Detailed Description

validate email addresses

Function Documentation

int addrparse	(	char *	in,
		const int	flags,
		string *	addr,
		char **	more,
		struct userconf *	ds,
		const char *	rcpthosts,
		const off_t	rcpthsize
	)

check an email address for syntax errors and/or existence

Parameters

in	input to parse
flags	0: mail from checks 1: rcpt to checks (e.g. source route is allowed)
addr	struct string to contain the address (memory will be malloced, is set if 0 or -1 is returned)
more	here starts the data behind the first '>' behind the first '<' (or NULL if line ends after the '>')
ds	store the userconf of the user here
rcpthosts	array of the valid rcpthosts
rcpthsize	size of rcpthosts array

Returns

if address was validated

Return values

0	address exists locally
>0	on error (e.g. ENOMEM, return code is error code)
-2	if address not local (this is of course no error condition for MAIL FROM)
-1	if address local but nonexistent (expired or most probably faked) OR if domain of address does not exist (in both cases error is sent to network before leaving)

ds may be NULL in case the result is not interesting (e.g. if only checking MAIL FROM).
