similar to: socketpair failed: Too many open files on Debian 9

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?

Hi, To default dovecot.conf file I added (based on found documentation): ssl = required disable_plaintext_auth = yes #change default 'no' to 'yes' ssl_prefer_server_ciphers = yes ssl_options = no_compression ssl_dh_parameters_length = 2048 ssl_cipher_list =

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.

I have been reading up on TLS and Dovecot and came across this URL: https://www.weakdh.org/sysadmin.html which recommended these settings for Dovecot. I would like to know if they are correct? Some much documentation on the web is pure garbage. Dovecot These changes should be made in /etc/dovecot.conf Cipher Suites

Good Day, I have been following this tutorial without much luck - http://wiki2.dovecot.org/HowTo/ConvertPasswordSchemes#CA-26af2b83a43b8100522c57565773f605c21f2f27_1 It is obvious to me that I am not following the instructions correctly and need to be shown what I am misunderstanding. I have an old postfix + dovecot + Roundcube mailserver (mail.domain.Tld). Server clock is loosing time and

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 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

Hi all; I've upgraded a ring of dovecot directors from 2.2.15 to 2.2.36.

I haven't doveadm logs in /var/log/. Are they default in another place or maybe should I turn on something?
