Anybody remember Pegasus Mail? I've used it for what must have been a decade in the 90s and early 2000s. It still exists and there were still updates in 2025! Kudos.
I'm a big fan of Pegasus Mail too! Coincidentally developed by David Harris in New Zealand, where @sundogplanets is experiencing the Thunderbird meltdown.
The only reason I'm not using Pegasus Mail is because there's no Linux build. And the source code isn't available.
