Email Common Reasons for Rebating and Resolving

Sending and receiving emails is something that many people do every day, but you will definitely receive some inexplicable bounces. I don’t know how to deal with them. In fact, we can pass The information prompt of the feedback feedback to determine the reason for the bounce letter, the following describes several common reasons for bounce and the solution, I hope to help you.

Bounce prompt: "Invalid User", "User not found", "User unknown"

Reason for bounce: The other user does not exist, because the mailbox address in the sender is incorrect. The sending server could not find the email address to be delivered.

Solution: We only need to confirm whether the address we filled in is wrong, and then re-deliver after correct.

Bounce prompt: "Quota", "Hard limit", "Storage allocation"

Reason for bounce: The other party's mailbox is full, we have delivered the mail, the mailbox has not enough Space is received, all will generate an error and return to your shipping address.

Solution: Use other contact methods to let the other party know that the mailbox is full, let him receive some letters or delete some spam to make room for receiving mail.

Bounce prompt: "not found", "Host", "bad host domain"

Reason for bounce: Cannot find the server name of the other party, mainly because when writing the email address , the domain name or host address behind @ is written incorrectly.

Solution: Check the email address to see if it is wrong.

Bounce reminder: "Exceeds", "Maximum message size", "Data size"

Reason for return: The sent mail is too large, the other party's mail server refuses, and now many mails The server must limit the size of the sent mail. You can go to the website that provides the email address.

Solution: If the mail you send is relatively large, you can split the mail before sending it. For example, you can use OE to split the mail.

Bounce reminder: "Too many", "Less than 20"

Reason for bounce: There are too many users in the mail group, and some mail servers have a number of users for one mail. Restricted, this error will occur if this limit is exceeded.

Solution: We can control the number of users sent each time to about 20 people. If it is over, it can be sent several times.

Backward prompt: "Connection timed out"

Reason for bounce: The connection timed out is mainly caused by a network problem when connecting to the other server, causing the mail to be sent incorrectly.

Solution: We can try to send the message a few times. If it doesn't work, then send the message after a while.

There are many reasons for the bounce of mail, so I will not explain them one by one. You only need to carefully set up the mail to be sent, and try to avoid the mail bounce, so as not to affect your work and study.
