-Support for proxying outbound SMTP via a Socks 5 proxy
-(RFC 1928) is included if Exim is compiled with
-EXPERIMENTAL_SOCKS defined.
-
-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.
-
-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.
-- "pri" specifies a priority for the server within the list, higher
- values being tried first. The default priority is 1.
-- "weight" specifies a selection bias. Within a priority set servers
- are queried in a random fashion, weighted by this value. The default
- value for selection bias is 1.
-
-Proxies from the list are tried according to their priority
-and weight settings until one responds. The timeout for the
-overall connection applies to the set of proxied attempts.
-
-If events are used, the remote IP/port during a
-tcp:connect event will be that of the proxy.
