Delivery to recipients via relay server


In general, "delivery via relay smtp server" mode is always used by the senders who can not

directly submit mails to the recipients' server. The "successful delivery" hint given by relay smtp

server just tells if the mails have been successfully delivered to your ISP, but can't know wheather the

mails have been successfully delivered to your recipients' mailbox. QK offers more detailed log that

notes which steps of sending failed. QK also can send multi-mails at the same time.
