A google search on this topic lead me to some instruction that doesn't work for me - since all
http://www.facebook.com/mobile/ are redirected to
Facebook Home site.
How can I do it now?
You can set this up easily on IFTTT.com (If This Then That).
You can use email (with or without hashtags etc.) as a trigger to post a status update to facebook. This recipe, Post to facebook from mail uses email to post a status update.
For modern browsers and smartphones Facebook prefers that you upload directly or using an App than post-by-email. So, if you use a modern browser FB will hide the address from you.
You either need to use an old browser or user agent switcher and then the instructions will work. See http://www.devineprojects.org/blog/archives/2013/07/updated-how-to-find-your-facebook-post-by-email-address-and-post-from-google/ and http://hackingbuzz.com/update-facebook-status-via-email/
