Dear Sir, I'm having problems with the implementation of prefetch userdb. Following the directives from the site (http://wiki2.dovecot.org/UserDatabase/Prefetch), I am unable to avoid the second search to the user backend (ldap). Could give me any advice or tips to achieve my goal? Thanks a lot, Hector M. Jacas My ldap has the following structure: search base:

We are unfortunately still seeing a lot of these errors once the machine reaches a high number of concurrent users/logins (just below 20k simultaneous IMAP connections on a powerful 24 core machine with 128GB RAM): 2020-01-14T09:18:58.661349+01:00 dovecot: imap-login: Warning: net_connect_unix(imap) succeeded only after retrying - took 140330 us 2020-01-14T09:18:58.854692+01:00 dovecot:

Hello, I have configured director in front of dovecot imap/pop/lmtp servers. When I need to manipulate a user mailbox, I use doveadm commands at director server's, with -S option. But some commands return exit code 139 when command returns more than 40 entries (I think). For example, the command: sudo doveadm fetch -u amateo hdr mailbox Trash HEADER Subject "nyctalus11/"

Hello, We have two (load balanced) director servers in front of 4 dovecot backend servers. Yesterday we had a problem at backend servers for some users (our SSO was down, so IMAP users couldn't authenticate) and this triggered a problem in director servers where almost nobody could open a new session. In our director's logs I could see errors like this: Mar 20 20:52:47 myotis41

Hi All, I need to import mailboxes into my Director NFS setup via one of my director proxy's as doing a direct dsync to the backend mailstores appears to giving me NFS locking issues. It looks like it may be possible to do this using doveadm listeners. I have setup doveadm listeners on a test proxy and backend mailstore. I am not sure how to make the dsync proxy through to the backend

Hello, I'm running dovecot 2.1.9 and I'm trying to configure shared folders. So, as described at http://wiki2.dovecot.org/SharedMailboxes/Shared I have configured a namespace like this: namespace { type = shared separator = / prefix = shared/%%u/ location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u subscriptions = no list = yes } In one user (user1) I have configured ACLs

Hi all, I hope it's okay to bump this once after four months. In the meantime we updated to 2.2.26.0 and our problem still persists: After unsubscribing from a shared mailbox, the subscription instantly re-appears. A pcap was attached to my original mail, in case it has something to do with dsync: http://dovecot.org/pipermail/dovecot/2016-September/105419.html Is anyone on this mailing list

Hi. I'm setting up a new IMAPS server. Mail users don't have login access to the box but will each have unique UNIX-style UIDs: no back-end database or LDAP thing. So far. Their mail will get delivered to UNIX-style mailboxes in /var/mail/%u (where %u is the UNIX username obviously). Their IMAP folders will go in /var/imap/%u. These will contain subfolders once everyone migrates to the new

Here's a few tips: 1. I assume that's a 2U format -24 bays.?You only have 1 raid card for all 24 disks ? Granted you only have 16, but usually you should assign 1 card per 8 drives. In our standard 2U chassis we have 3 hba's per 8 drives. Your backplane should support that. 2. Add more drives 3. Get a pci nvme ssd card and move the indexes/control/sieve files there.? On Monday,

Hi, all I've recently upgraded to 2.1.16 and found my self in deep .... There are 4 accounts in my setup that need to be accessed simultaneously by 5-6 PCs on a local lan. The thing is if a user A updates, deletes, flags mail messages in the imap folders the changes don't get propagated to the other mail clients. To state this clearly, PC (A) thunderbird has an account SALES, Maildir

Hi erveryone! I'm trying to run Postix and Dovecot on a Mac OS X, but somehow, it doesn't work. I probably messed up the privileges or something else. Hopefully someone of you, can help me figure it out. So far, Postfix is delivering the mail into ~/Maildir.

Hi list, I've just set up a 2.1.7 server, and have migrated a couple of accounts across from a 2.0.15 server, keeping the old configs. I have a strange problem on the new box in that altmove just doesn't work. I have my main storage under /home/email, indexes under /home/indexes and ALT under /home/email_archive.

Hi, I have a fedora28 system with dovecot-2.3.5 and I'm trying to figure out why I'm increasingly receiving duplicate emails. The message IDs are exactly the same. It's always two of the same messages. I don't think it's ever occurred in the inbox. It doesn't happen with every message or seemingly in every folder. I've read about dovecot deduplicate, but of course I
