Sad news. The longstanding email client Postbox has been acquired and shut down by eM Client, described by the announcement as "a leading email platform for Windows and macOS that combines email, calendars, tasks, contacts, notes, and chat into a single, easy-to-use application."

[...]

On the other side of the equation, I've never heard of any Mac users relying on eM Client, despite its cross-platform status. I was going to say that I'd never heard of it at all, but searching my email reveals that I tested it briefly in February 2022. I suspect it's a Windows app that has been clumsily ported to macOS. (Ironically, I was just encouraged by a PR person to look at Mailbird, another Windows email client that just released a version that runs on the Mac but bears little resemblance to a true Mac app.) eM Client gained iOS and Android clients only this year.

There's a migration guide. I know that eM Client has some dedicated fans, and I've received requests over the years for SpamSieve to work with it. Unfortunately, eM Client does not support plug-ins or have any meaningful AppleScript support. Some customers are running Apple Mail in the background to filter their mail with SpamSieve. They can correct any mistakes from within eM Client by moving messages to special TrainSpam and TrainGood mailboxes. I'm open to working with eM Client if they would like to add direct integration.
