Yahoo Mail Is Bouncing to the Sender

By Brian Flax

Occasionally, email that you send from your Yahoo mail account may bounce back. This may be for a number of reasons, including typos in the email address, inactive accounts or accounts that have reached their storage limits. Some of these issues you can fix on your end, but some must be handled by the recipient before your message can arrive correctly. Your first step is to figure out why the emails are bouncing back in the first place.

Storage Quota

You will usually receive an automated response from Yahoo with the details of the error any time you send a message to an address that has reached its storage quota. If the email cannot be sent due to a storage quota, the person receiving the email must either delete messages from his inbox to clear space, or upgrade to a plan that allows a higher storage limit. If emails you are sending to a particular address are repeatedly bouncing back, Yahoo may stop sending automated error messages altogether.

Address Book

Check the email addresses listed in your contact list to make sure they're up-to-date with the most recent data. If your friends or colleagues have updated their email addresses, make sure you've also updated their contact information within your Yahoo mail account. This information won't update automatically, and messages will bounce if they're sent to an email address that doesn't exist.


Yahoo mail has spam filters that automatically reject emails from known spam sources. Sometimes, legitimate emails may get caught in these spam filters and never reach your inbox. To ensure that you receive all your messages, check your spam folder frequently. You can mark messages as "Not Spam" from within this folder and move them to your inbox. This will prevent Yahoo from marking messages received from that sender as spam. You can also mark messages as spam in your inbox to move them to the spam folder.

Email Spoofing

Sometimes spammers may "spoof" your email address to make it seem like messages are coming from your address. This is done to help bypass spam filters to send junk mail to others. If this happens, you may get bounce back emails delivered to your inbox even though your account has not actually been compromised. Unless you know who is spoofing your email address, or are able to track the IP address, there's not much that can be done to stop email spoofing. To avoid hackers and cut down on the risk of being spoofed, make sure you use a strong password and update it regularly.
