Hello All, I've been studying dovecot for replacing my company's current system and I got a little worried about an aspect of the dovecot's design. I was surprised that dovecot doesn't use prefork for its mail processes, forking a new processes for each new client connection. Talking in the #dovecot channel I was gave a scenario of a system supporting ~40k users with 4 servers

Hello there, I have a "subscriptions" file that is *not* ended with a line break (created by another system). When I do a "lsub "" "*"" the last mailbox name is not listed. Debugging a little showed that it looks like i_stream_next_line() is not returning the last line if it doesn't end with a line break. Is this a bug? btw, i'm using version

Hello, Is it possible to configure the filename format in dovecot? For example, to change from "unique,W=size:2,FLAGS" to "unique,size.hostname:2,FLAGS_unique2"? Thanks in advance.

Hello there, I've being reading the zlib plugin and the dovecot code and I can't see a way of extending the plugin for writing compressed mails instead of just reading it. Any clue? Tks in advance, gpg

Hello there, I have a client connecting to dovecot and comunicating like this: * OK Dovecot ready. * AUTHENTICATE MYAUTH + base64 challange base64_response {NNN} * NO Invalid base64 data in continued response The problem is that dovecot seems to reject the response because of the {NNN} in the end of the string. If I remove the {NNN} it authenticates just fine. Any idea of whether it's

Hello there, I failed in finding the answer in the wiki so i'm asking it here. In average, how much the dovecot's indexes increase the usage of storage, compared to a standard maildir mailbox? I believe it would be a function of the number of messages instead of the message's size. Is there a known aproximated function for that? Thank you. gpg

Hey, Anyone tried before, is it successful? Also, Is it possible to use the CPU VT inside Xen if it is running inside VirtualBox? I want to setup such env. for testing purpose. Thanks. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hi, Our dovecot setup consists of two hosts running dovecot-1.0.beta9 with Maildir/indices stored on NFS(noac,actimeo=0 used). I am seeing these messages at times - but no real problems on the client side. Is this something to worry about? dovecot: Oct 17 10:33:31 Error: IMAP(user): Corrupted index cache file mailstore/user/Maildir/.mail.incoming/dovecot.index.cache: invalid record size

We are seeing some poor performance recently that is focused around users with large mailboxes (100,000 message /INBOX, 80,000 message subfolders, etc). The performance problem manifests as very high system% utilization - basically iowait for NFS. There are two imap servers with plenty of horsepower/memory/etc. They are connected to a 3050c cluster via gig-e. Here are the mount options:

Hi, well i mounted the OCFS drive over nfs, but it seems to have problems with it, because the NFS does not detect changes (if I add or delete files) the nfs shares still shows the old status. If i delete a file on the OCFS volume, and i am doing a "ls" on one of the nfs clients, it says for every file which was on the ocfs, "no such file or directory". Did I miss

Timo (and anyone else who feels like chiming in), I was just wondering if you'd be able to tell me if the amount of corruption I see on a daily basis is what you consider "average" for our current setup and traffic. Now that we are no longer experiencing any core dumps with the latest patches since our migration from courier two months ago, I'd like to know what is expected

Hi, I had to review a samba setup recently where people experienced strange things. Basically they more from a solaris on phisical machines environment (locally hosted) running an old version of samba (2.x or even 1.x) to a Red Hat virtualized environement runing 3.6 (remotely hosted). The link between clients and server is really good (2x100Mb/s fiber) and browsing shares and opening office

Hi All, I am looking for advice on how to cure a constantly-crashing NFS server which crashes every few hours, or at least, every few days. The kernel log file (below) points toward NFS as a likely cause. The system disk is a 3ware 8000 series RAID1 mirror. The data disk is using a 3Ware 9000 controller to produce two RAID1 devices; these are then striped (RAID0) in software to form a RAID 10

I'm running beta7 on two machines, with maildir on NFS. I have lockd running on all machines. I've found that Dovecot is highly unstable with NFS when accessing a mailbox on more than one machine at the same time. Both dovecot machines have: mmap_disable = yes lock_method = fcntl NFS is version 3, exported from a third linux machine. All machines are running 2.6.9 kernel. Any ideas

We have a 2-node Oracle RAC that keeps getting the following error: kernel: nfs: RPC call returned error 88 The storage being mounted is netapp. We don't see any errors/issues on the storage itself or the switches this client is connecting thru. The NFS network is a 2-interface ( 2 x 1Gb UTP) bond which shows no errors of any kind. We are mounting with the following mount options:

Hi Timo, We've been running Dovecot with Maildir on NFS for quite a while - since back in the 1.0 days I believe. I'm somewhat new here. Anyway... The Wiki article on NFS states that 1.1 and newer will flush attribute caches if necessary with mail_nfs_storage=yes. We're running 1.2.8 with that set, as well as mail_nfs_index=yes, mmap_disable=yes and fsync_disable=no. We have a pool

I would like to verify my understanding keeping in mind I have a one master and one slave computer. When the master gets the low batt/noAC signal it initiates a broadcast packet(s) on port 3493. 1) Is this correct? Then the slave computer must have this port open and it listens on this port for the shut-down command. 2) Is this correct? On the slave if I run the following: steve at MyDesktop:~$

Hi Martin, Thanks very much for the information. I guess the part: * Coherency of the file data you serve with Samba You need to make sure that updates to the data that you are serving are seen coherently across the cluster. Is the tough one. Is there a way to do this that you know of when using NFS? I see version 4.5 RC2 was just released. Do you know when it will be fully released?

Picture: A set of very similar UN*X IMAP servers all NFS-mounting their INBOX area (traditional Unix format) from a common "/var/spool/mail" area; activity for any given user ought to be within one box although this cannot be 100% guaranteed. There is the risk of multiple simultaneous access (e.g. simultaneous LDA/delivers; simultaneous LDA/deliver and user-driven IMAP update; etc.).
