reworked allowed and denied addrs for routes The following refactorings had been made: - allowed_mail_locals + allowed_return_paths -> allowed_senders - not_allowed_mail_locals + not_allowed_return_paths -> denied_senders - allowed_rcpt_domains -> allowed_recipients - not_allowed_rcpt_domains -> denied_recipients The new options allow more consistent and more flexible matching.

void hmac_md5(
	unsigned char* text,   /* pointer to the message */
	int textlen,           /* length of the message */
	unsigned char* key,    /* pointer to the authentication key */
	int keylen,            /* length of the key */
	unsigned char* digest  /* pointer to allocated memory to store the computed HMAC */
);
