There’s a major bug in Swiftmailer, where sometimes your email returns 0 bytes attachment, or broken html email, or broken plaintext email in Yahoo? Well the cause of this is that Swiftmailer wrongly sends header and body. They forgot to separate the two.

As you can see, between the header and the body sticks together. All you have to do:

/classes/Swift/Mime/SimpleMimeEntity.php

      if ($this->_cache->hasKey($this->_cacheKey, ‘body’))
      {
        $body = “\r\n\r\n” .$this->_cache->getString($this->_cacheKey, ‘body’);
      }
      else
      {
        $body = “\r\n\r\n” . $this->_encoder->encodeString($this->getBody(), 0,
          $this->getMaxLineLength()
          );
        $this->_cache->setString($this->_cacheKey, ‘body’, $body,
          Swift_KeyCache::MODE_WRITE
          );
      }

At the cache, I added \r\n\r\n and at the else block, I added \r\n just to be safe. That’s all!
