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 RemoteDomains.com has a fixed message size limit. The attempted message exceeded this limit so it was not accepted and generated this bounce-back error.
