Default Cant send email new install ispconfig 3 on ubuntu 11.10

First, thank you for ISPCONFIG. I have been using it for a couple of years. I did a fresh server install on 11.10 ubuntu and I can receive mail but cant send it. I have no problem with my other server 11.04 ubuntu. I can telnet my domain and port 25 so my isp is not blocking port 25.

The mail log gives me this when I try to send. " warning: hostname verification failed: Name or service not known"

I get this message when anyone tries to send mail in the mail log but with their ip. The computer just tells me that the username and password is wrong for smtp.
