How to Fix Hotmail Error 550-step

While transferring emails through Hotmail or windows live mail you may suffer from the error code 550. Basically, this is a server error. The most popular protocol used for an email client for outgoing mail is simple mail transfer protocol (SMTP). Whenever you receive the “550”  windows error in mail client such as Hotmail or windows live mail, this typically indicates that outgoing mail server is not responding to requests. You can also confirm if the error is “down” by using “ping” command in a MicWindowscommand prompt. Whenever the outgoing mail server is down, there is nothing you can do except to wait for the server to start responding again.

“The message could not be sent because one of the recipients was rejected by the server. Server Response: ‘550 not local host, not a gateway’, Port: 25, Secure (SSL): No, Server Error: 550, Error Number: 0x800CCC79. step to resolve this issue-

  1. Open your Outlook settings (Tools ->Accounts)
  2. Go to View/Change email account for the email account you are having problems with.
  3. Check that the SMTP Server is set to mail.yourdomain.com
  4. Go into the “More settings”, “Outgoing Server” tab and make sure that the option “My server requires authentication” for the Outgoing server is checked ON.
  5. Save and close all windows.
  6. Try again.

Another solution 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. You can find instructions on enabling that setting that in our Invalid HELO name article.

Solution-2 – Evaluate email content

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.
