Hi
I enabled SMTP Proxy Only because I want Astaro to scan the e-mails and then forward to my ISP SMTP Servers.
I do Not have a e-mail server on my network.
Under the Mail Routing, which is the more secure option.
1) STATIC Route -> Blackhole IP Address (A IP Address that is not used)
* Cannot leave it blank else it would disable SMTP Proxy completely.
2) Set it to MX Records.
