While switching from the Swift Mailer to the Symfony Mailer I encounter a bug Symfony\Component\Mime\Exception\InvalidArgumentException.
Steps to reproduce:

  1. I have created an email with an attachment that is a remote file and saw An exception has been thrown during the rendering of a template.
  2. Also when I have visited tab E-mails in the Symfony Profiler, saw the same Symfony Exception page

DataPart can't be created from url, even if fopen can open url.
Apparently, before Symfony 4.4.11 this worked with URLs. At least in the context of email with attachments.
PHP doesn't support rewind on non-local streams, so calling multiple times method getBody from TextPart would return an empty string. So in another context, it worked partially.

Additional notes:

  1. Network example based on this
  2. Base64Encoder chunk split base64 encoded string so I only check the first line
