Bad Invitations, No Mass Mailing, and...

I am running Dolphin on a Godaddy shared server.  I got it running ok, but I can not get it to send invitations.  I also can not get it to send mass mailings at all.  The test message is still in queue.  Here is the error message I was getting:

>>> MAIL From:<xxx@yahoo.com> SIZE=941
<<< 553 sorry, your mail was administratively denied. (#5.7.1)
501 5.6.0 Data format error

What can I do to fix both of these problems?

Did you set up Cron Jobs during dolphin installation?

Go daddy is well known as having many probelms when hosting dolphin on shared servers, there are better options out there, Have a look a the recommended hosting from this site

Cron Jobs was set up.  I can recieve emails.  I just can't send mass mailings or the invitations to work.

I am having this problem too. I can send individual emails and users can email one another but the Mass Mail stays in the queue. Does anyone have a solution?

Use a email address from your own domain name, not from another domain like this xxx@yahoo.com

hope it helps you...
