Email bounce back errors are frustrating to everyone, especially when you don’t know why the message bounced.
These types of errors are common, whether you have Shared Hosting or a Dedicated Server, it is likely you’ll encounter an email bounce back error at least once in your life.
In this article, we will explore email bounce backs, what they are, common errors, and how you can prevent them in the future.
Whether it’s for personal or professional purposes, you’ll be able to understand and ensure your emails always reach their destination.

What is an Email Bounce Back Error?
An email bounce back occurs when an email doesn’t reach your recipient, and instead you get back a Non-Delivery Report (NDR).
This can happen for a variety of reasons, but in its simplest form it is a way for the sender and recipient mail servers to communicate.
These messages typically contain information on the failure, allowing the sender to take the needed steps to resolve the problem and establish communication.
Types of Email Bounce Back Errors
Types of email bounce back errors fall into two main categories, hard bounces and soft bounce, with the addition of general errors and blacklisted messages.
Hard Bounce
A hard bounce back occurs when an email is permanently undeliverable to the intended recipient.
It typically happens due to reasons like an invalid or non-existent email address, a blocked domain, or a recipient’s server that no longer exists.
Hard bounces let the sender know that further delivery attempts to the given address are likely to fail every time.
Soft Bounce
In contrast with hard bounces, soft email bounce backs suggest that there is still a possibility for a successful email delivery in the future.
A soft bounce back indicates a temporary delivery failure.
It occurs when the email cannot be delivered temporarily, often due to issues like a full mailbox, a temporarily unreachable server, or a message that exceeds size limits.
Common Errors
Now that you understand the difference between soft and hard bounce back errors, let’s take a look at the most common ones seen in email communication.
Hard Bounce Back Errors
1. Incorrect / Unknown Email Address
When a user sends an email to an address that isn’t spelled correctly, or doesn’t exist, the receiving server will bounce it back.
Typically this bounce back will have information such as:
- The email address you tried to reach does not exist.
- User Unknown
2. Spam Filters
If a user has a specific spam filter to reject emails from certain senders, subject lines, or keywords, infringing emails will not be delivered.
Ensure your email does not read as spam, and that your sender reputation is in good standing in order to avoid this error.
3. Blocked Sender / IP Address
When users block a specific email address or a server’s IP address, emails will be automatically rejected by their email provider.
It is possible that the recipient’s email provider blocked your server’s IP address if it suspects you are sending spam. We will further discuss this under the Blacklists section below.
This is a permanent email bounce back as the only path forward to email delivery would be for the recipient to unblock or whitelist your email account or IP address.
4. Email Attachments
Email providers have varying file size and file type restrictions; however, if the host of your recipient does not approve the attachment you sent, they will reject your email.
If you need to send a specific file to someone, consider using a third-party drive like Google Drive, Dropbox, Box, or similar services.
Another option is to compress the file to make it smaller before sending it. This helps ensure smoother delivery and reduces the chances of encountering problems due to file size limitations.
Soft Bounce Back Errors
1. Inbox is Full
Most email providers have a limit to how many emails a person can store. When a recipient’s inbox is full, delivery will fail.
Once a user has more space in their inbox delivery will be successful.
2. Greylisting / Email Deferred
Greylisting is a style of spam filtering by a server that temporarily hinders emails from being delivered. This doesn’t mean your email was rejected, instead your server will attempt to resend this email after the deferral period is over.
The bounce back error will specify for how long the email is being deferred, this may look like the following:
- Server Error: Greylisted, please try again in X seconds
Although this issue is temporary, you can avoid email deferral by requesting your recipient to whitelist your email address.
3. Server Timeout / Connection Error
If the recipient email server is overloaded or down, emails will fail to be delivered as they have nowhere to go.
This bounce back is temporary and the only resolution is to wait for the recipient’s server to accept deliveries again.
Sometimes your email provider will try to automatically send the email again after a couple of hours and provide further information if it is not able to resend it again.
4. Server Error
Similarly to the error above, sometimes connections to the recipient server will fail, resulting in a “Message not Delivered” bounce back.
This error can occur because of a variety of reasons, but it is something that usually resolves on its own.
Technical details such as why the connection failed are usually provided in the bounce back message.
5. Send Limit Exceeded
Hosting providers may limit the number of emails an account (usually on Shared servers) can send per hour. This measure prevents the sending of spam and safeguards the entire server’s email reputation.
This type of error will specify how many emails per hour the account can currently send and the domain affected. If your business needs to send more emails than the ones allocated to your account, you can request an email extension from your email provider, though it may vary per host.
Blacklists and IP Reputation
An important aspect of your email health to keep up with is your email sender reputation and blacklists.
Blacklists
When a sender’s IP address gets blacklisted, it means it’s been labeled as sending spam or malicious content.
Email servers use a database to store these IPs, which helps prevent spam to their users and leads to bounce-back errors from the recipient server.
If your IP is on a blacklist, your email risks delivery to a spam folder or a full rejection.
IP Reputation
If your sender IP is blacklisted, or has previously been flagged as spam, this affects your IP reputation.
IP reputation refers to the overall trustworthiness and quality of an IP address.
A good IP reputation enhances the chances of successful email delivery, while a poor reputation can result in rejections.
How to Prevent Email Bounce Back
As a quick recap, here are the main five points you should follow to prevent email bounce back errors.
Keep in mind that some of these errors can occur outside of the user’s control, such as server connectivity issues.
- Double-check email addresses
- Maintain a clean email list
- Monitor your sender reputation
- Avoid excessive attachments or large files
- Monitor bounce back reports
Fortunately, there are also tools such as our bounce back parser tool and blacklist checker to keep up to date with your email server’s reputation.
Final Thoughts
Email communication is crucial for businesses and personal relationships alike, so understanding errors and their causes is crucial.
Bounce back errors are a form of feedback, as they aid in the process to successfully get in contact with your recipient.
Remember to double-check email addresses, avoid excessive attachments, and maintain a healthy sender reputation to minimize bounce backs.
I have a client who is trying to forward me attachments that they received that have invoices or receipts and they are not able to. They keep getting rejection emails from my Google and Outlook. This is the following message they get:
Your message did not reach some or all of the intended recipients.
This message could not be sent. You do not have the permission to send the message on behalf of the specified user.
I left out some information to keep it private but I was just wanting to know if it is something on my end or on their end. I am not seeing that I blocked their email or contents so I am not sure what to do to resolve this issue. He is able to send me an email without attachments so it must be something about those particular attachments.
Hello Natalie,
This is difficult to troubleshoot without the full bounceback. If you could, please reach out to our Technical Support team directly with that information through chat at https://inmotionhosting.com
This article did no solve my enquiry. For over 6 months now, our emails do not deliver to yahoo and Gmail accounts. Kindly help rectify or provide directions on how to resolve it.
Hello, if you’re having trouble sending to Google or Yahoo, please reach out to our Technical Support team directly at https://www.inmotionhosting.com/contact for further assistance.
Hello Team,
i want to ask you about emails deliver with a hug delayed to the microsoft server (mail.protection.outlook.com) each email deliver after one or two days and sometimes i get email back that the remote server is busy any advice.
i have contact the microsoft team about this issue but without luck.
Best Regards
A “remote server is busy” message indicates that the email is being delivered to the recipient server, but it may be having issues. The recipient should review the mail logs on their server, or contact their mail host to verify if they are having mail server issues.
Thank you,
John-Paul

What can I do to stop all these emails bouncing – there have been 18 bounces since the 1st February 2017 !
I recommend contacting Live Support so they can test and replicate from your specific server and domain.
Thank you,
John-Paul
Please explain what a MX record is? Thanks for your help.
Set up new account and receive errors no matter what, no send or receive. Double checked spelling and server config – all ok. all 550 errors. Stumped.
Hello Network Admin,
Sorry for the problems you’re having when setting up your email. Can you please provide some details on your account such as email address, domain name/account name? We would need a little information in order to troubleshoot the issue. If you are not an InMotion customer then you may need to speak with the support team for your email server host.
If you have any further questions or comments, please let us know.

hello bonny,

when i send a mail from outlook with attachments then after a few minutes a mail came back . in that mail mention that the reason is over quota
and also the is from named internet mail delivery
pls help me to resolve it
your’s faithfully
shahid shan
It sounds like the recipient’s mailbox is full and cannot receive any more messages. Unfortunately, there’s nothing you can do about someone else’s mailbox being full. Alternatively, it could be that you have sent too many messages and the email is being returned because your provider has a limit. Can you paste the bounceback message for us to review?
Dear Sir,
I didn’t send the email to liponcu@*****.com but I am getting the following email in my gmail inbox.
So pls help me how can I stop to sending the email in liponcu@******.com
I recommend changing your email password immediately, be sure to use a strong password.
Also, check any contact forms, or mailing programs that use your address. For example, ensure they are up-to-date.
Thank you,
John-Paul

Hello,
Sorry for the problem with the email delivery. It appears that the email delivery is being done by Google. You may need to contact their services. When you look at the error, click on the link they have provided: https://support.google.com/mail/answer/69585. It will give you information about why the email is not being delivered. Since the error message indicates that the delivery was handled by Google, you will need to have them resolve the issue. If you are an InMotion Hosting customer, then please provide the entire bounce-back message so that we can investigate the issue in more depth.
I hope this helps to answer your question, please let us know if you require any further assistance.

Hello Bonni,
Thank you for contacting us. Is she able to email you from her gmail address?
We are happy to help troubleshoot further, but will need a full copy of the bounced/returned email to investigate further.

When i google about this issue I keep seeing people list the reasons…. i don’t care about that I just want to know where I can find it to try to resend it now that I have corrected the issue…. can anyone please help me?
Hi Crissy,
You could look in your sent folder to copy the email. However, there’s no specific way to re-send the email once it has failed. I’d suggest cut & paste to re-create it to send again.
Thanks!

My Customer service agents get this error msg now and then. Company wide we do not generate over 250 emails in an hour. Is there a way to track senders to find out which accout might be causing this?

Hello Scot,
Sorry for the problem with the emails. The problem can stem form a simple chain of forwarding. For example, invoicing emails are often sent to more than 1 person. So, if there are 100 invoices and it’s sent to 3 people, then 300 emails are generated pretty quickly. When I looked at recent activity in your accuont, the most emails generated was from invoicing@ with a total of 323. If that happened within an hour, it would have hit the mail limit. You can always request for extension of the limit through AMP as necessary.
I hope this helps to answer your question, please let us know if you require any further assistance.

Hello Tom,
Thank you for your question. I looked up the whois for your domain with godaddy, and your website is hosted with us (via “A record”), but your email is hosted by google.
I was able to tell, because your MX records are pointed to google as can be seen here:
thenagleragency.com. 3600 IN MX 5 ALT1.ASPMX.L.GOOGLE.com.thenagleragency.com. 3600 IN MX 5 ALT2.ASPMX.L.GOOGLE.com.
thenagleragency.com. 3600 IN MX 10 ASPMX2.GOOGLEMAIL.com.
thenagleragency.com. 3600 IN MX 10 ASPMX3.GOOGLEMAIL.com.
thenagleragency.com. 3600 IN MX 1 ASPMX.L.GOOGLE.com.
To get your email going, set it up with google; or host your email with us by pointing your MX records to us, then allow up to 24 hours for propagation to complete.
If you have any further questions, feel free to post them below.
Thank you,
-John-Paul

I followed your tutorial on receiving our mails from Gmail account
Hello Iamkingsleyf,
Thank you for contacting me. If you just made changes to your DNS, it may take some time to propagate.
We are happy to help further, but will need some additional information.
How did you setup your email with Google?
If you have any further questions, feel free to post them below.
Thank you,
John-Paul
Hello Iamkingsleyf
Thank you for the information. When you set up Gmail for POP3 and SMTP, were you able to complete the guide successfully?
Typically an AUTH failed with the remote server error means the email address, or password is incorrect.
If you have any further questions, feel free to post them below.
Thank you,
John-Paul
Our emails are not reaching our customer. The rejected response below.
This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:

SMTP error from remote mail server after RCPT TO:<[email protected]>:
host mail.example.com [123.123.123.123]: 550 5.7.1 Your IP has been found on block list ix.dnsbl.manitu.net
As this is a public post I’ve gone ahead and removed the email address you’ve mentioned in your bounce-back error.
It looks like the particular mail server that handles mail for the person you were trying to reach, had either our server’s IP address, or your own home IP address in a mail blacklist.
These are generally temporary problems, and you might be interested in learning about why mail servers get blacklisted and also how to request a delisting from a blacklist.
I went ahead and requested a delisting from the ix.dnsbl.manitu.net blacklist mentioned in the bounce-back, and it doesn’t look like our IP address is listed any longer.
Please let us know if you’re still having any issues at all.
