QQ mailbox failed to withdraw mail, did the other party reject my mail?

It may be that the other party's mailbox is set to reject non-friends' mail (the mail restrictions of different websites are different), it may also be that the other party's mailbox has been recycled or cancelled by the system for a long time, or it may be that the network connection is temporarily interrupted and the mail transmission fails.

It's best to contact the other party first to confirm whether the mailbox stone of the other party is unblocked and whether the rejection screen setting is set. If there is a network problem, please refresh the page or try again with a different browser.
