Common solutions to the error
Solution #1 – Enable SMTP Authentication in Outlook
If you are accepting the Microsoft Outlook email client, not having SMTP Authentication will cause certain points to be added to the spam mark. This can cause emails that any other way would be granted through to be classified as spam. You can find information on enabling that setting that in our Invalid HELO name article.
Solution #2 – Evaluate email content
As our outgoing servers are using a spam estimate software set at the most lenient levels, it is tough for your emails to be tagged as spam and stopped from going out unless they have a lot of features of a spam message. If you are getting captured by the filter, estimate both the title and body content of the message to assure there are few, if any, quotation to popular spamming terms.
Solution #3 – Contact Live Support directly
If you have worked with the other solving above and are still having a problem with your emails getting classified as spam, you will want to contact our Live Support department. Simply forward the break-down email complete with the bounce-back headers to support@dboktechnologies.com and they will be able to test the email against the filter and find which rules were a breach
Why am I getting this error?
To help in the comprehensive combat of ever-expanding spam, we have achieved spam detection procedures on all emails prior to leaving our servers. Each email estimates and rated according to spam rules to regulate how likely they are to be certain spam. Those that declined 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, we have begun screening outbound emails to help preserve the reputation of our server’s IP addresses. 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 our servers has the chance of automatically being delivered to spam folders, regardless of the IP address of the server. Also, since many of our 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.
