----------------------------+-----------------------------------------------
 WP installed in cPanel add-on domains do not send welcome messages to new
 WP users.

 Watching the exim_reject_log shows:

 F=<> rejected after DATA: there is no valid sender in any header line

 ...

 Envelope-from: <>

 ...

 F From:

 phpinfo(); confirms that the sendmail_from property has "no value."

 Adding this to .htaccess :

 php_value sendmail_from user at domain.com

 causes phpinfo() to show a valid value, but attempting to register a new
 user still shows exim refusing to send the message because there is "no
 valid sender."

 A simple PHP mail test script in the same dir works fine.
