[OT] .eml format

[Richmond Mathewson]

Microsoft Entourage or
Outlook Express. This is just fine and dandy if you have bought into the 
Microsoft "thang"; but we
haven't.

opened the .eml format document entirely smoothly (although an internet 
search only
seemed to yield leads to commercial software that  could do the job).
