I want to use on-premise SMTP server to send emails (to report the outcome of the process execution) using Boomi Mail Connector from a process running in Cloud Atom. The SMTP server is behind client's firewall and cannot be accessed from outside (not open to internet). The client security allows SMTP server connection through IPSEC Tunnelling (VPN).
Is it possible to set up IPSEC Tunnelling using Boomi Cloud Atom (we use SF Cloud)? I am using Boomi Mail connector to send emails.
If not, are there any other secure ways to achieve this?
