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. + +Proxies from the list are tried in order 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. + + + + DANE ------------------------------------------------------------ DNS-based Authentication of Named Entities, as applied diff --git a/src/scripts/MakeLinks b/src/scripts/MakeLinks index a50f75b36..f68fd6f4b 100755 --- a/src/scripts/MakeLinks +++ b/src/scripts/MakeLinks @@ -105,6 +105,7 @@ ln -s ../../src/transports/pipe.h pipe.h ln -s ../../src/transports/pipe.c pipe.c ln -s ../../src/transports/smtp.h smtp.h ln -s ../../src/transports/smtp.c smtp.c +ln -s ../../src/transports/smtp_socks.c smtp_socks.c ln -s ../../src/transports/tf_maildir.c tf_maildir.c ln -s ../../src/transports/tf_maildir.h tf_maildir.h diff --git a/src/src/EDITME b/src/src/EDITME index 353dde3ee..d48f268b9 100644 --- a/src/src/EDITME +++ b/src/src/EDITME @@ -494,6 +494,9 @@ EXIM_MONITOR=eximon.bin # Uncomment the following line to add DANE support # EXPERIMENTAL_DANE=yes +# Uncomment the following line to add SOCKS support +# EXPERIMENTAL_SOCKS=yes + ############################################################################### # THESE ARE THINGS YOU MIGHT WANT TO SPECIFY # ############################################################################### diff --git a/src/src/config.h.defaults b/src/src/config.h.defaults index e339bdf9e..ac4994a3e 100644 --- a/src/src/config.h.defaults +++ b/src/src/config.h.defaults @@ -170,11 +170,12 @@ it's a default value. */ #define EXPERIMENTAL_DANE #define EXPERIMENTAL_DCC #define EXPERIMENTAL_DMARC +#define EXPERIMENTAL_EVENT #define EXPERIMENTAL_PROXY #define EXPERIMENTAL_REDIS +#define EXPERIMENTAL_SOCKS #define EXPERIMENTAL_SPF #define EXPERIMENTAL_SRS -#define EXPERIMENTAL_EVENT /* For developers */ #define WANT_DEEPER_PRINTF_CHECKS diff --git a/src/src/exim.c b/src/src/exim.c index c94bdc1db..54725ef37 100644 --- a/src/src/exim.c +++ b/src/src/exim.c @@ -853,6 +853,9 @@ fprintf(f, "Support for:"); #ifdef EXPERIMENTAL_REDIS fprintf(f, " Experimental_Redis"); #endif +#ifdef EXPERIMENTAL_SOCKS + fprintf(f, " Experimental_SOCKS"); +#endif fprintf(f, "\n"); fprintf(f, "Lookups (built-in):"); diff --git a/src/src/functions.h b/src/src/functions.h index 49bb5a952..df40d6456 100644 --- a/src/src/functions.h +++ b/src/src/functions.h @@ -208,6 +208,7 @@ extern uschar *host_ntoa(int, const void *, uschar *, int *); extern int host_scan_for_local_hosts(host_item *, host_item **, BOOL *); extern void invert_address(uschar *, uschar *); +extern int ip_addr(void *, int, const uschar *, int); extern int ip_bind(int, int, uschar *, int); extern int ip_connect(int, int, const uschar *, int, int); extern int ip_connectedsocket(int, const uschar *, int, int, @@ -358,11 +359,10 @@ extern int sieve_interpret(uschar *, int, uschar *, uschar *, uschar *, extern void sigalrm_handler(int); extern BOOL smtp_buffered(void); extern void smtp_closedown(uschar *); -extern int smtp_connect(host_item *, int, int, uschar *, int, BOOL, const uschar * -#ifdef EXPERIMENTAL_EVENT - , uschar * -#endif - ); +extern int smtp_connect(host_item *, int, int, uschar *, int, + transport_instance *); +extern int smtp_sock_connect(host_item *, int, int, uschar *, + transport_instance * tb, int); extern int smtp_feof(void); extern int smtp_ferror(void); extern uschar *smtp_get_connection_info(void); diff --git a/src/src/ip.c b/src/src/ip.c index f6072c2e8..83c8d167b 100644 --- a/src/src/ip.c +++ b/src/src/ip.c @@ -97,24 +97,11 @@ ip_addrinfo(const uschar *address, struct sockaddr_in6 *saddr) * Bind socket to interface and port * *************************************************/ -/* This function binds a socket to a local interface address and port.
