There is no error in the server logs. I checked those particular folders on the server and they don?t seems to have anything special about them, like permission or etc. Yes, calling STATUS on those particular folders returns the status. The folders can be opened and they have emails in them so nothing special about those folders. # 2.3.5 (513208660): /etc/dovecot/dovecot.conf # OS: Linux

I am executing this command below to dovecot-2.3.5-6.cp1178.x86_64 server Notice that some status responses are missing (For folders INBOX.Archive, INBOX.spam.&-BD0EOQQ9BDkEPQ-). I wonder If this is a bug or working as expected In rfc5819 there is this: If the server runs into unexpected problems while trying to look up the STATUS information, it MAY drop the corresponding STATUS reply.

Thanks for your reply; I used the defaults, both before and after the upgrade, cf. https://wiki2.dovecot.org/Upgrading/2.3 -> Setting default changes. The new defaults broke the connection. Jan > what are your settings? > > Mine are below and they work just fine: > > ssl_cipher_list = >

Hi, I tried to migrate my dovecot 2.2 to a new server with a other storage configuration and dovecot 2.3. New (and old) Server uses mysql for user information I use the following storage settings mail_home = /storage1/vmail/%{userdb:path} mail_location =

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 =

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 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

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.

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

I haven't been able to replecate this in testing, but as soon as I start pushing production traffic to the new ring I see dozens of these in the logs: Apr 18 00:34:00 d.director.imapd.sonic.net kernel: imap-login[163107]: segfault at 10 ip 00007ff625698dd5sp 00007ffe4b77bb28 error 4 in
