Error 546: Email looping

What Is Causing This Error?

The SMTP error 546 issue often relates to your SMTP server settings and not the SMTP plugin you use.

It occurs when an email message gets stuck in a loop between the SMTP server and the email client. Thereby preventing the email from reaching the intended recipient(s).

This error can be caused by a variety of reasons. The most common causes include; misconfigured email forwarding rules, auto-responder conflict, or mail server configuration issues.

Resolving the Error – Solution

To resolve this error, first verify that the email forwarding rules are configured properly. If it is set to redirect to the same recipient, you’ll likely encounter a loop that’ll prevent emails from delivering.

We also suggest reviewing email aliases to confirm that they do not inadvertently create loops. This can occur when an email alias is sending emails back to an address that triggers the initial email forwarding.

If auto-responders are causing the loop, we suggest adjusting their settings to prevent them from responding to each other. You can implement this by adding conditions or limitations on when to send automated replies.

That’s it! Now you know the causes of the ‘error 546: email looping’ issue and how to resolve it.
