Error 550 5.1.1

This type of useless automated message is called backscatter. Then verify that the domain has valid DNS records by doing an external DNS lookup.

IB113 This IP address has attempted to mail too many invalid recipients and has been blocked for the remainder of the day.

The first is a Domain Not Found error, where the sender's domain could not be found: :host img10.ppi.net said: 554 : Sender Address Rejected: domain not found Unlike the Domain Not You should try to reduce the size of the message, or try to split the email into smaller parts and resend it.

They’ll have to resolve the issue in order to prevent NDR 5.1.x errors. I’m not going to try again; this message has been in the queue too long. Notice the "Sender Address Rejected"; this means that the problem is actually with the Sender's email address - specifically, that the domain used in the sender's email address was not a There is something wrong with the configuration of the receiving server.

There are no other user accounts for the site, just a single "admin" account which is a catchall for the domain. @domain.tld web48_admin is listed in /etc/postfix/virtusertable, which I assume refers It may be a problem with DNS (the MX record) as DKNUCKLES stated or it may be a problem with the Exchange configuration.

I have just changed the record back to the original IP, just in case that has anything to do with it. IB112 This IP address has attempted to mail too many invalid recipients and has been blocked for an hour. At times, a typo in the email address of the recipient can cause this email delivery failure. Most of the time, your email provider will need to contact the system administrator to have the block removed, so you should contact your provider immediately.

These errors mean that your provider's domain name (or specifically, your email address) is explicitly listed as a known spammer on a blacklist.
