title: What is the standard way when creating a .eml file from emails with attachment?
body: <p>Have written a C++ code which converts an email to &quot;.eml&quot; file. It will be similar to the Gmail feature when we click on an email and select &quot;Show Original&quot;.</p>
  <p>What is the correct way when we are creating .eml files to be consumed by other servers. Should we add the attachment data into it OR it should be a separate file?</p>
