EML Quicklook plugin for Catalina

[José Antonio Galiano Sandoval]

Hi!

Catalina recently broke EML files preview. Mail has a quick look extension—MailQuickLookExtension.appex-, which is located in /System/Applications/Mail.app/Contents/PlugIns/, but it no longer works. I guess it was never Apple's intention to handle EML (as is not documented in their API), but a side effect of their former QuickLook Mail.qlgenerator.

Does anyone know an alternative? I have only found a very old plugin: MuttLight. That due to Catalina's architecture changes, doesn't work anymore.

I expect someone (Microsoft, Freron, C-Command, Devonthink, etc.) to develop a plugin in the near future. But in the mean time, the lack of a working EML Quicklook Plugin, renders Foxtrot Pro almost useless for my Horcrux's email backup (IMAP -> EML).

As a temporary alternative, I am using Apple Mail to cope with the situation. Apple's plugin works "more less" with Foxtrot Pro. But it a waste of space to have three times the same emails accounts: one in Airmail, one in Horcrux and one in Apple Mail.

Thank you very much in advanced,

Regards.

P.S.: Spotlight works correctly with Foxtrot if you install Mailmate or EagleFiler.

Catalina's Quick Look plugin for .eml / .emlx files (which is now an app extension, and no longer a "Quick Look plugin") is not "broken", however FoxTrot can lo longer use it the same way as before.

It should still be possible for your to index your eml files (as long as you have a Spotlight importer, for example those bundled with Eaglefiler or MailMate), and view them in plain text (or in the Quick Look window, with no highlighting). I don't think that using Apple Mail improves this situation?
