I had these same issues. I needed to work with SendGrid to get my forms to work but I don't like using any third party. I do use the smtp module and debugging is fine. Settings for gmail are spelled out. I would also just check your permissions. Make sure all of admin is checked. 
I disable all logging from the beginning so I don't forget. I don't really care about it. Anyway, you may want to at least google drupal and sendgrid. Take care. Chris

Hi TIm,

Now create a file info.php right next to mail.php. Paste this:

<?php phpinfo(); ?>

Compare the two sites. See if you can find a difference that explains your symptoms.

Chris.

  I find no difference between phpinfo at localhost root and phpinfo
  at the drupal site.
  But : php is looking for sendmail - but it is postfix that is my
  mail agent.
  From both instances of phpinfo() - I see a label
  "/usr/sbin/sendmail -t -i" and a value "/usr/sbin/sendmail -t -i"

  ........

  But this is not the major problem (now you have pointed me a a
  solution for my desktop copy of my site, that's great)

  but I still have the major, major problem that from the deployed
  site at akwebsoft.com, I am getting the "Unable to send
  e-mail...." error message from an anonymous user send an email
  http://www.akwebsoft.com/node/2

  Even tho' the message is actually sent.
  This looks terrible for me. That is what needs to be resolved.

  Having that error message after someone has sent me an attempt at
  contact looks like the attempted contact has failed.

  I will worry about my localhost later ...
  thanks again

Hi Tim,

And this does look to be a drupal question. Since I'm still a relatively inexperienced Drupal developer, I'm not going to be much help, however there are people on this list that can solve your problem and have probably waited for us to get this far out of courtesy. I have helped as much as I can but there will be others that pick it up from here. Since I don't quite understand what you are trying to accomplish, I can't even ask any beneficial questions.

  Don't sell yourself short. You've been a big help! You have at
  least put me on to an issue relevant to my desktop. I think there
  may be two separate issues, so I'm going to rephrase what is
  happening at my domain at akwebsoft.com :

  I constantly see error messages :
  "Unable to send e-mail. Contact the site administrator if the
  problem persists."
  I see those error messages as admin __and__ I see them as an
  anonymous user when I send a message through the contact form.
  1)Using a PHP script as you have instructed - which uses the PHP
  mail() function works.
  2)Sending a test email from the SMTP Authentication module (which
  I installed after these error starting showing up after I updated
  to 7.24) - works.
  3)I have set all email addresses to the same and to the same as
  the domain from which it is published.
  I __suspected__ that it could be the "Logging And Alerts" module
  but when I disabled it I still got the same message.

  I at the end of my day here. I will pursue it further tomorrow.
  Again, thanks to Chris for his help and I hope to be further
  edified :)

  regards
