+======================================================================================
+Feature: #78332 - Allow setting a default replyTo-email-address for notification-mails
+======================================================================================
+
+See :issue:`78332`
+
+Description
+===========
+
+Two new LocalConfiguration settings are introduced:
+
+.. code-block:: php
+
+	$GLOBALS['TYPO3_CONF_VARS']['MAIL']['defaultMailReplyToAddress']
+	$GLOBALS['TYPO3_CONF_VARS']['MAIL']['defaultMailReplyToName']
+
+Also a new function to build a mail address for SwiftMailer from these settings is introduced:
+
+.. code-block:: php
+
+	MailUtility::getSystemReplyTo()
+
+If no default reply-to address is set this function will return an empty array.
+
+This function is used in :php:`ContentObjectRenderer::sendNotifyEmail()` to set a ReplyTo address in case no address was supplied in the function parameters.
+In other places where notifications are sent for e.g. (failed) login attempts, reports and where the notification uses the system from address this function is also used.
+
+
+Impact
+======
+
+It's now possible to set a reply-to address for notification mails from TYPO3. Extensions can also use this system reply-to address by calling :php:`MailUtility::getSystemReplyTo()`.
