A 552 email error is typically ecountered when there is a problem related to an attachement in your email. Either it has exceeded the size limits of the remote server, or the file-type isn't allowed by the remote server. Some mail servers also seem to use this error code incorrectly when blocking a message due to triggering a filter such as a URL in the message being found in a domain black list.

You should receive a bounce-back message from the server with a variation of email error 552 in the subject, and the body should contain your original message that you attempted to deliver.

Resolving a 552 email error bounceback

The 552 series of errors can sometimes be a soft or hard bounce. For a more in-depth review of what a soft or hard bounce is, and general email bounceback reasons you can read why does email bounce, bounceback, or error?

In our example bounce-back error above the reason the message has failed is because the server for has a fixed message size limit. The attempted message exceeded this limit so it was not accepted and generated this bounce-back error.

Very straightforward and easy to understand explanations, to problems which, if explained differently, would make the average Layman's head fall off!

Maybe suggest a solution, (Error 552 size limit exceeded), or does this issue need to be resolved by the recipient? Thanks, Andy Cooper

Hello Andy Cooper,

The solution depends on the error and yes, many of these will require action by either the recipient or the sender. In some cases, if the email is too large for the recipient, then either the sender needs to find an alternate way of sending the message, or the receiver needs to make it possible for the size of the email to be able to received (this would be generally done by the email server administrator).

In other cases, the email account may be full and the recipient needs to clear space in order to receive it. So there are many variants as to how this particular error can appear, but the action that is required depends on the wording of the error message being sent. It's generally self-explanatory. However, if there is a confusion in interpreting the error message, then the sender should contact our live technical support team for further clarification.

Kindest regards,
Arnel C.

Hello Ncedo,

Unfortunately your post does not give any details about why the message was not delivered. You may want to check out our bounce back parser tool that may help give an explanation. If not, you may want to contact our Live Support to have them check into the server logs (assuming you are one of our customers)

HI,Need a support on Email Bounce back. Yesterday evening we have sent an email with attachment of 8MB in size. And we got a bounce back message that the Message size exceeds the fixed limit.


The error that the other server returned was: 552 5.3.4 Message size exceeds fixed limit.

I can understand about the attachment limits.My question is why we are getting the bounce back after 12 hours. Generaly it should bounce back immediatly.Please advise on the same.Thanks & RegardsK Shyam kumar

Hello Shyam,

Email was never meant to be instant, so if emails or even returned emails do not come back immediately, it is neither uncommon nor an issue. It seems the attachment size for the receiving server is hard set for their security reasons so you would just need to know the size limit. Perhaps you can compress the file to be under that limit.

As for the return taking 12 hours, email is as email does. Delays can be caused by queues on the sending server or during any one of the stops in between. Although we are used to getting emails very quickly, delivery time within 24 hours was the original design and at times you will see delays of a few hours, even for bouncebacks.

Kindest Regards,
Scott M

Hello Christo,

Sorry for the error you're getting. The problem is usually due to restrictions at an email host. If your friend is unable to receive the file, then you should either split the file so that it's smaller, or use a service or option like Google Drive, where you can share the file and then your friend can download it, in spite of its size. If your friend has file size restrictions, then sharing the file with something like Google drive is the most cost effective way to handle it, because its' free!

Kindest regards,
Arnel C.

Hello Shaun,

This error is stating that the email address you are sending too has run out of disk space allotted to them. There is nothing you can do on your end.
