Hi all,
On the Essential Firewall, is there some trick to getting inbound SMTP to DNAT to an inside SMTP server? I don't care that the Astaro box can't/won't scan the emails for viruses/etc, as that's what the inside SMTP server does. I just want to be able to DNAT incoming mail connections to my SMTP server. I've tried it, and it doesn't work.
When I go into the Mail Security area of WebAdmin, it's all grayed out and says I don't have a license for mail security. Which, sure, I don't since this is the freebie version.
I've run netstat, and see that exim is bound to port 25. I'm not an exim admin, so I don't want to tackle trying to configure it. I'd be quite happy with just a simple DNAT.
Thanks for any tips and advice,
Dave
