Contact Us works on local machine, but not on bluehost.com How can I track down why an email is not generated from my new web site when I click Contact on the Contact page?

I turned on maillog and devel. What I get is 
    maillog =>
        ... (Array, 6 elements)

Error message:


  Unable to send e-mail. Contact the site administrator if the problem persists.
Installing the SMTP module and configuring it correctly was the solution to the problem. Since I am a newbie to Drupal it seems magical that it solved the problem. I don't fully understand the logic flow of SMTP and SimpleNewsletter.

It took three different chats with bluehost before I got SMTP configured correctly.

Following are the SMTP parameters that finally worked. The email address in Home » Administration » Configuration » System - Site Information also was incorrect. I set it to admin@columbiablooms.org and everything finally worked. The admin@columbiablooms.org email address had to first be created via cpanel at bluehost. The password in the screenshots below is the one that I used when I created the email address at bluehost.







I hope all this helps another newbie ...
