Installing Drupal

Ive been testing adding new users to a test installation of Drupal I have set up. When I use a mail address on the local box, all is well. When I use any other address, a yahoo address for instance, I get this bounced back:

Invalid or missing envelope FROM address.

I have a valid email address setup in the site configuration. Anyone seen this before? Any help?

Thanks

does anybody know why i'm getting a function.implode error when using the bluemarine theme? it doesn't do this with any of the other themes.

warning: implode() [function.implode]: Bad arguments. in /home/notbush/public_html/includes/theme.inc on line 35.

i was messing around with some installed themes (just looking at them, really) and suddenly my drupal site returns this, in its entirety:

how can i get back in? is this a theme issue or something else?

for what it's worth, i'm using galeon on RH8 beta 3.. when i signed up here for an account and logged in, i got the same thing.

i've killed the appropriate cookies.

I don't know if I'm doing something wrong or if it just takes a while, but my new Drupal powered site is not showing up on the Drupal site listings. I have Drupal enabled, all my fields filled out, my Drupal XML-RPC server setting is pointing to http://www.drupal.org/xmlrpc.php, and I have a cronjob running to ping the cron.php page every hour. Any help would be appreciated, and any feedback on the site is welcomed as well.

Thanks in advance for the help.

A test installation of drupal in a user directory of my OS X at first suffered from a wrong magic_quotes_gpc setting.

I attempted to resolve this by allowing the .htaccess file to override the basic settings but this had the effect of preventing access to Drupal.

Further inspection revealed that all access to the directory was barred

I've been searching for a while now and can't find an answer. I want to create a site page and am wondering if include_once will work to bring in a PHP page. Do I need to have the file on the root or can it be in a directory? Also, do I have the code correct:
<?php include_once("filename.php"); ?>
or
<?php include_once 'filename.php'; ?>
or
something else?
