Error 553

Support Portal  »  Knowledge Base  »  Viewing Article

When sending email, if you receive a 553 "Unable to verify address" address error, this usually indicates a configuration setting in your mail client is not set correctly.

This error is usually a result of your email client not correctly authenticating with the mail server. This is only a small issue and can quickly be rectified.
  • Make sure you are using your full email address, for example:
  • Make sure you have enabled the setting "My server requires authentication"
  • Double-check all settings within email client.

The settings should be as follows:
  • Incoming Mail Server -
  • Outgoing Mail Server -
  • Username - your full email address
  • Make sure "My SMTP server requires authentication" is enabled
