Greetings,
Thanks again for your reply.
Here is what I have tried
1. I have used the facebook email and sent an email from my Google Mail account. No problem, the update appears on my facebook page.
2. I replaced the email in the plugin settings with my own email. Here is the post that I entered

and here is the email I received:

It would seem to me that there is a problem in the way the server is sending the email.
Any suggestions?
