Multi domain SSL certificate ?

I'm going crazy looking for information about SSL certificates, I wonder if there is an SSL certificate that can secure multiple domains and subdomains of these and also serve to protect the mail (dovecot and exim) and the FTP server.



Searching the web I found the 'PositiveSSL Multi-Domain' cert offered by Namecheap, which they say is from Comodo, but on the Comodo website no reference to such certificate today (apparently existed in the past), the same in Instant SSL website.

Anyone know if there is such a certificate?

And if exist, how to install it in DirectAdmin?

And to further complicate the question, should run on a server with a single IP address.

Any information or help is welcome.



Regards,

Ramón
