Actually, that’s a big annoyance with Apache, that the configuration expects every virtual host to have the same SSL certificate. So if your vhost has 5 domains, you need a single certificate with 5 domains. Bleh. Dovecot does it much better: you just feed it a hash table of domains and key/certificate files.
in case of a database-server (as also for a mailserver where this crazy idea comes too each year) you have *one* dmaned server, your username and your password - *why* do you need different hostnames for it?
As you imply, the greatest use case for SNI is for web hosting. Mail is less useful but still relevant: domain owners want to brand all of their services with their domain name. If I’m setting up “felipes-stuff.com” and have employees go to “hals-hosting.net” for mail, that’s not as “branded” of an experience as if everything used the same domain. Database access is similar. There is still a use case for SNI here, even if it’s not the most apparent one. -FG
