oracle solaris 11 and sendmail Issue.

Hi,

When trying to send mail to outside world ( to my gmail account)  on Solaris 11.2 client  I am getting

 

<<< 550 5.7.1 <xxx@gmail.com>... Relaying denied

 

550 5.1.1 <xxx@gmail.com>... User unknown <<< 503 5.0.0 Need RCPT (recipient).

I have one physical and 3 virtual interfaces on the system. Only change to sendmail.cf and mailhost is defined in /etc/hosts. Email is being sent through  one of the virtual interfaces and not through the physical interface. mailhost is the relay host.

 

# "Smart" relay host (may be null)

 

DSmailhost

When I down the virtual interfaces I am able to send mail to outside world ( my gmail ccount) successfully. I have used this configuration on Sol 9 and Sol 10 successfully. Any help is greatly appreciated.
