Detailed Description

definitions for common parts from Qsmtpd exported from qsmtpd.c

Function Documentation

void conn_cleanup

(

const int

rc

)

clean up the allocated data and exit the process

Parameters

rc	desired return code of the process

int err_control

(

const char *

fn

)

write and log error message if opening config file leads to an error

Parameters

fn	name of the file that caused the error

See also

err_control2

int err_control2	(	const char *	msg,
		const char *	fn
	)

write and log error message if opening config file leads to an error

Parameters

msg	additional message to log
fn	name of the file that caused the error

See also

err_control

pid_t fork_clean

(

)

fork() but clean up internal structures

This will work exactly like fork(). If it returns 0 (i.e. you are the child) it will also clean the memory mappings etc. of the Qsmtpd process that the child doesn't need.

int pipe_move	(	int	p[2],
		int	target
	)

move the read end of the pipe to the target descriptor

Parameters

p	both ends of the pipe
target	the target descriptor of the read end

Returns

if everything went smooth

Return values

0	everything is fine

This will move the read end of the pipe to target, closing both the write end of the pipe and the old read end of the pipe. This is intended to be called in the child process directly after forking, but before execve().

Variable Documentation

int authhide

hide source of authenticated mail

int badbounce

bounce message with more than one recipient

unsigned long comstate

status of the command state machine

status of the command state machine, initialized to noop

struct smtpcomm* current_command

the SMTP command currently processed

unsigned long databytes

maximum message size

unsigned int goodrcpt

number of valid recipients

string heloname

the fqdn to show in helo

string liphost

replacement domain if to address is <foo@[ip]>

replacement domain if TO address is <foo@[ip]>

string msgidhost

the fqdn to use if a message-id is added

int relayclient

flag if this client is allowed to relay by IP: 0 unchecked, 1 allowed, 2 denied

unsigned long sslauth

if SMTP AUTH is only allowed after STARTTLS

int submission_mode

if we should act as message submission agent

struct xmitstat xmitstat

This contains some flags describing the transmission and it's status.
