      $emailTo ="me@domain.com";

Your From header is incorrectly formatted. Change

$headers = "From : " . $_POST['email'];

to

$headers = "From: " . $_POST['email'];

But I'd suggest something more extensive like in the answer found here: [PHP Warning: mail(): " sendmail_from" not set in php.ini or custom "From:" header missing

And just in case you're not running Unix and encounter the smtp error after this: Failed to connect to mailserver at "localhost" port 25
