v1.6.6 troubleshooting

v1..6.6 creates a one user mail group.

go to Troubleshooting page and send a test message to that group.

Message seems to be sent OKAY, but no message ever appears.

I thought something might be up, so i used a browser to load cron.php page and got these errors:

Success: Connection Successful!

Notice: Undefined property: stdClass::$parts in /home/xxxx.org/public_html/forum/wp-content/plugins/wp-mailing-group/lib/receivemail.class.php on line 243

Notice: Undefined property: stdClass::$parts in /home/xxxx.org/public_html/forum/wp-content/plugins/wp-mailing-group/lib/receivemail.class.php on line 243

It never seems possible to send a message to the group. I will try an email to the group address (email) and see if something gets delievered.
