Configuring multiple SMTP hosts

Hi,

It seems to me like I used to be able to have multiple SMTP hosts and  
Balsa would choose the one that corresponded to the domain of the  
identity I'm sending the message with.

Now, for a while I was just using gmail as the SMTP host. Now I want to  
go back to sending through multiple SMTP hosts and I can't figure out  
what I'm doing wrong. No matter how I configure things, or what  
identity I use, it always sends it through gmail.

So maybe I'm remembering wrong and it doesn't pick the outgoing mail  
server based on the domain the the identity? Or maybe I'm doing  
something else wrong?

Any suggestions would be appreciated!
