Hi
sme7admin won't alert you for OpenVPN connections, only the builtin PPTP.
If you want to have an email each time a client connects, it's quite easy. Create a custom-template for the config file /etc/openvpn/bridge/openvpn.conf and add a --client-connect directive which call a simple script, which will send the mail. man openvpn for more informations on this directive. You can even send who is connecting and from where using some environment variables. You can also do the same for --client-disconnect to have an email sent when clients disconnect.
Cheers, Daniel
