Hi all, Recently installed dovecot and postfix under Fedora8 and it works great. Then I installed both postfix and dovecot under VMWare Server (different machine) copying the same configuration files but changing the hostname and domain as appropriate. When testing the installation using: telnet hostname 143, I receive * OK Dovecot ready But when I telnet on port 25, I receive: Trying

Helo all, After enable auth_cache_size = 20480 and auth_cache_ttl = 0, dovecot stops working for users that are in cache. See the log bellow: 1 - POP3 session OK jan 22 14:02:59 mailserver--03 dovecot: auth(default): client in: AUTH 1 PLAIN service=pop3 lip=10.0.149.3 rip=10.0.2.2 resp=<hidden> Jan 22 14:02:59 mailserver--03 dovecot: auth(default): cache(teste2 at

Hi, I'm working on a system that have about 350K e-mail users and 100k users that uses maildrop scripts to make filters on their delivery. So, changing scripts by hand can't be a choice. I "googled" so much and I wasn't able to find any script that converts maildrop scripts to sieve. Does anyone knows where can I find it? By the way, does anyone uses dovecot-1.1-beta on a

Helo all, I'm trying to use Dovecot v1.1.beta13 lda with ldap. I made a tons of change in configurations but still can't set quota from ldap.

Hey! I have a strange condition in one of the servers that I don't where to start looking. I login to the server via SSH (cant doit any other way) and anything that I type is slow HTTP sessions timeout waiting for screen redraw. So, the server is acting "slow". server is bare metal. no virtual services. no alarms in the disk raid note: server was restarted because of power failure.

Hi all, I?m trying to create a RAID1 on a machine. I?ve already configurated BIOS (mother board, Intel, S500VSA SATA) so as to build RAID1 via hardware. However on CentOS Installer, when I reach "disk setup" screen, it shows up 2 devices (/dev/sda and /dev/sdb). Is this right (both devices being showed)? How should I proceed on this moment? If I create the

Issue: Vista reads slowly from a samba server. This appears to pop up periodically here and elsewhere. My samba.conf file has: [homes] ... vfs objects = readahead As suggested elsewhere. Writes are approximately 17-18MB/s which is acceptable. Reads are in the 8MB/s range which is appalingly slow. Using linux smbclient and windows XP clients I can read at 25+MB/s. I've enabled vfs

Hello all, I followed the wiki to configured the expire plugin on dovecot-1.1rc4 and it isn't working.

All of our Kafka clusters are fairly write-heavy. The cluster in question is our second-heaviest ? we haven?t yet upgraded the heaviest, due to the issues we?ve been experiencing in this one. Here is an iostat example from a host within the same cluster, but without the RAID check running: [root at r2k1 ~] # iostat -xdmc 1 10 Linux 3.10.0-327.13.1.el7.x86_64 (r2k1) 05/27/16 _x86_64_ (32 CPU)

Folks, At what point in iowait should I start to worry about having a bottleneck, or is this something that can't be answerd with a single integer? According to sar, after my last reboot to turn off hyperthreading as a test, at one time, I see 4.9% iowait, but then one minute later, it droped back to 0.01%, and rarely even gets to 1.0%, at least what I remember from yesterday. ?

I?ve posted this on the forums at https://www.centos.org/forums/viewtopic.php?f=47&t=57926&p=244614#p244614 - posting to the list in the hopes of getting more eyeballs on it.

Helo all, One of the users is havings problems when he tries to open .Sent folder. Only after I deleted ?dovecot-uidlist, ?dovecot.index.cache and ?dovecot.index.log the user could open the folder.

We are struggling with a strange problem. When we have some VMWare clients running (mostly MS windows clients), than the IO-write performance on the host becomes very bad. The guest os's do not do anything, just having them started, sitting at the login prompt, is enough to trigger the problem. The host has plenty of 4G of RAM, and all clients fit easily into the space. The disksystem is a

I am using postfix + dovecot 2.0.6 + mailman And others 2 serves with only postfix and dovecot writing at same storage with OCFS2. We are having problens with IOwait, and still trying to figure out why that is happen! But, problem becomes much worse when some emails are used in mailman, when it happens all 3 serves became really slow. iowait goes to 80. Does anyone have an idea how to slow

Hello, I'm writing from the otherside of the world from where my systems are, so details are coming in slow. We have a 6TB OCFS2 volume across 20 or so nodes all running OEL5.4 running ocfs2-1.4.4. The system has worked fairly well for the last 6-8 months. Something has happened over the last few weeks which has driven write performance nearly to a halt. I'm not sure how to proceed, and
