Panic: IMAP: Trying to allocate 2273345672 bytes
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:

Poor pop3 over nfs performance
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

help: "dovecot: pipe() failed: Too many open files"
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....

usernames with/without domain - my solution
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

nfs_flush_fcntl failed: No locks available
Hi there,
I've been seeing this error in our logs quite frequently on our nfs
storage (v3):
2008-11-10T13:24:26+00:00 mail8 dovecot: IMAP(XXX at YYY.com):
nfs_flush_fcntl: fcntl(/var/spool/mail/XXX/Maildir/dovecot.index.cache,
F_RDLCK) failed: No locks available
Which is because we don't run lockd on our servers. Why is dovecot
trying to use fcntl() ? I explicitly set it to use dotlocks

Feature Request - Director Balance
Hi,
often I run into the situation where a dovecot server goes down for
maintenance, and all users get concentrated in the remaining dovecot server
(considering I have 2 dovecot servers only).
When that dovecot server comes back online, director server will send new
users to it, but the dovecot server that was up all the time will still
have tons of clients mapped to it.
I suggest the director

Unbreakable NFS locking issues...
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

%d in deliver
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

Is Dovecot Director stable for production??
Today I will try Dovecot Director for a setup using a Cluster Backend with
GFS2 on rhel5, my question is if is Director stable for use in production
for large sites, I know is mainly designed for NFS but I believe it will do
the job also for a cluster filesystem like GFS2 and should solve the mail
persistence problem with a node and locking issues.
I plan to add a layer behind a load balancer to

Dovecot deliver uidlist issues
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

1.1.6 -> 1.1.7 regression: dovecot: pipe() failed: Too many open files
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:

(new) director issues in 2.1.10
Timo - I upgraded to 2.1.10 on our director servers two nights ago and
apart from errors associated with the directors processes restarting
everything looked great for ~24 hours until I failed our the real
servers last night to update the nfs mount options for the spools.
I followed the suggested procedure for each backend server, just run on
one of the directors, which seemed to work as

Passdb disconnected unexpectedly when trying to do Director with LMTP
Hi there,
I'm running Dovecot 2.0.16 just set up the director with cut&paste from

Effects of going read-only on dovecot & pop/imap clients
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:

4sec latency when using director
Hi,
I've been running dovecot for many years, but now i've hit a strange
problem.
when retrieving imap there is sometimes in 1 of 4 imap requests a 4sec
latency.
* notes:
- connected directly to the backends this latency disappears
- removing a director from the loadbalancer(lvs) so i'm the only connected
to the director
this latency disappears too
I would appreciate some feedback

RFC: Storing indexes in a (remote) database to increase dovecot scalability
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

auth-worker temporary failures causing lmtp 500 rejection
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
