We are hosting providers using Zimbra Professional.
We currently have one ssl sertificate for our own domain in zimbra.
Some our customers have requested own ssl sertificate for their mail.domain.fi. I have tryed to find solution for this and if i understood correctly zimbra doesn't support multiple certificates to be installed for server.
Putting zimbra inside Iframe is something i would considering "cheat" and doesn't give that security what is usually wanted from ssl.
We have looked for multi-domain sertificates as one option but they are quite expensive.
We have single-server installation, what would you consider best/easiest to deploy/cheapest solution for this problem?
