    I use both Thunderbird and Evolution, sometimes Claws-Mail. Evolution is the only one that can show the real "received" date in scams I have been receiving for months. In a today's scam Evolution shows "sent date" (falsified) 14-12-2019 and "received date" 30-01-2023 (evidently true). Thunderbird and Claws-Mail show 14-12-2019 in both columns.

    As someone who is forced to use M365 at work (but ditching it at home, I let my subscription lapse) this is the closest visually to Outlook. That's important to me. The workflow is essentially identical.

    Unfortunately, only available on Linux, not on Windows, not on MacOS. Otherwise promising.
