Hello, We are having performance problems trying to migrate our pop/imap servers to a new version. Our old servers are 4 debian lenny with 5GB of RAM running of XenServer VMs with kernel 2.6.32-4-amd64 and dovecot 1.1.16. New servers are 4 ubuntu 12.04 with dovecot 2.1.5 running on vmware vm with 6 cores and 16GB of RAM and kernel 3.2.0-24-generic. On both server we are using nfs 3 with

Hello, Is it possible to create a custom template for XCP? Or edit an existing one? I know that I could create a VM and then exported as a template, but I would prefer to create a template like "Debian Lenny 5.0" that install debian from the network but with 64bits instead of the 32bits used by the template. -- Angel L.

Hello, I am trying to configure director as described at http://wiki2.dovecot.org/Director. I have previously tried the proxy and it worked.

Hello, I'm deploing a new email cluster using Dovecot over GFS2. Actually I'm using courier over GFS. Actually I'm testing Dovecot with these parameters: mmap_disable = yes mail_fsync = always mail_nfs_storage = yes mail_nfs_index = yes lock_method = fcntl Are they correct? RedHat GFS support mmap, so is it better to enable it or leave it disabled? The documentation suggest the

Hello everybody, We are updating our old dovecot 1.1 servers to 2.0. We have a farm os servers, with users in nfs filesystems and indexes in local fs. Mail is stored in maildir format. We don't warrant that a user is always directed to the same server, although our load balancer sends all request from one IP to the same server (during a session time with a inactivity timeout). This is

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:

Hello list, we continue our tests using Dovecot on a RHEL 6.1 Cluster Backend with GFS2, also we are using dovecot as a Director for user node persistence, everything was ok until we started stress testing the solution with imaptest, we had many deadlocks, cluster filesystems corruptions and hangs, specially in index filesystem, we have configured the backend as if they were on a NFS like setup

Hi, I am trying to update my old mails servers from dovecot 2.1.15 to 2.2.12 (freebsd ports) and upgrade to FreeBSD 10.0-P3. My mail storage are on NFS with index also. On 2.1.15 everything is ok, and in 10-mail.conf I have the good things to be added as wiki tell me (eg http://wiki2.dovecot.org/NFS). BUT, when I try a single connection like : $ telnet ::1 110 Trying ::1... Connected to

Hello, I am trying/evaluating XCP to manage our virtualization servers. Now, I have installed it in a test server and as far as I can see, it is very similar to XenServer, but I can''t manage it with XenCenter graphical console. Is there any GUI for XCP? I could connect with OpenXenCenter, but it still isn''t mature to be useful. Or do I have to use with xe commands? --

I have, but I will be happy to review it once again. On 12/18/18 2:14 PM, admin wrote: > Am Dienstag, den 18.12.2018, 14:06 -0500 schrieb Albert E.

Hello, I continue debugging my problems with my update to dovecot 2.x :-( I have dovecot 2.0.13 running in ubuntu 10.04 (lucid) x64. My users are in a ldap directory. The problem is that I have a lot of errors like: Aug 24 23:07:32 myotis28 dovecot: auth-worker(default): LDAP: Connection lost to LDAP server, reconnecting I have seen in the mail list a patch for 1.2

I have just upgraded to 1.1.8, hoping to fix these types of errors: Jan 20 10:39:27 laura deliver(xxxxxx at example.net): Broken file /srv/storage/mail/store/net/example/xx/xxxxxx/Maildir/dovecot-uidlist line 156: Invalid data: Jan 20 10:41:19 laura dovecot: POP3(yy.yy at example.at): Broken file /srv/storage/mail/store/at/example/yy.yy/Maildir/dovecot-uidlist line 2: Invalid data:

Yes, multiple imap servers using one shared nfs storage. With the same config on 2.2.13 the public interface traffic was similar to the storage interface, around 100 mbps. After we switch to 2.2.27 the storage interface traffic jumped 10 times while the public interface stayed the same. This make us thinking that something is wrong and each time a user logs in the whole Inbox content is read

Hello, We need to use iSCSI in some of our domUs. By the moment, iSCSI is not for system filesystem, but for data filesystem. I am wondering what is the best way to use it. Is it better to configure it in dom0 and then attach the device to the domU? Or is it better to configure it directly in the domU? I am thinking that if we configure it in the dom0, then we can''t share that iscsi

Hello, I have a farm of dovecot 1.1 servers (debian lenny). Mailboxes are in Maildir format. Is there any way to manually update indexes? Does it worth? I mean... Our problem is that mail is delivered via dovecot lda, but, because we have a farm of servers, we don't guarantee that mail is delivered through the same server that the user is using for his imap connection, so the imap

Hi, I need to place a maildir storage on a NFS filesystem, so I set up the config like this: mmap_disable = yes mail_nfs_storage = yes mail_nfs_index = yes mail_fsync = always lock_method = dotlock (also tried fcntl - local lockd is running, no success, now using dotlock, to be sure while debugging) The problem is that Dovecot (2.2.9/2.2.10 - the relevant code in mail-index.c is the same) logs

Hi all, I just joigned this list, so I'm sorry if this problem has already been reported. I'm running Dovecot 2.0.13 on many servers, one for POP/IMAP access, others for LDA, others for authentification only, etc. All servers are accessing a shared file system, based on MooseFS (www.moosefs.org). The FS is mounted using FUSE. All my Dovecot servers have this configuration :
