Identifying and removing AOL mail delivery subsystem spam is relatively easy. This type of email is sent automatically by the mail delivery subsystem, or MAILER-DAEMON. You can identify bounced emails by their subject line, which says “Not Delivered.” This message contains the reason for the failure of delivery and the original message. Follow the instructions in this article to eliminate your AOL spam messages.
The most common reason for bounced emails is an invalid email address. The Mailer Daemon will attempt to deliver the email, but it may not succeed. The reason is often a single misspelled letter. The other common reason for bounced emails is the email address being closed or moved. If you are receiving this kind of spam, you should contact your mailbox provider and request them to fix the problem. Once you get these types of messages, you can start cleaning up the problem.
Mailer Daemon emails are a common sign of a spam problem. You may receive a seemingly endless stream of emails from this source. The message is either a forged or stolen email address, or the user has compromised their password. The Mailer Daemon uses an infinite list of email addresses to send spam, so check your settings. There are a couple of things you can do to help reduce the amount of spam you receive.
