Hello, is there any way to disallow client-initiated renegotiation at
the dovecot? I haven't found any mention of this feature within source
code as well as at the documentation.
I am asking about it because without this feature mail server is
vulnerable to a TLS renegotiation DoS attack which
I would like to offer to implement a feature to reject SSL handshakes
for a default certificate-key pair for efficiently discarding bot
requests (i.e. such requests that provide invalid/not configured
hostname or do not specify at all, like when doing request to the IP
address directly).

Thanks! Can you say where the mapping from the user part in "From" addresses to
actual mail(sub)dir goes after switching to LMTP?
Currently, I've got a `virtual_mailbox_maps` in Postfix main.cf for this
purpose. Is there something similar in Dovecot
