I know tumblr allows users to post on their blog by mail. But the email given by tumblr is not really easy to tap on a mobile phone per example.

Is there a way to post easily on tumblr using a simple mail address, or a custom one ?

(I tried email redirection with gmail, but tumblr doesn't seem to understand it).

My final idea ? During a wedding, let everybody easily post pictures by emails on tumblr.
