confused with ssl settings and some error - need help
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?

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.

Public Folder Problems
Hi, I've been trying to get a Public Folder namespace working, so far without any luck. I've tried in my home folder, outside my home folder, with and without acl. I can see the namespace (PUBLIC) in Roundcube, but that's as far as I get. I've put a .FirstFolder under the location, but it never appears. I've added dirs cur, new, and tmp but no difference.

I have configured the dovecot-master-users [2] file with the appropriate permissions. When I try to access, for example with roundcube, through user at mydomain.com*my_master_user at not-exist.com I see in the
