public function getReplyTo(); public function setReplyTo($value);
ipworkssmime_ssmtp_get($res, 46 ); ipworkssmime_ssmtp_set($res, 46, $value );
If this property contains a non-empty string, a Reply-To SMTP header is created for the message. This header shows the address to use for replies (useful if this address is different from the one in From).
If the resulting header is longer than MaxHeaderLength, then it is folded according to RFC 822 specifications.
