Hi, I am curious if Dovecot can add an empty file into a Maildir folder as soon as a mailbox has exceeded 100% capacity, and later when it detects the quota has fallen below 100% unlink the file. The idea is the Dovecot LDA would deliver the message and if this caused the mailbox to reach 100%+, add a file into the maibox say "username/Maildir/overquota". Interactions via Dovecot

Hello In my installation the disable_plaintext_auth does not appear to take effect. I can see that the value is correct using doveconf -a but it doesn't change anything. Whenever attempting to log in using IMAP I get this: * BAD [ALERT] Plaintext authentication not allowed without SSL/TLS, but your client did it anyway. If anyone was listening, the password was exposed. ls NO

Hi, After upgrading to dovecot 2.1.12, I see a lot of these errors: # 2.1.12: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-279.14.1.el6.x86_64 x86_64 CentOS release 6.3 (Final) # Filesystem: ext4 with mdbox storage Dec 10 15:21:04 mail dovecot: imap(user at example.org): Error: Cached message size smaller than expected (5010 < 8192) Dec 10 15:21:04 mail dovecot: imap(user at example.org):

hi we are using dovecot version 2.2.7 (config file given below) centos 6, qmail, vpopmail, mysql server configuration hex core processor, 16 gb ram 1 X 600 gb 15 k rpm for main drive and 2 X 2000 gb hdd for data (No raid) busy server with around 4000 email ids --- load is around 2 to 10 the issue is that SQUIRRELMAIL webmail users suddenly lose connection while they are working on the webmail.

Phillip> Users don?t create these folder. The system does based on the Phillip> configuration which is what I have to figure out. Then post your configuration details! And details on how email gets into the system and into Dovecot.

Hi, On the Dovecot wiki here http://wiki2.dovecot.org/Director it says the following: "The directors are going to connect to each others in a ring. For example if you have servers called A, B and C, director will create connections A->B, B->C and C->A" I am curious what happens in a scenario when two or more directors fail and potentially break a ring in half, do the

I just upgraded my Ubuntu server from 11.10 to 12.04.1 and that upgraded Dovecot to 2.0.19. For some reason I'm getting a lot more (5 times) disconnect in IDLE and inactivity time outs. I'm using only IMAP with two users. Both users access the server from multiple devices, phone, tablet and desktop computer. I had previously set the max_userip_connections to 20 and rarely got the

hi, one customer told us, that he has performance problem in his Thunderbird 3.1.9, while open his sent folder, which has round about 4000 mails in it, and 20k in his Inbox. For example TB, tries to sync the sent-folder list (over SSL) from the sent folder for now over 15min. In the log, I can't see any strange things, so for me, Dovecot works ok. Maybe, I should use better cache options?

Hello, I have strange problem with "losing" emails after rename mail folder(s) (via imap client: thunderbird, roundcude, etc..) How to reproduce: 1. Create some folder name, like TEST 2. Create sub-folder under TEST (like SUBTEST) Structure: TEST |--SUBTEST # doveadm mailbox list -u postmaster at testmailbox Spam Trash Sent Drafts INBOX TEST TEST/SUBTEST 3. Move (or copy)

One step further in my quest to create a replacement mail server. I now have my old mail server (2.3.19.1, macOS + MacPorts) and my new (2.3.20, Alpine Linux, Docker, apk package).

Hi, we upgraded our servers from version 2.2.13 to 2.2.27.

I have two servers pointing to an NFS mounted mail spool with dovecot.? Since I recently switched from using Dovecot v1.X, I have been experiencing high CPU use with the two Dovecot servers. I am not certain why they are not well behaved.? Here is the configuration information. This configuration is currently running at a load average of 17. /usr/sbin/dovecot -n # 2.1.15:

Thank you ! I was little concerned that the following settings are not in line with the new version: mail_nfs_index = yes mail_nfs_storage = yes mail_fsync = always mailbox_list_index = yes maildir_stat_dirs = yes mmap_disable = yes On Wed, Nov 14, 2018 at 10:19 AM Aki Tuomi <aki.tuomi at open-xchange.com> wrote: > It should eventually wind down once all the problems are fixed.

How problematic is it to have default_vsz_limit = 0 in dovecot.conf? macOS+MacPorts had this as a requirement even.
