Is Diffie-Hellman needed on a modern new dovecot setup? ssl_dh is empty by default. Both ssl_cert and ssl_key on my setup are pointing to let's encrypt certs.
However i see Diffie-Hellman related warnings in logs: dovecot[1073]: imap-login: Error: Diffie-Hellman key exchange requested, but no DH parameters provided. Set ssl_dh=</path/to/dh.pem Am i causing issues for some users by not setting up ssl_dh or is this something being phased out?
