we’re using a little bit unusual/complex certificates mostly for e-mail services. Every user has his uniqe hostname for IMAP, SMTP, etc… It is for us to be able to seamlesly migrate users between servers/clusters. Hostnames looks like this:
12345.45.imap.example.com - user #12345 12346.46.imap.example.com - user #12346
Therefore, we use certificates with following SAN names (there are 100 wildcards like that - 00-99):
*.00.imap.example.com, .., *.45.imap.example.com, ... , *.99.imap.example.com
Formely, we used StartSSL certificates and they signed such certificate for free. Now, after StartSSL is dead, we can’t get any authority to sign our certificates (for reasonable price).
Can we get such certificate from Comodo and how the pricing works? Most CAs will charge us for every SAN name but that is too expensive for us. Moreover, this certificate is basicaly still only one wildcard on single domain…
Or does anyone know about a CA that would fit our needs?
