Hi all Can you believe it's the end of November already? I need to setup a local mail server for a LAN, which will transfer mail to users locally, as well as on the internet. The question(s) I have has more todo with the domain(s), than the MTA itself. I'll be using Zimbra, for it's near-MS exchange features. If my domain is mydomain.co.za, how do I setup the domain for the local LAN, and do I need to worry about DYNDS if I'm going to use fetchmail to download mail from the remote mail server? Currently I have the LAN setup as mydomain.local, but then I realise that emails will be in the forum of firstname.lastname@example.org / email@example.com - so, how would pete (who's real email is actually firstname.lastname@example.org) send an email to mary (who's real email is actually email@example.com), as well as to firstname.lastname@example.org ? Does this make sense? And is it worth it to setup the local LAN on DynDNS (let's say office.mydomain.co.za), being the primary MX & then configure the ISP server to be secondary MX?
