The best way to make this work is to use the Jetpack plugin, and enable the post-by-email feature.
That gives you an e-mail address where anything it receives is published as a blog post.
However, I found I couldn’t get it to work until I switched from ithemes security to wordfence. Apparently, it’s a known problem: ithemes security blocks xmlrpc, so post-by-email isn’t available..
Worth knowing.
It was.
Automattic.com “locked-on” to one of my JetPack-using sites, firing thousands of requests, and resulting in my hosting account getting suspended. I’ve had to remove it from ALL sites, just in case.
Not Impressed! 🙁
P.S. This happened some time ago, I’ve just realised that I hadn’t mentioned it, and I don’t want to give the impression that JetPack is working fine – it’s NOT!
