Alternatives to Posterous?

My blog has been on Posterous for some years now and it's been awesome. The best thing about it is that you just email a bunch of stuff, with whatever attachments in whatever format are relevant, and they just work.

Sadly they're shutting down following their talent acquisition by Twitter. That's a real shame. Now I have to find an alternative.

Requirements:
  • Hosted. I'm not going to maintain a server just for blogging thanks.
  • Allows custom JS. I'm always testing out new analytics tools on my own sites.
  • Post through email
Squarespace is lovely but pretty expensive for what I need, unless I can consolidate all three sites into one platform while keeping the domains (waiting on their ticket response).

I had high hopes for Markdown-based blog tools like Jekyll, but I find them a bit clunky. Posterous has got me used to a really easy blogging workflow that works well for me.

Any suggestions? I'm happy to pay.

If you find something - particularly another meta-posting service, please let me know. While I liked posterous for its interface and ease of use, it's biggest advantage, for me, was as a post-distributor functionality that allowed me to automate posting across multiple platforms. Fortunately, I don't need to export my Posterous because all my content is already also on Tumblr, BlogSpot, Wordpress, etc.
I keep looking too and am finding nothing that has the same features - except maybe Posthaven ;-)
Tumblr is the new age blogging platform, it is more twitter like.

Moving to Tumblr can be tricky as its more simplified. You can use tools like http://justmigrate.com to move your blog to tumblr.
