Hi I upgrade my magento 2.2.3 to 2.2.8 where I have some custom functionality for emails.

After upgrading am getting

Fatal error: Uncaught Error: Call to undefined method MagentoFrameworkMailMessageInterceptor::clearFrom() 

Fatal error: Uncaught Error: Call to undefined method MagentoFrameworkMailMessageInterceptor::getRawContent() 

I have made plugin for public function MagentoEmailModelTransport

 beforeSendMessage(MagentoEmailModelTransport $subject)
 
 $message = $subject->getMessage()
 $body = $message->getBody()->getRawContent();
 $message->clearFrom();
 $message->setBody($bodyNew);
 

its MagentoFrameworkMailMessage

buddy I just check that class I'm also gonna share as well that class
MagentoFrameworkMailMessage;

<?php
/**
 * Mail Message
 *
 * Copyright © Magento, Inc. All rights reserved.
 * See COPYING.txt for license details.
 */
namespace MagentoFrameworkMail;

class Message extends Zend_Mail implements MessageInterface

 /**
 * @param string $charset
 */
 public function __construct($charset = 'utf-8')
 
 parent::__construct($charset);
 $this->setHeaderEncoding(Zend_Mime::ENCODING_BASE64);
 

 /**
 * Message type
 *
 * @var string
 */
 protected $messageType = self::TYPE_TEXT;

 /**
 * Set message body
 *
 * @param string $body
 * @return $this
 */
 public function setBody($body)
 
 return $this->messageType == self::TYPE_TEXT ? $this->setBodyText($body) : $this->setBodyHtml($body);
 

 /**
 * Set message body
 *
 * @return string
 */
 public function getBody()
 
 return $this->messageType == self::TYPE_TEXT ? $this->getBodyText() : $this->getBodyHtml();
 

 /**
 * Set message type
 *
 * @param string $type
 * @return $this
 */
 public function setMessageType($type)
 
 $this->messageType = $type;
 return $this;
 

so as you can see that there is no any function getRawContent() or clearFrom() so they may updated that as well in the updated version thats why its not working
