How to export an email from Mail application? I would like to export one particular email to .eml , so I can save it on my disk and then manually attach to another message.

I am aware of those two options:


export whole mailbox
forward email as attachment


Neither of them meet my requirements, and this seems like really basic functionality.
Actually that functionality is beyond simple. Drag the email from the Mail.app window to the desktop. When you reach the desktop the pointer then contains acircular green "+"

Drop the email there and you now have a single message as an .eml file
