Fastmail is nice. I'd love to host my email on my home server, but from what I can tell, to send SMTP I either need to get a static IP (costly / impossible) or use some smpt routing service, in which case not that much is gained from self-hosting.

I wrote about how I use Google-alternatives here: https://news.ycombinator.com/item?id=5718126 An addendum to that, since the article mentioned Music and OwnCloud: I use Subsonic to stream my music collection, the Android app is very nice in how it caches so I always feel like I have full access to my complete collection without getting huge mobile data bills; I don't think OwnCloud's music app can match Subsonic quite yet.
