What is the outbound IP address for e-mail server?

Good morning,

I was requested by our IT consultant to obtain your outbound IP so that they can allow this on our e-mail server.  I would like to utilize our e-mail servers for sending the form responses, and have all of our infromation for SMTP but they require the information to allow your servers to access our system's firewall.

Thank you,

Anthony
