i use. for ~20 years. on variuos desktops and laptops (even on 7" eee-pc). it's somewhat wooden but it works, and no surprises. i keep few thousands mails over 2 decades, over many accounts and hierarchies of folders. Can even move things from one account to another. And most of all, it does show all mail dates as they are, even if from 1993. Unlike Apple-mail, and Android's AquaMail which only go back to 4.oct.2019 and that's it, anything older becomes of that date. i wonder, what is that 4.oct.2019 date?
