554 Malformed Email Rejected, Help With Emails Being Returned

A 554 email error is sometimes thought of as a catch-all of email errors. It is generally used when there is a generic delivery failure that another email error code doesn’t directly define a problem for.

Some mail servers also use a 554 error even if there is a specific error code that defines what went wrong already.

You should receive a bounce-back message from the server with a variation of email error 554 in the subject, and the body should contain your original message that you attempted to deliver.

Example bounce-back message

Resolving a 554 email error bounceback

Because errors in the 554 series don’t always bounceback for a common reason, they could be either a hard or soft bounce. To better understand soft and hard bounces, and general email bounceback errors 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 an auto-reply was trying to be sent to an account that didn’t exist. So the RemoteDomain.com mail server responded back with a 554 Invalid recipient error.
