Hello, I'm migrating a mail server from a centos 5 cluster architecture to a centos 6 cluster architecture. The new cluster involves faster machines then the old cluster, and a virtual machine. I use dovecot-2.0.9-5.el6.x86_64, while the old cluster uses dovecot-2.0.1-1_118.el5. Tha mail server uses mysql for the users database, and a local ldap for authentication. The storage is also much

Good morning, we have 2 Redhat Enterprise 5.7 machines, they are a cluster with some mail services in it (postfix and dovecot 2). The version of dovecot is dovecot-2.0.1-1_118.el5 (installed via rpm). >From last week we have this dovecot problem: suddenly dovecot doesn't accept any new connections, the dovecot.log file reports lines like these Mar 15 12:38:54 secchia dovecot: imap:

Hi all, we have a problem about anvil, it seems that when we have a high load the dovecot stops to work. Sometimes it is sufficient to make a dovecot reload, but sometimes we have to restart it. These are the lines related to anvil in the dovecot.log: [root at secchia ~]# grep anvil /var/log/dovecot.log | more Oct 26 11:13:55 anvil: Error: net_accept() failed: Too many open files Oct 26

Hello, I'm trying to enable hardlinks for messages sent to mutiple users. (I need this because I have mailing lists with 5000 users used many times a day). I've read that, to do this, I have to write a script that uses the /usr/local/libexec/dovecot/deliver command in this way: deliver -p <FILE> -d <USER1> -d <USER2> Of course, I enabled the "socket listen"

Hello, I have a big performance problem with a mail server using dovecot and authenticating users via ldap. The architecture of the machine is a local ldap and mysql server, they are used by dovecot for authenticating the mail users. If i use pam_sss the mail server has about 1/8 - 1/10 the performances it has if i use the pam_ldap. Even doing a 'time ls -l' on the mail tree (there are

Hi, I am trying to use dovecot replication for a two-way sync. And whatever I do, sieve-scripts won?t replicate. Mails replicate near instantaneous. When I disable the sieve-script in roundcube, the other server will create in the home of the user on the other side a folder sieve/tmp but enabling won?t create the roundcube.sieve and the symlink .dovecot.sieve -> sieve/roundcube.sieve The

Hello, I'm using dovecot 1.0.7 and have a problem with subscription files. The documentation says that this file ("subscriptions" or ".subscriptions" in the root of the maildir, I've tried both) holds the informations about the subscribed folders. I've created such a file with these lines: Trash Sent Drafts INBOX.prova INBOX.prova4 And configured a client

Hi, What is the real difference between client and process limit? According to documentation (http://wiki2.dovecot.org/Services#Service_limits): client_limit: Maximum number of simultaneous client connections. If set to 0, default_client_limit is used instead. process_limit: Maximum number of processes that can exist for this service. If set to 0, default_process_limit is used instead. But

All, I desperately need a resolution to this issue. I've asked once (about a day or two ago), but I haven't heard anything back. The only reason I press the issue is I may because without a quick resolution, I may be forced to switch over to AD (cry!). I submitted a request via Bugzilla but I saw a slightly similar problem with 3.0.20a that still hasn't been resolved, so I

What is the appropriate setting for mail_max_userip_connections ? My POP3 connections seem to be mostly 1 at a time, but my IMAP connections are often 3 per user per IP. Is this appropriate? If I change the IMAP setting to mail_max_userip_connections=1 will it break things for the user? I am trying to improve this situation: > ps auxwww | grep "imap " | wc 237 3080 22400

I'm running dovecot under runit: #!/bin/sh echo '/var/core/%p' > /proc/sys/kernel/core_pattern ulimit -n 8096 ulimit -c unlimited exec /usr/local/sbin/dovecot -F (that way, together with incron, I can automatically generate the coredumps I'm posting all the time) If I apply a patch and recompile, what is the fastest way of restarting dovecot?

Hello, When I create a ts object, I would like to get a particular value of this time serie according to the date and not the rank. However, it seems necessary to use the rank as if it were a simple vector. I would be very grateful if you could help out of this. I thank you in advance, Nicolas Ferrari

Hello, I need to call R from a java(swing) application. I manage to do it with something like : Process p = Runtime.getRuntime().exec("R --slave") OutputStreanWriter o = new OutputStreamWriter(p.getOutputStream()) o.wrote("...") ... etc but at the end no .Rdata file has been created and there are some data I don't want to reload each time (for time execution reasons).
