I haven't doveadm logs in /var/log/. Are they default in another place or maybe should I turn on something? My config (default passdb block and auth_mechanisms, nothing more changed): root at vps342401:/etc/dovecot# doveconf -n # 2.2.9: /etc/dovecot/dovecot.conf # OS: Linux 3.13.0-100-generic x86_64 Ubuntu 14.04.5 LTS auth_mechanisms = plain login listen = *,[::] log_timestamp =

Is there any strange thing in these config lines? 2017-02-01 9:40 GMT+01:00 Aki Tuomi <aki.tuomi at dovecot.fi>: > doveadm log errors can be helpful too > > > On 01.02.2017 10:25, Poliman - Serwis wrote: > > I can check each logs, I have root privileges. > > > > 2017-02-01 9:04 GMT+01:00 Aki Tuomi <aki.tuomi at dovecot.fi>: > > > >> Can

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.

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 =

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 set icecast.xmp: <listen-socket> <port>8000</port> </listen-socket> <listen-socket> <port>8443</port> <ssl>1</ssl> </listen-socket> 8000 work, 8443 not work. If set ssl to port 8000 not work nothing V V sob., 27. jun. 2020 ob 18:13 je oseba Paul Martin <pm at nowster.me.uk> napisala:

Default it was: "auth_mechanisms = plain login" and I added cram-md5. After restart all work perfectly. But after I added: driver = passwd-file args = scheme=cram-md5 /etc/dovecot/cram-md5.pwd I can't set default lines because I got error. Please tell me which lines should be changed to resolve this issue. Should I remove "login" from auth_mechanism

Hi @all, after re-installing one of my two frontends/proxy-servers I get the following error messages after some time (sometimes after 1h, sometimes after 24h): 11:23:55 imap-login: Error: socketpair() failed: Too many open files 11:23:55 imap-login: Error: socketpair() failed: Too many open files 11:23:56 imap-login: Error: socketpair() failed: Too many open files 11:23:56 imap-login: Error:

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?

I always restart dovecot after change config. ;) Sure, I commented out added two lines by me, restarted dovecot and here it is: # 2.2.9: /etc/dovecot/dovecot.conf # OS: Linux 3.13.0-100-generic x86_64 Ubuntu 14.04.5 LTS auth_mechanisms = plain login cram-md5 listen = *,[::] log_timestamp = "%Y-%m-%d %H:%M:%S " mail_max_userip_connections = 100 mail_plugins = " quota"

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

When I used backup copy of the dovecot.conf file I have this same error. So I think that maybe something was written to database? I really would point out that I only added passdb { driver = passwd-file args = scheme=cram-md5 /etc/dovecot/cram-md5.pwd } and comment out from above block default lines #args = /etc/dovecot/dovecot-sql.conf #driver = sql And in auth_mechanisms add line

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
