# Important: #97159 - MailLinkHandler key in TSconfig renamed {#important-97159}

See [forge#97159](https://forge.typo3.org/issues/97159)

## Description {#description}

The key for the `MailLinkHandler` in the `TCEMAIN.linkHandler.`
TSconfig has been renamed from `mail` to `email`.

This is done to be consistent with the identifier, used for the
`$GLOBALS['TYPO3_CONF_VARS']['SYS']['linkHandler']` registration,
as well as the value of the `LinkService::TYPE_EMAIL` constant.

Update any usage of this key in your extension code.
