Question :

I had a complaint about the amount of spam I was getting from one particular sender, so our system administrator asked me to send him samples of the eMails in EML-format so he can have a look into the eMail-headers and adjust the spam-filter.

But how do I export eMail messages as EML-files ?

Answer :

EML is short for eMail ; an .eml-file is the typical way for macOS (and MacOSX) to store individual eMails that are not in your mailboxes.

The easiest way to export an eMail message from Mail.app to an EML-file is to Drag&Drop :

• in Mail.app, select the one eMail that you would like to export
• click on the eMail and drag it out of your Mail.app onto your Desktop (simply put : “Drag&Drop”)
• now, on your Desktop, the eMail will be automatically be saved as an EML-file
• you can double check this by right-clicking on the eMail-file on the Desktop and choosing Get Info ; at ‘Kind:’ it will be listed as ‘Email message’, and at ‘Name & Extension:’ it will be listed with the ‘.eml’-file extension if you uncheck “Hide Extension”

Then you can share the eMail as an attachment in another eMail or put it on a USB-stick or upload it to your system administrator or whatever you like.

That’s it 😉

enjoy !
