This is the best way to monetize the extra sevices imo.

I've used Thunderbird ever since it was released as a standalone mail client and like it - although it has sometimes been a rocky experience in the past. I use it now with Fastmail as my mail provider.

One thing I might be interested in is the "contacts" side of mail. In an effort to move away from too much Google, I ditched Google Contacts and host my own CardDAV using "Radicale" [0]. This works, and I also access it via DAVx on Android.

But would a CardDAV server be something worthwhile via Thundermail? Or perhaps too small a service itself? Maybe part of their scheduling tool "Appointment"? I might prefer having this hosted elsewhere than in my house.

Is there a reason why you don’t use FastMail’s CalDav server ?

Here’s the link for anyone wanting to join the waitlist for Thundermail (the service):

I really hope this takes off well and provides some funding for the Thunderbird project too. Currently the only way to monetarily support Thunderbird is through donations (https://www.thunderbird.net/en-US/donate/ ).

> [...] support Thunderbird is through donations

I doubt donations to MZLA Technologies Corporation will reach the Thunderbird project in any meaningful way.

They'll just use it to pay their executive salaries.

Or support radical activist groups unrelated to software or technology.

Absolutely bonkers.

Great to see Thunderbird sponsoring the previous fork of Firefox Send[0]. I employed that for a short time and thoroughly enjoyed it!

I am still waiting for the announced redesign in 2022 [0] :-)

I really wish we could make uniformity a trend again. GTK has basically made it a rule that applications must do whatever the heck they want.

Then next day I'm using Inkscape on a Mac. Cmd-A on the canvas selects all elements. Cmd-A in a text field selects all elements on the canvas - and whatever text was in the field, now applies to the selection, so I start typing and instantly get garbage.

How do you Select All in a text field? Ctrl-A of course! - On the only system that has a non-broken copy/paste in the terminal.

I guess props to Thunderbird for leaving some space on the title bar to drag the window around? Do not take it for granted.

It's mostly already available, just not the default: https://blog.thunderbird.net/2023/08/make-thunderbird-yours-...

I followed the steps in that blog post and was able to mostly get there. I have a bit less padding between folders than the mock-up showed (which seems like a theme thing rather than a configuration item), and I don't have profile pictures in the message list.

It's such a shame that what was shipped there was so far off what the designs had suggested might be possible [1]

Two years ago we were told:

> We're going to build it right, and that means rewriting large pieces of our codebase. We'll ship the remaining stuff when they are ready.

I'm not sure how much more of the designs have actually been realised since then?

> No menus

> Cryptic icons with no text

> Optimised for looking good on a screenshot and not for actual user interaction

No thanks :)

Someone should really make a UI where three black lines is a skewmorphic grippy surface (like you see on steps sometimes) to move the window around, just to mess with the hamburger menu devotees.

Indeed, and 16:9 monitors are passé already.

I find this totally reasonable. I think it's a good way to fund open source. I just hope this doesn't create any perverse incentives to make self hosting harder than necessary

The Thunderbird Pro Add-on Repo [1] doesn't really make it clear - if I want to self host Appointment and Send, do I need to build the addon myself and change the endpoints? Or is there some kind of config?

> The upcoming email hosting service from Thunderbird will support IMAP, SMTP and JMAP out of the box

Is there any email hosting out there with support for JMAP?

newscracker · 2h ago
AFAIK, only Fastmail (which was the creator of JMAP).

Stalwart is a mail server program, not a live email server you can pay someone money to use.

One can of course use Stalwart to run a hosted email service.

That's fair! I didn't know they were offering that. I think it's a recent development -- it's not generally available ("contact us"), and it seems more focused at enterprise-type deployments than end-user mail that your typical Fastmail/Protonmail/etc.

But for the original question:

> Is there any email hosting out there with support for JMAP?

Stalwart really isn't a practical answer, at least yet.

Thundermail uses Stalwart

I much prefer POP, as I only send and receive emails on my desktop computer and I want to decide when I fetch new emails. Is there any way to make IMAP work more like POP?
homebrewer · 56s ago
fdm, imapsync, lots of similar alternatives. Synchronize email to your machine and then use any MUA, or even several of them, to read it from a local directory (Thunderbird also works AFAIK).

They can also remove email from the remote and keep just the local copy. Pretty much 1:1 with POP. I've been using this setup (with fdm) for probably more than a decade.

Jaxan · 1h ago
Just disable any automatic fetching. IMAP is not pushing mails to you, but the client regularly pulls.
alibrarydweller · 2h ago
Fastmail has had it for a while.

I'd hope so, they kinda made it :)

I wonder if there's a plan to prevent the spam/malware/csam issues of the previous iteration of Send. Maybe that it's a paid service will help stop that?

The @thundermail.com domain name is pretty solid. The domain name is an underrated aspect of email services IMO.

Any info on pricing for Thundermail?
mnmalst · 2h ago
I haven't seen any information on that.

I hope we'll see them set up as an Identity Provider for oAUTH/SAML/OpenID/whatever other stupid plethora of single-sign-on protocols there are. It's disappointing to always see Facebook and Google for single-sign-on providers, never a privacy-respecting OSS org.

I'm hoping this doesn't mean that "regular" Thunderbird will be phased out. :-/

Adding these additional subscription services will never compromise the features, stability or functionality our users are accustomed to in the free Thunderbird desktop and mobile applications. These services come with real costs, especially storage and bandwidth. Charging for them helps ensure that users who benefit from these tools help cover their cost, instead of donors footing the bill.

Has this been true ever?

This is about the Thundermail service - not the email client.
