Configure two gmail servers in one Rails 3.2 app?

Configure two gmail servers in one Rails 3.2 app?

Is it possible to configure two gmail servers in one rails app? I did a
web search and didn't come up with anything. I would prefer not to get
involved in using postfix instead of gmail unless that is the only way.
In my production.rb file:
config.action_mailer.smtp_settings = {
address: 'smtp.gmail.com',
port: 587,
domain: 'domain1.com',
user_name: 'serv@domain1.com',
password: '************',
authentication: 'plain',
enable_starttls_auto: true }
I'd like to configure a second server for my gmail server at
serv@domain2.com. Is it possible? If yes, then how?
