SNI via lookup?

Hello,

How (if at all) might I configure a Dovecot server to read its SNI configuration dynamically?

Right now I’ve got thousands of domains all served from a quite-large static config file that has to be rebuilt every time a domain is added or removed. It would be much simpler if there were a way to make Dovecot call out to some external service to fetch a given domain’s certificate.

Thank you in advance!

cheers, -Felipe Gasper
