Can I use DMail from behind a firewall or proxy server?
In most circumstances yes, but there are some circumstances where you may need to rely on an ‘outside world’ SMTP server. NB: we are using the term ‘firewall’ loosely. We will mostly talk as if you are running a Proxy Server on your firewall box, rather than a router. There are two main things that you need to provide, 1. DSMTP needs some way to connect to a DNS server in order to resolve domain names to IP addresses. 2. DSMTP needs some way to connect directly to the outside world SMTP servers for non-local mail delivery.
