Just to provide some balance to the feedback: I've been using FastMail for 2 years and am mostly "meh" on it. My issues are with the web interface (which is largely why I use them instead of running my own server):
- No delay send/undo send. Allegedly in the works for ages
- Very buggy editor. Randomly slows to a crawl while composing, scrolls up and down erratically
- Cannot handle very long threads very well. (since unfortunately the business world uses top replies with Html email) E.g., undo can pin a core and crash the page.
- Notifications randomly show up twice and then freeze on screen
Thanks for the feedback - I've passed that to the product team. We're busy working on the JMAP replacement web interface, which has a fair bit rewritten.
Our search is built on top of the Xapian search engine. We blogged about the underlying tech a while ago. You can sign up a free trial and have a play pretty easily.
Search works decently, but they index the whole message, including quoted text. So a search term shows up in the original message, as well as all the replies downthread.
Yeah, we're working on identifying whether something is in quoted or non-quoted text. That one is quite tricky to get 100% right, so we err on the side of matching more messages.
