A bounce message, or Delivery Status Notification (DSN) message is an automated e-mail from the receiver's mail system telling the Sender that their message could not be delivered. The original message is said to have bounced. Errors can occur at multiple places in mail delivery. A user may sometimes receive a bounce message from their own mail server, and sometimes from a recipient's mail server. With the rise in forged spam and e-mail viruses, users now frequently even receive erroneous bounce messages sent in response to messages they never actually sent. Most Common Reasons for Bounced Messages Bounce-back messages from the recipients mail server almost always contain an error code or explanation. By reading the bounce-back message carefully, you can usually immediately know why your message was rejected. The most common reasons are:
America Online (AOL) Blocks/White List Procedures AOL regularly blocks domains, ISPs and/or hosts based on spam complaints or what they consider excessive use. If you find you suddenly cannot e-mail anyone at an AOL address, you may be blocked. If you are blocked, your bounce-back message(s) will look something like this: Delivery failed 2 attempts:
janedoey@aol.com 421 SERVICE NOT AVAILABLE To resolve, follow the link in AOL's error message to their Explanation and Solution page. Apply for a Feedback Loop or White List, depending on which applies to your needs. If you have any questions, contact AOL directly. Verizon Blocks/White List Procedures Verizon regularly blocks domains, ISPs and/or hosts (and even entire countries) based on spam complaints or what they consider excessive use. If you find you suddenly cannot e-mail anyone at an Verizon address, you may be blocked. If the error message you or the person trying to contact you receives is a 550 error that has a link to http://www.verizon.net/whitelist, then you have been blocked. To resolve, follow the link in Verizon's error message to White List Request Form and follow their instructions. If you have any questions, contact Verizon directly. Disclaimer: Please read all bounce back messages carefully. Web Panache can only trouble-shoot global issues concerning our own mail servers or your e-mail account settings, not third party delivery problems or individual bounce back messages. If a global block is discovered at the host level and not your specific domain, Web Panache will follow the provider's White List procedures when possible and if offered, however, third party ISPs reserve the right to keep blocks in place arbitrarily. Because of this, Web Panache cannot guarantee a resolution, nor continued or consistent mail delivery to any particular ISP. Customers of third party ISPs are encouraged to complain directly to them if they feel e-mail from you is being unfairly blocked. Similarly, Web Panache periodically blocks IPs or ranges of IPs owned by third party ISPs when it is determined such IPs have flooded our server(s) with SPAM. We reserve the right to keep such blocks in place if deemed necessary to protect the global service even if it impacts your account(s) individually. Related Articles: Spam FAQs
