Several Cyrus-imap HowTos, as well as HowTos for other apps make reference to "fully qualified hostname" and "fully qualified domain". How do you manage that if your home network does not include a DNS server? I've got a few machines behind a LinkSys router, which is taking care of NAT. The ISP does DNS of course, but it doesn't see inside my little network. So, does this imply that I shouldn't try to run Cyrus-imap if I don't have my own DNS server, or that I need to trick the program in some way? If so, how? While I was going through the MTA dialog in YaST, I don't remember seeing a setting for that. In the DNS and Hostname dialog, there was a field for "Domain", and I just made up a name to fill in. Is that "legal"? Or am I going to encounter grief later, when the bogus domain conflicts with something, or fails to be resolved (because there's no DNS server...)?
