On GNU/Linux Thunderbird ist my favourite GUI mail client, offering support for a variety of standards, including e.g. CalDAV (CardDAV in Beta), OpenPGP and S/MIME.<p>Not sure whether Chat should be part of it, currently offering Google Talk, IRC, Odnoklassniki, and XMPP (Twitter finally gone). Support for Usenet News is appreciated, though I enjoy Pan.<p>On GNU/Linux I thus consider GNOME Evolution as best alternative. (Haven't looked at the KDE suite for some time with Akonadi being too heavy last time I tried it on my simple machine.) Neither Claws, Geary, Sylpheed, or others offer such broad support, although those are very nice GUI clients.<p>Further alternatives are listed in <a href="https://en.wikipedia.org/wiki/Text-based_email_client" rel="nofollow">https://en.wikipedia.org/wiki/Text-based_email_client</a>
If your company uses Office 365, these guys have a plugin that I think parses the HTML website to get your mail (and calendar!) into Thunderbird:
<a href="https://www.beonex.com/owl/" rel="nofollow">https://www.beonex.com/owl/</a><p>Just this week I gave them 10 Euros for the addon because my company refuses to enable IMAP for Office 365. I'm not affiliated with them, but I've been using the Tbird addon for a few weeks and it works perfectly. The license is per-year, though I guess that makes sense because I expect that it needs to be updated whenever the Office 365 site is updated.
I use this software every day on multiple machines (rss for work, rss & email personal). It's not without wrinkles, but at least it never feels exploitative.<p>Donated, and will consider setting up something recurring.
>[...] wholly owned by the Mozilla Foundation. Funds will be reserved for use in the Thunderbird project. [...]<p>Why doesn't Firefox have this?
I pay for the Owl extension [0] which allows me to use my university's MS Exchange account with Thunderbird. I don't understand why Mozilla don't offer this themselves though, is it too complicated to put the effort in given the size of the userbase? Or is there some reason it has to be proprietary and they're against releasing proprietary software? I really appreciate Owl, but I'd much rather just pay Mozilla directly for it.<p>0: <a href="https://www.beonex.com/owl/" rel="nofollow">https://www.beonex.com/owl/</a>
> Contributions are not tax-deductible as charitable contributions<p>Why is this? I thought the Mozilla foundation owned this and it's a non profit
Late versions of Thunderbird have integrated GPG functionality. I have tested and used this extensively and I think it's a required feature that enables most users to have excellent security in their communications.<p>For me, only this would be more than enough enough to switch to Thunderbird as my main mail client!
I donate semi-regularly. Been using Thunderbird as my primary email client (almost) since its release. The installation has hundreds of thousands of mails across many folders, and yet, it is super fast and rock solid.
I used Thunderbird for a very long time but recently stopped. Every update has made it slower, breaks a host of extensions, and the Google Calendar integration is consistently broken no matter which solution I use. I really, really want to use Thunderbird but email and calendar need to Just Work. I can't keep fixing it every time they push out an update
Thunderbird is significant tool in my daily workflows. I created multiple profiles for RSS, email, calendar, contacts and usually have multiple instances opened at once. Everything operates smoothly. I would gladly setup monthly fee but also want to have the possiblity to cancel it at any time by the end of the month. This worries me:<p>> <a href="https://give.thunderbird.net/en-US/help/" rel="nofollow">https://give.thunderbird.net/en-US/help/</a><p>How long it takes to process cancellation of recurring contribution?
I use Thunderbird, and have for a very long time. Unfortunately, the new development and progress is gradually breaking more and more extensions, making it less useful to me as time goes on.<p>Bizarrely, the donation page thinks I'm in the UK, when I'm almost as far as possible away from there.
Thunderbird is such a great program. Ever since I gave up Mutt as my default email program, I've been using all the time.<p>One of the richest guys on the planet (Zuckerberg) was using Thinderbird in a photo some time ago I think. Perhaps if he reads HN; they can get an infinite lifeline.
I wouldn't use it anyway. But I would sponsor Firefox like this.<p>However with Firefox you can only sponsor the Mozilla foundation and not the product itself.
I set up a recurring monthly contribution of $10. I've used Thunderbird for years, its my go-to client. Unfortunately these days, day job forces windows 10 and lookout. But I use it everywhere else.<p>FWIW, lookout is itself dangerous software to install/use. There are many hacks of it, including new and exciting zero-days where you don't even need to interact with the mail in any way, to have a compromise occur. It is simply not worth the risk, on any platform.<p>I've used (and paid for) both Owl and ExQuilla for office365 integration when needed. Owl was iffy ... had lots of problems. ExQuilla just worked.
Not stable enough for production. Every time I've tried to use them (3-5 times since they got started) they've lost emails and calendar events in inexplicable ways, possibly by not taking a careful enough approach when dealing with unreliable connections or full storage. The suggested solution when reporting bugs has several times been to try the latest version with no justification other than "it might be fixed now, who knows" or reset completely and spend several hours reconfiguring and re-downloading everything.<p>The least terrible solution I've found so far is GNOME Evolution, which I don't think has <i>lost</i> anything outright yet, although the UX is meh (no option for separate event start/end time zones, slow search even when all emails are cached locally, randomly requires re-signing in to Google, defaults time zone to Antarctica/McMurdo when travelling(?!?), does not seem to give any indication whether spam filtering is working or not, groups all accounts under my Google account in the Edit → Accounts view, and many more I can't remember off the top of my head).<p>Sorry to be so negative, but so far every single email client (Evolution, K-9, Mutt, Outlook, Thunderbird) has been a chore, for different reasons. Gmail/Google Calendar is the only client(s) I rate, but I'm shutting down that account slowly for obvious reasons.
After using TB for 10 years I uninstalled it half a year ago. Because of bad UI decisions and constant extension and PGP breakage. Got to a point where I froze the installation at version 68 just to be left alone. A security nightmare of course. In the end I trusted it less and less to not one day kill my e-mail archive going back 25 years. Also I still have PGP 2.6 encrypted e-mails that require IDEA/MD5 support. I know this scheme is insecure, but you can't disconnect me from my archive by no longer supporting those ancient formats.<p>Since I self-host e-mail anyway, I switched to a well-greased Roundcube web UI for desktop and FairEmail on the phone. Searching through 20 GB of mail, including text in PDF and Office formats, is more or less "Google-instant" thanks to dovecot-fts-xapian. Having everything in Maildirs for me is very pleasant.<p>For calendaring I now use Radicale and either Infcloud web UI on desktop or CalDAV-Sync on phone. Could be tighter integrated with e-mail but the old Unix ways of one tool for one job have merits, like all calendar entries are now file system objects and under Git control. Impossible now to fat-finger half the calender and having to jump through hoops to restore entries.
I dislike Mozilla's politics and don't use Firefox, but I have been using Thunderbird since at least 15 years. So yes, donated money for this project, hoping that they don't come up with some "revolutionary" UI ideas.
A better way to use email is through the browser, isn't it? I wonder what's use of an email client; especially now since the storage cost in the "cloud" have plummeted. I can't imagine backing up my 10 years worth of email locally when Fastmail on the web works well.
Use thunderbird everyday on both my machines - but they've been changing things for no good reason and breaking the UI/UX because of it. thanks but no thanks.
