Detailed Description

functions for handling of control/smtproutes

Function Documentation

static int hascolon ( const char *  s )

static

check smtproutes entries for basic syntax errors

Returns

0 if the line is valid, i.e. it contains exactly 1 or 2 colons

static int parse_route_params ( struct ips **  mx, const char *  remhost, unsigned int *  targetport, void *  buf, const char *  host, const char *  port  )

static

parse the parts of an smtproute

Parameters

mx	MX result list is stored here
remhost	original remote host
targetport	targetport will be stored here
buf	additional buffer, will be freed in case of fatal error
host	host name of smtproute or NULL
port	port string of smtproute of NULL

Return values

0	values were successfully parsed
<0	error code during setup

The function will abort the program if a parse error occurs.

struct ips* smtproute	(	const char *	remhost,
		const size_t	reml,
		unsigned int *	targetport
	)

get static route for domain

Parameters

remhost	target to look up
reml	strlen(remhost)
targetport	port on the remote host to connect to

Returns

MX list if route present

Return values

NULL	a runtime error occurred while reading the control file, errno is set

If control/smtproutes contains a syntax error the program is terminated. On runtime error (out of memory) NULL is returned and errno is set.

static int validroute ( const char *  s )

static

callback for loadlistfd() to check validity of smtprouts.d file contents

Parameters

s	the line to check

This not only checks the current line, but also sets tagmask to detect duplicate lines.
