Outgoing mials from group email account

Hi. I have a group created with 2 members. I recibe emails to the group with out any problems. But a 3rd party system provider need to configure the group account just to send emials in our name.

Can I use the group email as outgoing (smtp) account? In this case how I do to set up the SMTP, witch pass Iill submit?

Tks!
