Email notifications not being sent

Reference this discussion:

http://stackideas.com/forums/email-notification-of-new-blogs-not-working

which is now locked. There were several issues, including EasyBlog parameter settings, which Nick kindly helped with.

At this point, the parameters are set correctly, the mail is being generated (thanks to Nick for showing me how to verify that), but the cron job is not working.

The cron job command is the following:
wget -O - -t 1 "http://cal-sailing.org/index.php?option=com_easyblog&task=cron";

When it runs, or when I run the command from a shell, I get the following error:

calsaili@serv01 [~/public_html]# wget -O - -t 1 "http://cal-sailing.org/index.php?option=com_easyblog&task=cron";;echo "Easyblog job completed $(date)"

I am able to enter the following in a browser, and it all works:
http://cal-sailing.org/index.php?option=com_easyblog&task=cron

I entered a ticket with my web hosting provider, and they told me that EasyBlog was returning the 409 error, and so I should contact you.

I turned .htaccess off to see if that was the problem, and I got the same error.

TIA.
