HelpDesk configure second outbound email

Content

Hello experts.

We need to configure a second oubound email to the platform.
Both are redirecting to oracle native email.

1 - Is there any way to visualize and test if they are redirecting correectly?
2 - Do we need to do something extra to configure the second email?
3 - After creation we need to route it to an specific queue. but channel is not a parameter default. Do we need to create a trigger? which paraemter (before database insert?)

Thanks a lot
