Hello,
sorry for the late respons. I was creating a new newsletter but not sending it. I don’t know what the trigger is for the email I received afterwards. This text below is the content of that email:
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:
[email protected]
host mx1.dfw.automattic.com [192.0.84.151]
SMTP error from remote mail server after RCPT TO:<[email protected]>:
550 5.1.1 <[email protected]>: Recipient address rejected:
??? User unknown in local recipient table
I hope that this information can help you to solve this problem.
With regards, Wim
