Function Documentation

static int check_rfc822_headers ( unsigned int *  headerflags, const char **  hdrname  )

static

check if header lines violate RfC822

Parameters

headerflags	flags which headers were already found
hdrname	the header found on error

Returns

if processing should continue

Return values

0	nothing special found
1	a known header was found
-2	a duplicate header was found (hdrname is set)
-8	unencoded 8 bit data was found

static void date822 ( char *  buf )

static

write RfC822 date information to buffer

Parameters

buf	buffer to store string in, must have at least 32 bytes free

exactly 31 bytes in buffer are filled, it will not be 0-terminated

int smtp_data

(

void

)

handle DATA command and store data into queue

Returns

0 on success, else error code

static int write_received ( const int  chunked )

static

write Received header line

Parameters

chunked

if message was transferred using BDAT
