When using QQ mailbox, we are sending emails to friends, but we find that the email cannot be sent out. We don’t know what the reason is. So let’s take a look at the reasons why QQ mailbox cannot send emails.
1. Your own problem: Wrong recipient address of emails is the main reason for bounced emails. The address contains characters that are not allowed, and there are spaces that should not appear in the entered recipient address.
2. The other party’s problem: The recipient’s mailbox or the recipient’s mail service provider caused the mail to be undeliverable. The recipient's mailbox is full or there is no space left to accommodate new messages.
3. Network problems: Unstable network communication quality or too slow network speed prevents emails from being sent successfully.
4. It prompts that the sending failed and there is a bounce message. The sender of the bounce email is not @qq.com, which is caused by the recipient actively bounced the email.
5. It prompts that the message was sent successfully, but the other party cannot receive it. The QQ mailbox server shows that it has been successfully sent to the other party's server. This may be caused by the recipient's settings or the other party's server intercepting it.
1. Sending and receiving letters: Using email, users can not only send regular letters, registered letters, and urgent letters, but can also ask the system to send a notification back after the other party receives the letter, or to read the letter and send a message back, etc. In addition, there are functions such as scheduled sending, replying immediately after reading the letter or forwarding it to others, and multi-casting.
2. Direct delivery : If the other party is a non-mailbox user, the letter can be sent directly to the other party's fax machine, telex machine, printer or packet switching network computer.
3. Bulletin Board: A bulletin mailbox for everyone to use. Users can send the information they want to publish to this mailbox for everyone to read. Bulletin boards are suitable for announcements, notices and advertisements.
4. Roaming function: National roaming can be achieved using the packet switching network.
