# Breaking: #61783 - Removed deprecated mailing API

See [forge#61783](https://forge.typo3.org/issues/61783)

## Description

The deprecated methods to send email are removed.
This includes the `MailUtility::mail()` method, the mail delivery substitution API and the `plainMailEncoded()` methods.

## Impact

Any call to `MailUtility::mail()` or `GeneralUtility::plainMailEncoded()` will result in a fatal error.
The option `$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['t3lib/utility/class.t3lib_utility_mail.php']['substituteMailDelivery']`
does not have any effect.

## Affected installations

Any installation using an extension still using the deprecated API will fail.

## Migration

Use the `TYPO3CMSCoreMailMailer` API for sending email.
