If you have one host with one IP, I hope you have one mail server since only one process can listen on port 25 on a single IP. Any normal mail server can host mail for many domains. My little 1U server handles 140 different mail domains and it certainly isn't listening on 140 IPs. >> Also, why the wildcard CNAME record?

You can have a *.example.com certificate and set up your DNS and web server for specific names foo.example.com and bar.example.com and however many others you actually use. Unless you have special coding in your web sites to handle arbitrary random domain names, you will probably give people a lot of mysterious 404 pages when they try names you haven't configured. >Good point, I'll change to "?all" instead. Right, -all is asking for trouble.
