550 209.85.210.194 is not allowed to send mail from

It looks like you're trying to send an email, but the IP address 209.85.210.194 is being blocked by the recipient's email server.

This is likely because the IP address is associated with Google's mail servers, and some email providers may block or flag emails from Google's IP addresses as spam or phishing attempts.

Here are a few possible solutions:

  1. Check your email settings: Make sure your email client is configured correctly and that you're not using a proxy server or VPN that could be causing the issue.
  2. Use a different email client: Try using a different email client or webmail service to see if the issue persists.
  3. Contact the recipient: Reach out to the recipient and ask them to check their email settings or whitelist your IP address (if you're sending from a specific IP address).
  4. Check your email content: Ensure that your email content is not flagged as spam or phishing by checking your email's subject line, body, and attachments for any suspicious or misleading information.

If none of these solutions work, you may want to contact your email provider or a network administrator for further assistance.
