Detailed Description

collection of all user filters for access by qsmtpd.c

Function Documentation

enum filter_result cb_nomail	(	const struct userconf *	ds,
		const char **	logmsg,
		enum config_domain *	t
	)

The user does not want to receive any mail

There are three possibilities how to work with the config file "nomail" -if it is empty the mail will simply be rejected with a general error message -if the message starts with "XYY X.Y.Y" (where Y is a decimal number and X is either 4 or 5) this will be used as the error code. -if the message does not start with a SMTP rejection code it will be used with a rejection code of "550 5.7.1 ".

enum filter_result cb_soberg	(	const struct userconf *	ds,
		const char **	logmsg,
		enum config_domain *	t
	)

This checks if the combination of "MAIL FROM:" and "HELO" looks like SoberG

SoberG's MAIL FROM: foo@b.nosp@m.ar.c.nosp@m.om would lead to HELO foo.com

void logwhitelisted	(	const char *	reason,
		const int	t,
		const int	u
	)

write message to syslog that a otherwise rejected mail has been passed because of whitelisting

Parameters

reason	reason of whitelisting
t	which type of filter caused blacklisting
u	which type of filter caused whitelisting
