Hi, we're running dovecot 1.1.2 (centos5 32-bit rpm from atrpms) havn't had any real issues with it, but today it looks like an index has become badly corrupted. We're seeing this in the logs every time we log in to a particular account: 2008-09-10T11:56:07+01:00 mail8 dovecot: Panic: IMAP(xxx): Trying to allocate 2273345672 bytes 2008-09-10T11:56:07+01:00 mail8 dovecot: IMAP(xxx):

Hi there, I run a system that has a lot of virtual users. We invoke deliver from exim and pass the directory to deliver into using the HOME environment variable, so deliver doesn't do any database lookups during the delivery process. The exim pipe environment is described at http://exim.org/exim-html-current/doc/html/spec_html/index.html#toc0239, but basically I'd like to know the domain

Hello, can dsync convert from compressed mbox to compressed mdbox format? When I use compressed mbox files, either with gzip or with bzip2, I can read the mails as usual, but I find the following errors in dovecots log file: imap(userxy): Error: nfs_flush_fcntl: fcntl(/home/hrz/userxy/Mail/mymbox.gz, F_RDLCK) failed: Bad file number imap(userxy): Error: nfs_flush_fcntl:

Hi all, Lets say I have a maildir which doesn't contain any dovecot files but has some emails lying around in it. If I add a message to this mailbox using deliver, dovecot creates the uidlist file with a single entry (the message that was just delivered). When I then log in to the mailbox, all the other messages are added into the uidlist file in the normal order (directory list order I

Hi all, We updated to 1.1.7 a week or two back from 1.1.6 (both standard atrpms builds). Since doing so, twice now I've seen the imap services accept connections but they hang before the banner is printed (pop seems to be unaffected). I see this in the logs: Dec 23 14:02:15 mail9 dovecot: pipe() failed: Too many open files Dec 23 14:02:15 mail9 dovecot: Temporary failure in creating login

Hi guys, Anyone know what this error with deliver is (v1.1.1)? 2008-07-03T09:45:19+01:00 mail4 deliver(alexander): Panic: file mail-index-transaction.c: line 642 (mail_index_transaction_lookup): assertion failed: (seq >= t->first_new_seq && seq <= t->last_new_seq) Seen a few of these this morning.

I believe this would be related to some timeouts set on our mysql servers which are pretty

Hi all, We need to set our filestore to read-only for quite a while, and I want to mitigate the effects for our clients. First issue; dovecot. If we just change the nfs mounts to read-only, dovecot complains: 2009-02-19T14:03:19+00:00 mail2 dovecot: pop3-login: Login: user=<test2 at markandruth.co.uk>, method=PLAIN, rip=10.15.10.95, lip=10.15.10.102:11002 2009-02-19T14:03:19+00:00 mail2

Hi, About a week ago I upgraded our reasonably heavily loaded mail servers from a pretty recent courier version to dovecot-1.1rc10. IMAP performance on dovecot is amazing, however POP3 performance is worse than courier :-( I have uploaded some munin graphs taken today to http://linweb.atlas.pipex.net/dovecot/; the dovecot server is handling about 2000 pop logins/sec and 300 imap sessions (but

Dear All, I'm having an intermittent problem, with dovecot slowing to a crawl. Restarting dovecot fixes the problem. Looking at the maillog, I see loads of these errors.... dovecot: pipe() failed: Too many open files dovecot: Temporary failure in creating login processes, slowing down for now dovecot: Created login processes successfully, unstalling looking at the processes, I can see

My existing pop3/imap environment is courier imap + vpopmail + qmail with MySQL backend. I'm looking at migrating this to Dovecot. Currently I have multiple instances of Courier bound to different loopback IPs (the IPs correspond with the virtual IPs on a server load balancer). When a user authenticates they don't have to specify a domain - if they don't, Courier will use a

Hi all, This is just an idea I had over the weekend; I was wondering if instead of storing the indexes/caches on disk, it would be possible to have an option to store them in a remote database (eg mysql). There are several issues that we currently have with scaling dovecot, and I think that if it could store indexes in an external database we could alleviate most of these issues. In no particular

I restored a dovecot mailserver today, and when I started the server again, the logs filled up with "Fixed a duplicate" warnings. This in itself it not a problem, the problem is that it appears the fix is not done correct. Consider this: Warning: Fixed a duplicate: [X]/cur/1305907573.V807I37682f3M146183.mail8.xxx.com:2,S -> 1306601066.M382668P27710.mail8.xxx.com The problem

Hello All, We are struggling to find a solution to a problem we are encountering with a load-balanced email setup. Currently, we have a Coyote loadbalancer, and 3 Postfix/Dovecot nodes that then get their information from a mysql database. The problem is that after a couple weeks, we start seeing NFS locking issues occur, which then takes email completely down, requiring a site visit to

Hi guys, It would be really nice if there were an easy way to see how much space an individual imap account used when a user logged out; something like pop3_logout_format = size=%s. I appreciate that this isn't so easy in imap though - I was thinking of using the quota plugin with no limit or something like that.

Hi, It seems that after I upgraded to 1.1beta1 it takes a few seconds first time I access a folder and i get this error : fcntl(/mail2/home/jon/.Maildir/.INBOX.Pren/dovecot.index.cache, F_RDLCK) failed: Bad file descriptor. No errors after that and it works fine. is this expected. Is it ok to continue using this? Best regards - Jon

Hi everybody, We use a Dovecot setup with GlusterFS. Dovecot 1.1.2 and GlusterFS 1.3.9. I enabled the following options (I don't have posix-locks translators): lock_method = dotlock dotlock_use_excl = no mmap_disable = yes mail_nfs_index = yes mail_nfs_storage = yes I receive the following error message.

Hi there, I'm using dovecot 2.0.16 with a mysql user database. From time to time when we have a big influx of messages (perhaps more than 30 concurrent rcpt to:<> sessions at the same time so no auth-workers free?) or when we have a transient issue connecting to the database server, we see the message: Jan 25 16:38:23 mailbox dovecot: auth-worker: sql(foo at bar.com,1.2.3.4):

Hello, I have recently changed imap from Courier-imap to dovecot because of serial problems with courier-imap, I have being forced to do it very quickly... and without extensives tests. I have 3 mails servers (freebsd based) behind a load balancer and a nfs mailstore on a netapp. On my first tests I have setup the index into some nfs shared mount, but it seems that some imap clients are
