Thank You for answers. But: 1. How should be properly configured ssl_cipher_list? 2. Ok, removed !TLSv1 !TLSv1.1. 3. Strange thing with ssl_protocols and ssl_cipher_list, because on older server on Ubuntu 14.04 LTS, dovecot 2.2.9 and postfix 2.11.0 these two lines looks exactly this same and no errors in mail.err file and mailes works without any problem. 4. No, currently I don't use LMTP.

Cipher list which You post provide better compatibility or security than those which I currently have? On older software version these cipher list works well and not generate any errors when I run Internal PCI scan test from https://cloud.tenable.com for another server. But for new server with newer software during test I got errors in mail.err. 2017-04-27 10:00 GMT+02:00 Aki Tuomi <aki.tuomi

I haven't done this on the old, working machine. So there must be a difference between Debian 7 and 9 how open files are handled?

Changing Password Schemes

Auth process sometimes stop responding after upgrade
Hi all; I've upgraded a ring of dovecot directors from 2.2.15 to 2.2.36.

Correct settings for ssl protocols" and "ssl ciphers"
I have the following two settings in my "10-ssl.conf" file # SSL protocols to use ssl_protocols = !SSLv2 # SSL ciphers to use ssl_cipher_list = ALL:!LOW:!SSLv2:!EXP:!aNULL I have seen different configurations while Googling. I am wondering what the consensus is for the best settings for these two items. What do the developers recommend? Thanks! -- Jerry
