Adding a cache to the Exim server would be rather non-trivial,
because the Exim SMTP server is stateless. IIRC Each connection
is handled by a separate process. It still seems to me that the
problem is best solved by making it trivial to deploy the desired
nameserver configuration, without changing Exim.
As for me, I don't use Exim, I mostly just lurk on this and the
users list, and respond just to questions about TLS and DANE, but
DNS is also rather close to my area of expertise, so I decided to
delurk in this thread.
The real Exim developers will decide what they want to do with or
without my opinion...
