 Sendmail will often require the from envelope which is passed as a 5
 parameter to mail as '-f from at domain.com'.

 I modified bb_mail accordingly (static should probably be configurable for
 non sendmail or windows (which uses ini settings):

 if ( !function_exists( 'bb_mail' ) ) :
 function bb_mail( $to, $subject, $message, $headers = '' ) {
         if (!is_array($headers)) {
                 $headers = trim($headers);
                 $headers = preg_split('@\r(?:\n{0,1})|\n@', $headers, -1,
 PREG_SPLIT_NO_EMPTY);
         }

         if (!count($headers) || !count(preg_grep('/^mime-version:\s/im',
 $headers)))
                 $headers[] = "MIME-Version: 1.0";

         if (!count(preg_grep('/^content-type:\s/im', $headers)))
                 $headers[] = "Content-Type: text/plain; Charset=UTF-8";

         if (!count(preg_grep('/^content-transfer-encoding:\s/im',
 $headers)))
                 $headers[] = "Content-Transfer-Encoding: 8bit";

         if (!count(preg_grep('/^from:\s/im', $headers))) {
                 if (!$from = bb_get_option('from_email'))
                         if ($uri_parsed = parse_url(bb_get_option('uri')))
                                 if ($uri_parsed['host'])
                                         $from = 'bbpress@' .
 trim(preg_replace('/^www./i', '', $uri_parsed['host']));

                 if ($from)
                         $headers[] = 'From: "' . bb_get_option('name') .
 '" <' . $from . '>';
         }
         $headers = trim(join(defined('BB_MAIL_EOL') ? BB_MAIL_EOL : "\n",
 $headers));

         return @mail($to, $subject, $message, $headers, '-f '.$from);
 }
 endif;
