Translations:Complete Virtual Mail Server/SSL Certificates/7/en

There are a few issues that arise when using multiple domains on a single IP. Apache has solved this issue using SNI that makes it possible to have several certificates on a single IP. Both the browser and the server need to support this however. IMAP (and POP3) nor SMTP really support this. The only real way to support multiple hosts on a single IP is have a certificate, that covers all domains. Not pretty but can work.
