Who is “MAILER-DAEMON”?
Mailer-Daemon is a mail server program, not a person. If you received email from the mailer daemon, the message is most likely a notification that there were either temporary delay problems, or that there were permanent failures while attempting to deliver an email that you sent. In the top section of the email you received from the mailer daemon, there will be a brief description of the error. Check the rest of this section of the FAQ for some examples of messages you may receive and what they mean. If you are at any point unsure of what a particular message means, and you would like to know or just be sure that your email will be delivered, please forward the original message from the mailer daemon with a short note to support@impulse.net or use other ways to contact us.
