quote_pgsql:$sender_address_domain}',\
+ '${quote_pgsql:${lc:$sender_address_local_part}}', \
+ '${quote_pgsql:$tpda_delivery_domain}', \
+ '${quote_pgsql:${lc:$tpda_delivery_local_part}}', \
+ '${quote_pgsql:$tpda_delivery_ip}', \
+ '${quote_pgsql:${lc:$tpda_delivery_fqdn}}', \
+ '${quote_pgsql:$message_exim_id}')}}
+
+The string is expanded after the delivery completes and any
+side-effects will happen. The result is then discarded.
+Note that for complex operations an ACL expansion can be used.
+
+
+In order to log host deferrals, add the following option to an SMTP
+transport:
+
+tpda_host_defer_action
+
+This is a private option of the SMTP transport. It is intended to
+log failures of remote hosts. It is executed only when exim has
+attempted to deliver a message to a remote host and failed due to
+an error which doesn't seem to be related to the individual
+message, sender, or recipient address.
+See section 47.2 of the exim documentation for more details on how
+this is determined.
+
+Example:
+
+tpda_host_defer_action = \
+${lookup mysql {insert into delivlog set \
+ msgid = '${quote_mysql:$message_exim_id}', \
+ senderlp = '${quote_mysql:${lc:$sender_address_local_part}}', \
+ senderdom = '${quote_mysql:$sender_address_domain}', \
+ delivlp = '${quote_mysql:${lc:$tpda_delivery_local_part}}', \
+ delivdom = '${quote_mysql:$tpda_delivery_domain}', \
+ delivip = '${quote_mysql:$tpda_delivery_ip}', \
+ delivport = '${quote_mysql:$tpda_delivery_port}', \
+ delivfqdn = '${quote_mysql:$tpda_delivery_fqdn}', \
+ deliverrno = '${quote_mysql:$tpda_defer_errno}', \
+ deliverrstr = '${quote_mysql:$tpda_defer_errstr}' \
+ }}

+Redis Lookup
+--------------------------------------------------------------
+
+Redis is open source advanced key-value data store. This document
+does not explain the fundamentals, you should read and understand how
+it works by visiting the website at http://www.redis.io/.
+
+Redis lookup support is added via the hiredis library. Visit:
+
+ https://github.com/redis/hiredis
+
+to obtain a copy, or find it in your operating systems package repository.
+If building from source, this description assumes that headers will be in
+/usr/local/include, and that the libraries are in /usr/local/lib.
+
+1. In order to build exim with Redis lookup support add
+
+EXPERIMENTAL_REDIS=yes
+
+to your Local/Makefile. (Re-)build/install exim. exim -d should show
+Experimental_Redis in the line "Support for:".
+
+EXPERIMENTAL_REDIS=yes
+LDFLAGS += -lhiredis
+# CFLAGS += -I/usr/local/include
+# LDFLAGS += -L/usr/local/lib
+
+The first line sets the feature to include the correct code, and
+the second line says to link the hiredis libraries into the
+exim binary. The commented out lines should be uncommented if you
+built hiredis from source and installed in the default location.
+Adjust the paths if you installed them elsewhere, but you do not
+need to uncomment them if an rpm (or you) installed them in the
+package controlled locations (/usr/include and /usr/lib).
+
+
+2. Use the following global settings to configure Redis lookup support:
+
+Required:
+redis_servers This option provides a list of Redis servers
+ and associated connection data, to be used in
+ conjunction with redis lookups. The option is
+ only available if Exim is configured with Redis
+ support.
+
+For example:
+
+redis_servers = 127.0.0.1/10/ - using database 10 with no password
+redis_servers = 127.0.0.1//password - to make use of the default database of 0 with a password
+redis_servers = 127.0.0.1// - for default database of 0 with no password
+
+3. Once you have the Redis servers defined you can then make use of the
+experimental Redis lookup by specifying ${lookup redis{}} in a lookup query.
+
+4. Example usage:
+
+(Host List)
+hostlist relay_from_ips = <\n ${lookup redis{SMEMBERS relay_from_ips}}
+
+Where relay_from_ips is a Redis set which contains entries such as "192.168.0.0/24" "10.0.0.0/8" and so on.
+The result set is returned as
+192.168.0.0/24
+10.0.0.0/8
+..
+.
+
+(Domain list)
+domainlist virtual_domains = ${lookup redis {HGET $domain domain}}
+
+Where $domain is a hash which includes the key 'domain' and the value '$domain'.
+
+(Adding or updating an existing key)
+set acl_c_spammer = ${if eq{${lookup redis{SPAMMER_SET}}}{OK}}
+
+Where SPAMMER_SET is a macro and it is defined as
+
+"SET SPAMMER <some_value>"
+
+(Getting a value from Redis)
+
+set acl_c_spam_host = ${lookup redis{GET...}}
+
