Can send mail exchange submission quota exceeded limit

A very specific and technical question!

When you see an error message saying "Send mail exchange submission quota exceeded limit", it typically means that the mail exchanger (MX) server that is responsible for sending your emails has reached its submission quota limit.

Here's a breakdown of what's happening:

  1. Mail Exchanger (MX) server: An MX server is responsible for receiving and sending emails on behalf of your domain. It's usually provided by your email service provider or your own mail server.
  2. Submission quota: The submission quota is a limit set by the MX server on the number of emails that can be sent within a certain time period (e.g., per hour, per day, or per week).
  3. Exceeded limit: When you try to send more emails than the submission quota allows, you'll receive an error message indicating that the quota has been exceeded.

This error can occur for several reasons:

  1. High email volume: If you're sending a large number of emails in a short period, you may exceed the submission quota.
  2. Spam filtering: If your emails are being flagged as spam, the MX server may limit the number of emails you can send to prevent abuse.
  3. Server overload: If the MX server is experiencing high traffic or technical issues, it may temporarily limit the number of emails you can send.

To resolve this issue, you can try the following:

  1. Wait for the quota to reset: If the quota is reset after a certain time period, you can try sending emails again after the reset.
  2. Reduce email volume: If you're sending a large number of emails, try reducing the volume to avoid exceeding the quota.
  3. Contact your email service provider: Reach out to your email service provider or mail server administrator to ask about increasing the submission quota or resolving any technical issues.
  4. Use a different email service: If you're using a free email service, you may want to consider switching to a paid service that offers higher submission quotas.
