I would setup a fourth VM with OPNsense doing the NAT between your public IP and the other VMs with private IPs and then port-forward SQL ports to SQL VM, port 80/443 to webserver VM, pop3/imap/smtp ports to mailserver VM.

And OPNsense could also optionally work as intrusion detection/prevention, recursive DNS server, DHCP server, VPN server for more secure management, reverse proxy, ...
