I got it working with the help of a couple of IT guys, however it works internitenly. the fields are
SMTP Mail Server Address mail.skyjacker.com
User Mail Address [email protected]
SMTP Mail Server ID [email protected]
SMTP Mail Server Password ********
SMTP Mail Senders Address [email protected]

Tech support said they didn't know why it works intermitenly but I could load some software from sharkwire.com to be able to trouble shoot.... of course if it is a MBX issue there isn't much you can do.
