Much of the beauty of notmuch is how few assumptions it makes about your mail system. It plays well with others. For example, one deep insight of notmuch is that it *doesn't* require a custom mail store, even though a more obvious design might; in fact, it doesn't even require Maildir.
That said, I think I can see where you're coming from and I also think you're targeting some of the deficiencies of notmuch, but I also think you're overengineering the solution. As a result of notmuch's simplicity, a fully working mail setup requires a lot of moving parts besides notmuch and it can take a while for a new user to set all that up, especially if they're migrating wholesale from some external mail setup.

I and others have also suggested inotify support for notmuch before, which would make the inbound mail mechanism (be it SMTP, IMAP fetching, or whatever) completely unaware of notmuch, offer some other benefits (for example, if mail is manipulated outside notmuch via IMAP), and is highly discoverable for new users (just have notmuch setup ask if they want notmuch to monitor for new email and then fire up an inotify daemon the first time notmuch is called). > * automatic spam filtering, and tag applying; > * automatic email triggers based on tags (such as user > notifications, forwarding, etc.) Obviously the above two can be scripted, but I agree that it's unsatisfying that every user needs to roll their own delivery script. While tagging and triggering are highly personal, they're not *so* personal that everyone needs a completely custom solution. This should be more approachable. I'm not sure what the best answer here is, but I don't think it requires it requires integration with a monolithic system to do right. > * remote RPC-like access to the whole system; This is another deep insight of notmuch. It already has an awesome RPC interface: the CLI. Perhaps your actual problem is that the only supported remote transport protocol is SSH. This comes with a lot of benefits (authentication, RPC pipelining), but also a lot of baggage (a full SSH client on the client side). I've thought about this in the context of both an HTTP client and an Android client and in both cases I concluded that a simple HTTPS transport wrapped around the notmuch CLI would be the way to go. Just put the CLI arguments in a POST and send the JSON on stdout back. This is trivial to prototype as a Python CGI script, easy to build as a standalone Python server, and not especially hard to build as a robust C server. > * remote Web user interface; A good web UI would be fantastic. Based on the rest of your email, I get the impression this was a requirements driver from much of the above, especially the integrated tagging/triggering and RPC access. I've already suggested a simple solution to the RPC problem. For tagging/triggering, it's probably worth developing a solution that allows for machine-editable rules (ideally retaining user-editableness), which would make it possible to integrate filter management in to a web UI. This could be as simple as a standard delivery script that operates from some simple rule database. _______________________________________________ notmuch mailing list email@example.com http://notmuchmail.org/mailman/listinfo/notmuch
