I've multidomain Zimbra 7.1.4 server with single IP address (virtual hosts). Every domain has its own SSL certificate, so if I'm opening webmail client its using one of the certificate depending on address given in web browser.

When I'm trying to use mail client (like Thunderbird, Outlook) it gives me a "wrong certificate" message, because for every virtual hosts server sends his main certificate instead of separate certificate.

Is it possible to serve speparate certificate for every host for SMTP auth?
I've found this instruction, but It's about many IP addresses, and I've only one: Multiple SSL Virtual Hosts 6.0 - Zimbra :: Wiki
