* Hi
We have detected in some pages that messages are being received with HTML
tags visibles, like this:
* ```wp-block-code
…
```
* It happens if HTML mode is checked.
Also, if in additional headers we add “_reply-
to: [your-email]_” the received email doesn’t contain it. This bug occurs in
both cases, with plain and HTML emails.
* Thanks
