# Exclude disclaimer from Smart Classification

Your mail server may add (legal) disclaimers to outbound emails. It is recommended to let Zivver ignore the content of the disclaimer when classifying emails for sensitive data. If your mail server adds disclaimers to outbound emails, please follow the instructions below for Exchange Online, or add the HTML tag to your preferred disclaimer-adding software.

Follow the steps below to exclude your disclaimer from [Smart Classification](https://docs.zivver.com/en/admin/general/smart-classification.html):

01. Contact the [Zivver Support team](https://support.zivver.com/s/contactsupport?language=en_US) to request exclusion of the disclaimer from Smart Classification.
02. Go to the [Exchange Admin Center](https://admin.exchange.microsoft.com/).
03. Click on _mail_outline_ **Mail flow** in the menu on the left.
04. Click on **Rules**.
05. Search for the rule that adds your disclaimer.
06. Click the name of the rule.
07. Click _content_paste_go_ **Edit rule conditions**.
08. Scroll down to the **Do the following \*** section.
09. Click on the _edit_ icon next to the disclaimer text.
10. At the top of the existing text, add a new line with the following content:

```html
<p style=" position: absolute; width: 1px; height: 1px; padding: 0; margin: -1px; overflow: hidden; clip: rect(0, 0, 0, 0); white-space: nowrap; border: 0; "> --&nbsp;<br /><br /> </p>
```

_This special tag tells the Zivver Gateway to ignore all text below it._

11. Click **Save**.
12. Click **Save** again.
13. Click **Done**.

Your disclaimer rule is now updated to start with a tag that tells the Zivver Gateway to ignore the rest of the disclaimer.
