-DSN Support
---------------------------------------------------------------
-
-DSN Support tries to add RFC 3461 support to Exim. It adds support for
-*) the additional parameters for MAIL FROM and RCPT TO
-*) RFC complient MIME DSN messages for all of
- success, failure and delay notifications
-*) dsn_advertise_hosts main option to select which hosts are able
- to use the extension
-*) dsn_lasthop router switch to end DSN processing
-
-In case of failure reports this means that the last three parts, the message body
-intro, size info and final text, of the defined template are ignored since there is no
-logical place to put them in the MIME message.
-
-All the other changes are made without changing any defaults
-
-Building exim:
---------------
-
-Define
-EXPERIMENTAL_DSN=YES
-in your Local/Makefile.
-
-Configuration:
---------------
-All DSNs are sent in MIME format if you built exim with EXPERIMENTAL_DSN=YES
-No option needed to activate it, and no way to turn it off.
-
-Failure and delay DSNs are triggered as usual except a sender used NOTIFY=...
-to prevent them.
-
-Support for Success DSNs is added and activated by NOTIFY=SUCCESS by clients.
-
-Add
-dsn_advertise_hosts = *
-or a more restrictive host_list to announce DSN in EHLO answers
-Those hosts can then use NOTIFY,ENVID,RET,ORCPT options.
-If a message is relayed to a DSN aware host without changing the envelope
-recipient the options are passed along and no success DSN is generated.
-
-A redirect router will always trigger a success DSN if requested and the DSN
-options are not passed any further.
-
-A success DSN always contains the recipient address as submitted by the
-client as required by RFC. Rewritten addresses are never exposed.
-
-If you used DSN patch up to 1.3 before remove all "dsn_process" switches from
-your routers since you don't need them anymore. There is no way to "gag"
-success DSNs anymore. Announcing DSN means answering as requested.
-
-You can prevent Exim from passing DSN options along to other DSN aware hosts by defining
-dsn_lasthop
-in a router. Exim will then send the success DSN himself if requested as if
-the next hop does not support DSN.
-Adding it to a redirect router makes no difference.

-Certificate name checking
---------------------------------------------------------------
-The X509 certificates used for TLS are supposed be verified
-that they are owned by the expected host. The coding of TLS
-support to date has not made these checks.
+SOCKS
+------------------------------------------------------------
+Support for proxying outbound SMTP via a Socks 5 proxy
+(RFC 1928) is included if Exim is compiled with
+EXPERIMENTAL_SOCKS defined.
-If built with EXPERIMENTAL_CERTNAMES defined, code is
-included to do so for server certificates, and a new smtp transport option
-"tls_verify_cert_hostnames" supported which takes a list of
-names for which the additional checks must be made.
-The option currently defaults to empty, but this may change in
-the future. "*" is probably a suitable value.
-Whether certificate verification is done at all, and the result of
-it failing, is stll under the control of "tls_verify_hosts" nad
-"tls_try_verify_hosts".
+If an smtp transport has a nonempty socks_proxy option
+defined, this is active. The option is expanded and
+should be a list (colon-separated by default) of
+proxy specifiers. Each proxy specifier is a list
+(space-separated by default) where the initial element
+is an IP address and any subsequent elements are options.
-Both Subject and Subject-Alternate-Name certificate fields
-are supported, as are wildcard certificates (limited to
-a single wildcard being the initial component of a 3-or-more
-component FQDN).
+Options are a string <name>=<value>.
+These options are currently defined:
+- "auth", with possible values "none" and "name".
+ Using "name" selects username/password authentication
+ per RFC 1929. Default is "none".
+- "name" sets the authentication username. Default is empty.
+- "pass" sets the authentication password. Default is empty.
+- "port" sets the tcp port number for the proxy. Default is 1080.
+- "tmo" sets a connection timeout in seconds for this proxy. Default is 5.
-The equivalent check on the server for client certificates is not
-implemented. At least one major email provider is using a client
-certificate which fails this check. They do not retry either without
-hte client certificate or in clear.
+Proxies from the list are tried in order until
+one responds. The timeout for the overall connection
+applies to the set of proxied attempts.
-It is possible to duplicate the effect of this checking by
-creative use of Events.
+If events are used, the remote IP/port during a
+tcp:connect event will be that of the proxy.
A TLSA lookup will be done if either of the above options match
and the host-lookup succeded using dnssec.
-If the TLSA lookup succeeds, a TLS connection will be required
-for the host.
+If a TLSA lookup is done and succeeds, a DANE-verified TLS connection
+will be required for the host.
(TODO: specify when fallback happens vs. when the host is not used)
-If dane is in use the following transport options are ignored:
+If DANE is requested and useable (see above) the following transport
+options are ignored:
hosts_require_tls
tls_verify_hosts
tls_try_verify_hosts
tls_crl
tls_verify_cert_hostnames
+If DANE is not usable, whether requested or not, and CA-anchored
+verification evaluation is wanted, the above variables should be set
+appropriately.
+
Currently dnssec_request_domains must be active (need to think about that)
and dnssec_require_domains is ignored.
