Why am I getting this error?
To help in the global battle of ever-increasing SPAM, hosting company’s have implemented spam detection procedures on all emails prior to leaving their email servers. Each email is evaluated and rated according to spam rules to determine how likely they are to be actual spam. Those that fail the test are returned to the original sender with the error message 550 This message was classified as SPAM and may not be delivered (please see the email below). If you are receiving a bounceback with this error, then the email you sent has not passed the outbound filter.
Why are you doing this on outbound emails?
Although email servers review all incoming email and evaluate it against their own filters, hosting company’s have begun screening outbound emails to help preserve the reputation of their server’s IP addresses. This is a safety measure enabled to protect all clients being hosted in the Shared Server environment. Once a mail IP gets enough SPAM complaints against it, it will be reported to a company that maintains a blacklist. Any email server that subscribes to that particular service will then block any incoming email from that IP address. After too many times on a blacklist, any email sent from that hosting company’s servers have the chance of automatically being delivered to SPAM folders, regardless of the IP address of the server. Also, since many of the hosting company’s customers are on shared servers, we feel it is not fair for your emails to be blocked due to the SPAMMING activities of other customers. Outbound SPAM evaluation is a proactive measure to prevent blacklisting and keep your email server up and running.
Common solutions to the error
Solution #1 – Enable SMTP Authentication in Outlook
If you are using the Microsoft Outlook email client, not having SMTP Authentication will cause several points to be added to the SPAM score. This can cause emails that otherwise would be allowed through to be classified as SPAM.
Solution #2 – Evaluate email content (See chart below)
As our outgoing servers are using a SPAM evaluation software set at the most lenient levels, it is difficult for your emails to be tagged as SPAM and prevented from going out unless they have a lot of features of a SPAM message. If you are getting caught by the filter, evaluate both the title and body content of the message to ensure there are few, if any, references to popular SPAMMING terms. Also be sure not to include multiple live links to several other websites as this can affect the email rating with the SPAM software.
