This is not a L&T topic, but just to clear out the use of the 'enn eff emm'.

It works only if your post does not have any other content inside. In this case you were trying to put a link inside it, so really it wasn't an 'enn eff emm' post.

Your link was lost the moment you put 'enn eff emm' in both the subject line and the message space.

If you had not put 'enn eff emm' in them, but leave all the message space in blank and only the link in the corresponding Optional link URL and title, your post would have worked without problem.
