5.1.0 message size exceeds limit tca mail limit

A pesky error!

The error "5.1.0 message size exceeds limit TCA mail limit" typically occurs when you're trying to send an email that exceeds the maximum allowed size limit set by your email service provider or the recipient's email server.

Here are some possible solutions to help you resolve this issue:

  1. Check the email size: Verify the size of the email you're trying to send. You can do this by checking the file size of the attachments or the total size of the email, including the body and any attachments. If the size is too large, you may need to reduce the size of the attachments or break up the email into smaller parts.
  2. Check the email service provider's limits: Check the email service provider's (ESP) limits for message size. Most ESPs have a maximum allowed size for emails, which can range from 10MB to 25MB or more. If your email exceeds this limit, you may need to reduce the size of the email or use a different ESP.
  3. Use a smaller attachment size: If you're attaching large files, try reducing the size of the attachments or using a file compression tool to reduce the file size.
  4. Use a third-party email service: If you're using a third-party email service, such as Mailgun or Sendgrid, check their documentation for message size limits. Some third-party services may have more generous limits than your ESP.
  5. Split the email into smaller parts: If you're sending a large email with multiple attachments, consider splitting the email into smaller parts and sending them separately. This can help avoid exceeding the message size limit.
  6. Check for any other issues: If none of the above solutions work, check for any other issues that may be causing the error, such as a faulty email client or a problem with your email server.

Remember to always check the documentation for your email service provider or third-party email service to ensure you're aware of their message size limits and any other requirements for sending emails.
