SMTP Error 446

What Is Causing This Error?

The SMTP 446 error typically occurs when the maximum hop count is exceeded. Hop count is the number of servers an email message has to pass through before getting to the recipient. This error may occur if one of the servers triggers numerous redirects when sending an email.

The error could also occur on sites using Microsoft’s email API. It often indicates you’re trying to send emails through an unverified domain.

Resolving the Error – Solution

To fix this error, you’ll need to increase the hop count on the SMTP server you use. This can easily be done by contacting your email service provider.

If you’re encountering this error while using Microsoft’s API to send emails, you’ll need to make sure your domain is verified. Domain verification usually involves adding the provided SPF, DMARC, and DKIM records to your DNS settings.

That’s it! Now you know how to fix the 446 SMTP error.
