This sounds like your adaptation:

  class IConfigInfo(Interface):
     param1, param2, ...

  configInfo = IConfigInfo(mailMessage)
  ...

The fact that the info is stored in the mail container is really of no
concern to the user of that info. This is the indirection that Jim
mentioned. While you may never need it, this approach gives you
flexbility as to how you provide IConfigInfo for mail messages.
