"Used Thunderbird + Lightning for many years (8+); switched to Evolution one year ago. It works with some bugs as Thunderbird works with some bugs. 50/50 toss up by my reckoning. My one issue with Evolution is installation: Using two machines and three installs, when installed from Synaptic or Software Manager it would NEVER work giving a broken pipe error trying to connect to Yahoo Mail. When installed from the Flatpak version it works as advertised. At this time, I plan to continue using Evolution."
