Users are willing to send original email (.eml) as attachments, instead of replying.
Currently, emails can be saved from Notes Client, but not from Verse. iNotes has a really techy way to do it, which is Show Full MIME, copy contents and then paste in an empty text file and then save it as an .eml file, but Verse does not offer that.
Gmail offers the Download email feature.
OWA also offers the Download email feature.
From the security point of view, we also require to download original email in order to get the full headers and properly handle it
So, Download email should indeed be added to Verse.
