Penguin Mail – open-source Rust email client for Linux with AI

Does anyone remember Sparrow?

I like the idea of a native Linux email client. The UI looks pretty good too. It's really not hard to beat thunderbird.

Calling it version 1.0 is bullshit though. It's only about a month old: https://github.com/c9dev/penguin-mail/graphs/contributors?al...

A project with the complexity of an email client cannot be considered stable in a month. There are bugs that will only show up after a year. It has a calendar after all.

1. Being released on GitHub for a month does not mean it’s a month old.

2. Seems odd to assume instability by default without evidence.

rainingmonkey•44m ago
Have you ever experienced stable-by-default?

If so, I'd love to hear a writeup!

Grombobulous•35m ago
Well, I'm trying it out and it seems stable.

It's missing some features that are dealbreakers for me, but I haven't found anything unstable yet.

This is interesting, I am doing an experimental effort with similar goals. What is your approach to testing? The bug surface of something like this is quite large. Also, do you have a plan for sandboxing?
SchemaLoad•4m ago
Sandboxing should be handled externally by something like Flatpak

Surprised to see a new (large) GTK app, especially in Rust.

Can this be compiled for other operating systems than Linux?

I was 100% interested until crossing "...with AI".
billybuckwheat•4m ago
Same here. While I'd rather not have an embedded AI chat window, is there a way to disable it?
dvno42•19m ago
Maybe I'm not the target here but an embedded chat ai window is a huge turn off to me. Having a CLI I can give my own agent to access/query the data, if I choose to do that, would have been preferred but if the target was my mother, then a chat window is probably a better option.
slipheen•14m ago
That's a very nice looking app - I like the look of it it gives me Mail.app vibes.

A mail client is always a tough thing to get right so I'm glad you're working on one

I love then idea that as the total cost (time/money/attention) of personalizing software continues to come down, more people will be able to encourage a diaspora of options, tailored to each niche.
