A message that you sent could not be delivered to one or more of its<br>recipients. This is a permanent error.

The first part is the error number, and the second is the message. The 550 error number means that this is a permanent error, so resending it later will have the same effect. Error numbers that are in the 400&#8217;s are temporary errors and can usually be tried again at a later time.<\/p>\n\n\n\n<p>The message itself indicates that the email address that the message was sent to does not exist. Typically, this means that the receiving server does not have an account registered to that email address. This can be from a recent change in DNS records, or the email address was deleted.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"variations\">Common Variations of the 550 Email Error<\/h2>\n\n\n\n<ul class=\"wp-block-list\"><li>550 No such person at this address<\/li><li>550 No such recipient here<\/li><li>550 No Such User Here<\/li><li>550 No such user \u2013 psmtp<\/li><li>550 No such user (recipient@RemoteDomain.com)<\/li><li>550 permanent failure for one or more recipients<\/li><li>550 Recipient does not exist here<\/li><li>550 Recipient Rejected: No account by that name here<\/li><li>550 &lt;recipient@RemoteDomain.com&gt;: invalid address<\/li><li>550 &lt;recipient@RemoteDomain.com&gt;&nbsp;No such user here<\/li><li>550 recipient@RemoteDomain.com\u2026User unknown<\/li><li>550 Rejected<\/li><li>550 relaying denied<\/li><li>550 Requested action not taken: mailbox unavailable<\/li><li>550 Requested action was not taken because this server doesn\u2019t handle mail for that user<\/li><li>550 sorry, no mailbox here by that name (#5.1.1)<\/li><li>550 sorry, no mailbox here by that name.
