Hmm. I am generally dismissive of anything about security that is undated.

All I have in my conf is ssl_min_protocol - TLSv1.1 and I don't recall ever seeing anyone set a cipher list in dovceot unless it was to try to allow older protocols.

Generally, it is better to exclude the protocols and ciphers you do not want. There is no reason to restrict yourself to a specific list of cyphers which is likely to exclude future cyphers when you forget to update it.

Certainly the recommendations made for postfix (which I am more familiar with) are unnecessary)
