Hello everyone

Ubuntu 8.04 64bit Rails 2.3.2

I have multiple IP addresses on a server, with an alias setup to handle  
it

eth0:0 IP 1.1.1.2  
eth0 IP 1.1.1.1

We run one app on one IP, and the other on the other IP(ssl  
restrictions)

The app on 1.1.1.1 is allowed to send mail through our gateway.

What’s happening is that our Gateway is blocking emails from the app  
that is setup to run on 1.1.1.1 saying that the email came from 1.1.1.2

Is there a way that I can tell the ActionMailer to send from 1.1.1.1?

Any help, greatly appreciated.
