How to solve this issue. Dovecot shouldn't be doing that. According to https://wiki2.dovecot.org/Authentication/Caching Data is

Hi, I've been running dovecot for many years, but now i've hit a strange problem. when retrieving imap there is sometimes in 1 of 4 imap requests a 4sec latency. * notes: - connected directly to the backends this latency disappears - removing a director from the loadbalancer(lvs) so i'm the only connected to the director this latency disappears too I would appreciate some feedback

I've thought about doing this someday (adding snapshots to a user's namespace) but never got around to doing it. Snapshots get rotated (e.g. hourly.1 -> hourly.2 -> etc.)

Hi, today we have exceprienced really major difficulties with our proxy backend servers. Everything started after enabling auth cache: auth_cache_size = 100M auth_cache_verify_password_with_worker = yes auth_cache_ttl = 1 hour auth_cache_negative_ttl = 1 hour Soon after we start receiving lots of calls from our customers about 'missing all e-mail messages'. This was in errors logs on

Hi, Trying to keep abusive/buggy IMAP clients at bay on a number of Dovecot proxy servers, I've reconfigured them to use "mail_max_userip_connections = 50" in the "protocol imap" section, followed by restarting Dovecot. Yet, I'm still seeing 160+ established connections from a single IP address for the same email account. Am I missing anything? # 2.2.27

Edit: When using win8, then logs started appear in dovecot.rawlog. But as win10 gives error in ssl level, before user authentication, then no debug logs will be written into user dovecot.rawlog folder. So how to debug this ssl issue?

Hello, I'm migrating many accounts to a new server with vpopmail 5.4.33 and dovecot 2.0.11. I've already vpopmail 5.4.32 and dovecot 1.2.16 on others servers running without problems. With dovecot 2.0.11 my lastauth file is not updated. This file usually is update on any access (smtp, pop3, imap) with the client's IP, for every mailbox. Now it's updated only when a client

Hi, mail_max_userip_connections is only enforced at the backend level. The setting has no effect on proxy. If you want to force the limit then you can only do it in the backend.

# 2.3.4.1 (f79e8e7e4): /etc/dovecot/dovecot.conf Hello, we're using mail on NFS and the indexes on localdisk, with a director setup. (18K+ users) now to get more performance i thought to use the ITERINDEX option. however this has the side-effect on some mailboxes that it doesn't show the subfolders under INBOX. they seem 'disappeared'. Removing the ITERINDEX option fixes this

Hi all, I have observed with my Dovecot setup that unique failed logins cause legitimate correct logins to be slowed. I am running two servers, each with two Dovecot instances, a Proxy with Director, and a backend Dovecot. I suspect that the backend instance is throttling connections from the same IP, and because I am running a Proxy, the backend will only see either of the two server IPs. I

I ran into two issues trying to upgrade our dovecot installation (Solaris 10). 1) Does not compile with OpenSSL 0.9.7 Not a big deal, as I was able to successfully against OpenSSL 0.9.8, but does dovecot require OpenSSL >= 0.9.8 now? libtool: compile: gcc -DHAVE_CONFIG_H -I. -I../.. -I../../src/lib -I../../src/lib-test -std=gnu99 -O3 -fomit-frame-pointer -mcpu=ultrasparc -Wall -W

Hi, since migration to Dovecot 2.2 I have troubles with lazy_expunge as soon as a user shares a folder. The user the folder is shared to cannot login anymore, dovecot logs Fatal: lazy_expunge: Unknown namespace: '.EXPUNGED/' - When no folder is shared lazy_expunge is working fine, deleted mails are moved to the expunged namespace and can be recovered without any problems. - Sharing

Seems this 2.2.24 is the last win10 compatible version (as my testserver doesn't have win10 users and thunderbird works well), any never version gives an error. However I didn't find any hint from http://www.dovecot.org/list/dovecot-news/2016-July/000324.html etc. --

Hi, I've been trying to build a password forwarding proxy to Gmail without success... The SSL connection to Dovecot is happening no problem (as far as I can tell), but for some reason the conversation between Dovecot and Gmail is getting timed out. I know this is supposed to be simple... :-( But could somebody please give me some help by pointing what I'm not doing right? No matter

Hi All, Is there any specific details we can extract from dovecots authentication cache (besides Authentication cache hits)? Reason i am asking is because we had a mysql user account which was returning a unknown user account. Fixing the one value in the sql result didnt have any affect and Dovecot was still returning an auth failure for the user after 24 hours had elapsed, even though
