WordPress MU

my next request after some very clever bright spark solved the images and comments problem is....

Does anyone have any advice on why new users do not recieve email notifications when they register?

I get them but they do not.

where are the settings/script code for email notifications? is there something in .htaccess that needs to be tweaked?

I don't really want to uninstall and reinstall again (because I;ve done it a dozen times!)

anyone have any ideas?
thanks

while i'm here, is this line correct (in the .htaccess file):
RewriteRule ^wp-newblog.php$ /wp-inst/wp-newblog.php [L]

and would it be this line that might be at fault for not sending emailnotifications?

Hmm, I just tried registering a new site again on Blog-o-Matic.com and received the email notification (sent to a gmail account).

The place where the email gets mailed out to the user is in wp-inst/wp-includes/wpmu-functions.php

@mail($admin_email, __('New ' . $current_site->site_name . ' Blog').": ".stripslashes( $weblog_title ), $message, $message_headers);

So that might be one place to start investigating...

I think if you can successfully set up a new site then the wp-newblog.php .htaccess line is probably ok...

For some reason recently.. all email notification for new comments and when a user creates a new blog...they aren't emailed the password and username for that blog, and I also don't recieve a email for a new blog that was created...can someone help me with this? Where should I look?
