[Dovecot] [PATCH] move highest_fd calculations to ioloop-select.c
by Andrey Panin 25 Aug '04

25 Aug '04

Hello, ioloop->highest_fd is used by ioloop-select.c only, so its handling can be moved out of generic ioloop code. Attached patch (agains -test35) does exactly this. Please consider applying.

I guess ssl_ca_file is newer than 0.99. I have the same settings (debian -sarge) and i am using ssl_cert_file and ssl_key_file to get the certificate working. I checked ssl_ca_file and i got the same error, nevertheless it's in the recent dovecot.conf file from 1.x.testing, therefore it should be newer than 0.99.

[Dovecot] Unknown setting: ssl_ca_file
by Jacob Elder 24 Aug '04

24 Aug '04

I am using 0.99.10.7-1 on Debian, and I'm having some trouble with SSL. I purchased a certificate from Thawte and I can't figure out how to tell dovecot about the CA cert. Adding ssl_ca_file to my configuration produces "Unknown setting: ssl_ca_file" on dovecot startup. Postfix has a smtpd_tls_CAfile argument and that part is working fine. Is this a Debian-specific problem or is ssl_ca_file newer than 0.99.10.7? -- Jacob Elder

[Dovecot] Newbie: dovecot not running.
by Simon Waters 23 Aug '04

23 Aug '04

Okay, sure it must be trivial.... I have old Redhat box, want a quick and dirty IMAP server, thought good time to try out dovecot (I'd rather it had Debian on too ;). Downloaded and compiled from source - no options to configure. Auth data is in /etc/passwd and /etc/shadow (as well as NIS). vi /usr/local/etc/dovecot.conf as expected. Disable ssl in conf. Basically email is in mbox format in /var/spool/mail/%u Should go somewhere ~%u/mail is fine, as would be ~%u/Mail (I don't care at the moment). created a user "dovecot..." to run as and edited conf file. If I run /usr/local/sbin/dovecot it terminates without errors, the fork is completing I think, and the main program returns as expect. Running imap-auth from xinetd gets me a greeting banner, but then the connection is closed. Trying to run "imap" directly just dies in a blizarrd of "dot locking" errors and the like, where it seems to ignore the locking directives (should I set an env or some such?), but I think that it is basically running (it creates indexes in ~/mail/...mumble) but complains about the dotlocking, and then spews an internal error (which it claims is logged to server log?). I'm off to try auth_verbose, but any tips or hints appreciated. I'm assuming /usr/local/sbin/dovecot is what was called "master" given it is in the master src directory. Simon

[Dovecot] 1.0-test33
by Timo Sirainen 23 Aug '04

23 Aug '04

http://dovecot.org/test/ I think I found and fixed the last bug that was giving me problems. Now that Dovecot has been successfully working for a few hours, time for a new test release :) This release has major changes, so there might still be some bugs left. Be careful. If you're upgrading from previous 1.0-test release, you must delete all existing dovecot.index.log files or you will get errors. So, the changes are: - All network sockets are nonblocking now and all the waiting is done in a single event loop. This required tons of changes all over the code. - Transaction log file doesn't use locks for reading anymore - Some mbox fixes - search text was broken

[Dovecot] MIME structure intermittently lost
by Kenneth Porter 23 Aug '04

23 Aug '04

I'm using Dovecot-0.99.10.5-0.FC2 on Fedora Core 2 on the server, and Mulberry 3.1.6 over Win2kSP4 on the client. Intermittently messages with multiple parts show up as a single text part. I'm not sure if it's Mulberry or Dovecot. I just turned on IMAP logging and restarted Mulberry and a message with two text/plain parts that wasn't showing the 2nd part is now displaying it correctly. I hate heisenbugs!

Client should never see any "real" error messages to make sure no extra information about the system gets leaked. So any time something unexpected happens, Dovecot gives the "internal error" message to user while writing the real error to log file. The timestamp is there to help sysadmin find the real error message from log files when user gives a copy&pasted internal error message. Instead of timestamp I guess there could be also some unique identifier which could be grepped from logs but I think timestamp is better. And about the original problem of giving "internal error" when Dovecot process didn't have access to some maildir.. Maybe it could have replied "Permission denied" to client in that case. It already does in several cases, but I guess the problem here was that it was trying to create the missing dirs but couldn't. I'll look over all these permission issues properly when creating real shared folder support.

Did Dovecot actually crash? Did it log a more sensible error message to syslog? I think Dovecot quite often reports an "internal error" to the client but then writes a more sensible error message to syslog. Which is probably no bad thing as you may well not want clients to see detailed error messages - there's nothing they can do about it anyway. Andrew

[Dovecot] Multiple dovecot processes stepping on each other

I have two instances of dovecot running, one for v6 and one for v4 connections. The only differences in the config files are: --- /etc/dovecot-ip6.conf Wed Aug 18 11:15:43 2004 +++ /etc/dovecot-ip4.conf Wed Aug 18 11:09:17 2004 @@ -10,7 +10,7 @@ # *** NOTE *** Some values HAVE been changed for OpenBSD use. # Base directory where to store runtime data. -base_dir = /var/dovecot-v6/ +base_dir = /var/dovecot-v4/ # Protocols we want to be serving: # imap imaps pop3 pop3s @@ -23,7 +23,7 @@ # "host:port", although with multiple protocols you probably want to move # this setting inside protocol imap/pop3 { ... } section, so you can # specify different ports for IMAP/POP3. -listen = [::] +listen = * # IP or host address where to listen in for SSL connections. Defaults # to above if not specified. For the most part it is working, but every so often, the auth freaks out for one (random) account.

If you try again immediatly, it works. If I do a `ps -p 21082` I can see the process (dovecot-auth). This does not happen when I have only one dovecot process running.

[Dovecot] Dovecot stop accepting command When reading disk quota (soft)
by Chan Min Wai 23 Aug '04

Hello all, I've face some problem here and I think it should be the way. 1) I'm running Dovecot version 0.99.10.4 (fc1 release) on RH9 2) One of the users have reach the soft disk quota limits 3) Dovecot stop the users from deleting email. What I think was, dovecot should let the user continue to use the services until it reach the hard limits, but pop up message each and every time ;). Anyone have that problem before?

[Dovecot] What about saving your INBOX at ~/mbox ?
by Nico Kadel-Garcia 23 Aug '04

23 Aug '04

Hi, folks. I'm testing out RedHat's "Fedora Core 2" release, which has switched from the old WashU imapd to dovecot-0.99.10. Overall, this looks like a really, really good move on their part: it looks like a very sweet little tool without some of the ingrained idiocy of Mark Crispin insisting that every home directory consist of nothing but mbox files and allowing you to use a configurable subdirectory by default, ~/mail. Cool. There is one feature of the old WashU imapd that I miss, though. That daemonn could be configured to automatically transfer the user's email to the "~/mbox" upon activation of the daemon, effectively reducing the size of the /var/spool/mail/{username}" mail spool and helping keep the user's disk usage in their home directories, not in /var/spool/mail. This can be a good thing for various reasons. But I don't see any way to enable that behavior for dovecot. Is there something I'm missing, or do folks feel it would be reasonable to add? -- Nico Kadel-Garcia Systems Engineer Mitsubish Electric Research Lab <nkadel(a)merl.com>

[Dovecot] Is 1.0-test stabilising?

Has Timo backed off work, and been busy with something else, or has 1.0 really stabilised that much?

I'm hoping it's ready for release... but if it's just that Timo's busy, well, I can understand that.

I thought that Dovecot was supposed to handle that kind of thing? Reading from the website: "Any kind of crash is considered as bug and will be fixed - even if it happens only by deliberately poking the index files." I've done it in the past by just creating the bare folders - they appear in the IMAP folder list then when they're used Dovecot seems to create the sub folders anyway. The issue I'm asking about here is, should the error message say "Internal Error [date time]" rather than something useful?

[Dovecot] Unusual behaviour
by Mark Lidstone 20 Aug '04

20 Aug '04

Hi, I've just noticed something strange in dovecot 0.99.10.5. I created some IMAP folders from the command line (mkdir .INBOX.Folder1) as a different user to the owner of the mailbox. Obviously when I tried to view them via IMAP I got an error message, but the message to the client was "internal error[date time]" where date and time appeared to be the current date and time. Is this correct behaviour? Dovecot was running on FC2, and the client was Mozilla Thunderbird under Windows.

[Dovecot] Question: email system architecture
by Gland Vador 18 Aug '04

18 Aug '04

Hi, I have a question about how to implement a mail system, but I don't know where to ask. Until now, I have a mail system who receive mail by postfix and transport it through procmail to the /var/spool/mail/username mailbox. From here it is retrieved through dovecot (POP3). Now I have two more users, I want to implement a IMAP server, and also provide a webmail (squirrelmail) interface. And in order to filter spam, I want to install spamassassin. Until now it was thunderbird who made the filterring, but with a webmail interface it's no more possible. So suppose that I have configured procmail to deliver "good" mail in an Inbox folder and "spam" in a SPAM folder. This for each user mailbox. I also have configured dovecot as IMAP server and any IMAP client can see the two folder with spam and ham. And here comes my implementation problem. If a user see a "good" mail in his spam folder (or vice-versa) he will take this mail and move to his inbox folder. But, I want to be able to say to spamassassin to learn that this message is ham, with the command sa-learn, and also remove the x-spam* headers. And I don't see a good way to do that. In my opinion, it should be the MUA task, but spamassassin is server based. It's any way that dovecot when it moves the mail between tho folders can call an external script who will make this job in fonction of source/destination folder? Maybe it's a silly question (I don't know IMAP and his possibilities). In this case, can anyone explain (or point to) me a way to do that ? Sorry for this long message. Edd.

[Dovecot] We couldn't drop root group privileges.
by Greg M 16 Aug '04

16 Aug '04

Hello all, This is my first post to this list. I have tried finding this answer online but while it seems that there are some people out there asking, I cant seem to get an answer to it. I have installed Dovecot some many month ago, and just recently I have been getting an error while trying to log into one of my accounts that I used all the time. The error that comes up is pop3: We couldn't drop root group privileges I have seen where someone else has asked this same question, but there was no response to the list. Anyone have any ideas? I use squirrel mail to check the account as well as KMail (IMAP), and have even tried logging in through telnet to port 110 to see if it was a client issue, but it appears to be dovecot. I am using BSD 4.9 and Exim if that helps any. Thanks a bunch, for now I have to ssh into the machine to check my mail via PINE or mail. -Greg M.

[Dovecot] no local users - mbox all under /var/spool/mail/
by Daniel 15 Aug '04

15 Aug '04

Hi there, im new to dovecot but I made my way trough configuring it. I almost get it running at least for one IMAP user. The problem is I got no local user thus no home directories, all Mailboxes are in mbox format under: /var/spool/mail: Looks like this: -SNIP- drwx------ 3 web1p2 poponly 19 2004-08-13 00:05 indexes -rw------- 1 nobody nobody 0 2004-03-26 21:51 nobody -rw------- 1 root root 0 2004-03-26 21:51 root -rw------- 1 web1p2 poponly 14 2004-08-13 00:10 .subscriptions -rw------- 1 web1p2 poponly 8571 2004-08-13 00:10 Trash -rw-rw---- 1 web0p1 root 23068262 2004-08-12 21:27 web0p1 -rw-rw---- 1 web0p2 root 17749 2004-08-12 23:55 web0p2 ... -SNAP I´ve set up the mail-environment this way: default_mail_env = mbox:/var/spool/mail/:INBOX=/var/spool/mail/%u:INDEX=/var/spool/mail/indexes/%u The problem is, that the directory "indexes" has permisions that only the owner can write to (well, I could change permissions, but?) and that the ".subscription" file and "Trash" folder is directly in this directory. So if I add a second user (e.g. web0p1) I got error messages imho due to the use of the "same" folder....? What would be the proposed setup for this system with mostly non-local users without real home directories and all their mbox in a shared directory? Thanks for your time! Daniel

[Dovecot] LDAP-auth not working
by Roger Bystrom 15 Aug '04

15 Aug '04

I have set up dovecot to use ldap authentication, but it only results in dovecot crashing without any error message that would indicate why this is the case. I have spent *many* hours trying to fix this problem, but not found any solution as to why it should crash. maillog: Aug 15 10:05:08 era dovecot: Dovecot starting up Aug 15 10:05:09 era dovecot: Auth process died too early - shutting down Aug 15 10:05:09 era dovecot: child 20833 (auth) killed with signal 11 Aug 15 10:05:09 era imap-login: fd_send(-1) failed: Broken pipe Settings to indicate ldap in dovecot.conf: auth_userdb = ldap /etc/dovecot-ldap.conf auth_passdb = ldap /etc/dovecot-ldap.conf Basically, the settings in dovecot-ldap.conf is: hosts = localhost:389 dn = cn=dovecot,ou=servers,dc=remiss,dc=org dnpass = nada base = dc=remiss,dc=org deref = never scope = subtree user_attrs = uid,homeDirectory,,,uidNumber,gidNumber user_filter = (&(objectClass=posixAccount)(uid=%u)) pass_attrs = uid,userPassword using ldapsearch -x -D "cn=dovecot,ou=servers,dc=remiss,dc=org" -w nada .... is successful. Therefor I am wondering what in the world that causes "Auth process" to die too early. Output of strace -f dovecot -F is available from http://remiss.org/download/log Pid of auth-process here is 23286. Any help is appreciated. Thanks, Roger.

[Dovecot] Dovecot Local Delivery Agent
by news.gmane.org 12 Aug '04

12 Aug '04

Hi I noticed in a post that Timo might start work on a LDA Great! If so, here is something I would really like included. Support for PAM There is quite a lengthy reason behind this. In my organisation, user accounts are created on ldap. It is up to the services to create home directories whenever the user first uses them. For instance, Samba will do this the first time they connect to their windows home share. This achieved in other places using pam, using the pam_mkhomedir module. The MTA we run, Exim, is incapable of creating the home directory automatically, or using PAM for local delivery, thus we have the problem that when an account is created in the LDAP directory, it cannot receive email until the user first logs in through IMAP - Dovecot calls pam, which creates the home directory :-) Also attributing to this is the fact that exim is configured to deliver email into $home using maildir format rather than a mbox mail spool. We needed to do this because of the huge size of some of the inboxes of our users. This caused a severe amount of i/o blocking. So far, I have been unable to find a LDA capable of doing this. Since we migrated to dovecot, performance has improved ten-fold. I will give it a week then show you the graphs to prove it! Keep up the great work!

Although I'm not extremely familiar with default OpenBSD installations, it's been typical for default RedHat installations (up to and including RH 9) to have sendmail installed and configured to use procmail for its LDA. while recent versions of procmail can support maildir format, it defaults to using mbox format. alan

Now when is whould like ad a folder via imap i get an error imap(user(a)domain.com): mkdir(/var/mail/domain.com/user@domain.com/.test) failed: No such file or directory It should be mkdir(/var/mail/domain.com/user/.test) Is there a way to configure this?

[Dovecot] Problem moving folders with Thunderbird
by Loek 10 Aug '04

I can move around folders to sub-folders in an IMAP account on my dovecot server, but when I try to move a sub-folder back to the top-level (by dragging it to the account name), I get an error: "The current command did not succeed. The mailserver responded: Mailbox exists." It doesn't exist on the server though, and I can create a folder with that name on the top-level. But it is a little annoying. I am using TB 0.7.2. I tried different IMAP server settings in Thunderbird under the account options, but without success. Loek

Hi, I would like to know if it's possible to configure dovecot so that it use mbox file format for the INBOX mailbox but Maildir format for all the subfolders. My problem is I would like an IMAP server which allow to easily create folders and subfolders of folders, but at the same time I don't want to break all MUA which rely on /var/mail/johndoe in mbox format. Thanks in advance. Yann

Re: [Dovecot] Dovecot Local Delivery Agent

Timo, a very simple save-only LDA would be enough for many configurations. Other full featured LDAs such as procmail could also use dovecot-LDA as the final delivering program. This would keep gigantic mboxes always indexed, and make access on them snappy always, especially on the important first access. However this should not take many programming resources away from releasing a robust, migration-ready v1.0. I am eager to migrate 25,000 users (~100GB), onto dovecot and then provide them more disk space, which now I dare not allow them. Keep up the excelent work! apap > Date: Mon, 9 Aug 2004 02:03:53 +0300 > From: Timo Sirainen <tss(a)iki.fi> > Subject: Re: [Dovecot] Dovecot Local Delivery Agent > To: Dovecot mailing list <dovecot(a)dovecot.org> > ... > Anyway, I'm still hoping someone else to do the LDA so I don't have to > worry about it.

[Dovecot] Little problem with dovecot using mbox format
by Jd 09 Aug '04

09 Aug '04

Hi everyone, this is my first post on this mailing list. I recently installed postfix+dovecot+fetchmail on OpenBSD for my dad's office. (dovecot is setup as an imap server using mbox). Everything worked flawlessly...until now. I don't know why, but now some emails seem to de-double themselves. For exemple, yesterday morning I printed out all the emails. To my surprise 30 minutes later, I received 60 'new'' emails. But these 60 emails weren't new, they were all copies of emails I had printed out earlier. Some emails were repeated some 10-15 times. Now we never got this kind of problem until recently. Has anyone ever experienced this kind of problem? If so how did you fix the situation? Most responses I got from the openBSD mailing list was to use maildir format. Any insight into this? Thanks, Jean-Daniel BTW we don't get THAT much email, maybe 200 a day for that 1 account that seems to be acting weird now.

My current goal is to make it mature enough and good enough where people might actually want to do that -- as I say, by finishing up some of the things that are still undone. Also there are a couple of things that are hardwired to the environment here (particularly, the way that the IP addresses are extracted for DNSBL tests), that I felt that I should make more general before making it open. The latest sources are available online to anybody who wants them, for use in your own environment, for experimentation and trial, but not for redistribution; but indeed if there was some demand I would probably open it up sooner than later. So far nobody has been beating down the door for it (admittedly I haven't really mentioned it in very many places; I think only here and on the bsdi-users list). But yeah, the plan is to make it so that you can modify it and redistribute it. I don't have any kind of hard and fast position on when, though. I'm sure most anyone could convince me to open it up most any time, if there was good reason to do so. mm

[Dovecot] search functionality
by Cor Bosman 06 Aug '04

06 Aug '04

Hi all, if I give the following command in test32: A004 UID SEARCH CHARSET ISO-8859-1 ALL TEXT {4} Test The response is: * SEARCH A004 OK Search completed. If I say: A004 UID SEARCH CHARSET ISO-8859-1 ALL FROM {4} Test The response is: * SEARCH 217 350 A004 OK Search completed. The RFC says that 'TEXT' is supposed to result in a list of messages where the search string is in either the body or the header. Obviously the string is there in this example, else the FROM search wouldnt have given a result. Tracing the process shows that dovecot never actually checks the email messages for the string. It does for a BODY search but not for a TEXT search. Is this on purpose? Cor

[Dovecot] dovecot-auth: Aug 04 10:48:29 Fatal: Unknown userdb type 'mysql'
by Alex Low (e-wise) 06 Aug '04

Hi, I am trying this way(mailinglist), as I cant find good 'support'/howto/tutorials on the website. I am running Fedora Core II, using postfix with mysql, and I want to use dovecot as imap server. Now I installed Dovecot using dag wieers SRPM, I compiled it with mysql, pgsql; %configure \ --with-ssl="openssl" \ --with-ssldir="%{_datadir}/ssl" \ --with-ldap \ --with-pgsql \ --with-mysql \ --with-cyrus-sasl2 \ --with-rawlog %{__make} %{?_smp_mflags} After compiling it, I installed the rpm. No problem at all. I configure the dovecot.conf like this; #auth = plain digest-md5 #auth_methods = plain digest-md5 auth_userdb = mysql /etc/dovecot-mysql.conf auth_passdb = mysql /etc/dovecot-mysql.conf default_mail_env = maildir:/home/mail/virtual/%d/%n # Use this logfile instead of syslog(). /dev/stderr can be used if you want to # use stderr for logging (ONLY /dev/stderr - otherwise it is closed). log_path = /tmp/dovecot/log1 # For informational messages, use this logfile instead of the default info_log_path = /tmp/dovecot/log2 Then I try run it: [root@octa SPECS]# cat /tmp/dovecot/log1 dovecot-auth: Aug 04 10:48:29 Fatal: Unknown userdb type 'mysql' dovecot: Aug 04 10:48:29 Error: Auth process died too early - shutting down dovecot: Aug 04 10:48:29 Error: child 2118 (auth) returned error 89 imap-login: Aug 04 10:48:29 Fatal: fd_send(-1) failed: Broken pipe dovecot-auth: Aug 04 11:04:39 Fatal: Unknown userdb type 'mysql' dovecot: Aug 04 11:04:39 Error: Auth process died too early - shutting down dovecot: Aug 04 11:04:39 Error: child 11137 (auth) returned error 89 imap-login: Aug 04 11:04:39 Fatal: fd_send(-1) failed: Broken pipe imap-login: Aug 04 11:04:39 Fatal: fd_send(-1) failed: Broken pipe [root@octalys SPECS]# cat /tmp/dovecot/log2 dovecot: Aug 04 10:48:28 Info: Dovecot starting up dovecot: Aug 04 11:04:38 Info: Dovecot starting up [root@octalys SPECS]# Can anyone tell me whats wrong please ?

[Dovecot] Dovecot Courier
by Michael Baird 06 Aug '04

06 Aug '04

Hello, I've been testing dovecot, and it appears to be much faster then courier-imap. I am using the latest .99 version, trying to make the transition from courier to dovecot as smooth as possible. We really only use IMAP via squirrelmail, I think I've got that worked out fine, changing a few settings in squirrelmail as the FAQ instructs and migrating the courier subscriptions to .subscriptions. I've noticed the folders .Trash .Sent are no longer subfolders of the INBOX,, and when I create new folders in a Client, it creates .INBOX.foldername, and a .INBOX. I would really like all folders to be subfolders of .INBOX, I've set dovecot up as the following. default_mail_env = maildir:/var/export/%h/.maildir:INDEX=/var/indexes/%n I've also tried putting the INBOX:/var/export/%h/.maildir in there as well with no luck. I essentially want .INBOX to be .maildir, and any subfolders would be called .Sent or .Trash or whatever, like in courier, is this possible? Regards MIKE

[Dovecot] Adding mail to dovecot directories
by Chris Dean 03 Aug '04

03 Aug '04

I run mailagent (which is similar to procmail) to filter all my incoming messages. I would like mailagent to put these messages directly into my dovecot server. What I'm doing right now is to create files (one per message) in the "~/mail/.folder-name/new" directory, or in the case of INBOX, in the "~/.mail/new" directory. I have ~/.mail as my maildir. The files created have MH style names: "1", "2", etc. and the names are often reused throughout the day. That is, the file named "1" might be created dozens of times per day with new contents. Is this the right way? Regards, Chris Dean

Re: [Dovecot] SSL CA root certificate
by Mail Admin 03 Aug '04

03 Aug '04

Problem solved. In my case I was using the 0.99.10.x release of dovecot, which does not recognize the ssl_ca_file directive. Upgrading to 1.0-test32 was step one. The next step was finding the right format for DST's root certificate. I think the format that finally worked was the format DST distributes for Apache Raven. Thanks!

[Dovecot] SSL CA root certificate
by Mail Admin 02 Aug '04

02 Aug '04

In reading through the mailing list, this question seems to have come up before, but never quite answered. I bought a certificate from Digital Signature Trust which is a well known certificate authority. The reason I bought my certificate, was so that email clients connecting to my imaps server wouldn't be bothered with warnings of unrecognized certificate authority as they would see with a self-signed server certificate. However, I haven't been able to configure dovecot with my Digital Signature Trust signed certificate so that the unrecognized certificate authority warning doesn't appear. I have the root certificate for Digital Signature Trust, but I don't know where to put it so that dovecot will use it. I tried appending the CA root certificate onto my server's certificate file with no success. The answer here is not, load my server's certificate into thunderbird or outlook express, because that is exactly what I'm trying to avoid by purchasing my certificate from a recognized authority. Help. Thanks, Derek

[Dovecot] Too many open files with test32

Hi Timo and others, I'm using test32 since today and I'm getting this error once every 2 hours or so: dovecot: Jul 30 20:21:26 Error: IMAP(jens(a)gutzeit.at): open(/var/mail/data/jens/jens(a)gutzeit.at/maildir/.INBOX.Gentoo.Security/dovecot-uidlist) failed: Too many open files dovecot: Jul 30 20:21:26 Error: IMAP(jens(a)gutzeit.at): file maildir-uidlist.c: line 147 (maildir_uidlist_deinit): assertion failed: (!UIDLIST_IS_LOCKED(uidlist)) The problem is not specific to this mailbox. I hadn't this problem with the stable releases and I've also not set any special limits for the dovecot processes. I'm using a grsec pathed kernel (linux 2.6.7), the kern log says: grsec: attempted resource overstep by requesting 1024 for RLIMIT_NOFILE against limit 1024 by /usr/local/libexec/dovecot/imap[imap:19114] uid/euid:1011/1011 gid/egid:448/448, parent /usr/local/sbin/dovecot[dovecot:7799] uid/euid:0/0 gid/egid:0/0 Does dovecot really need more then 1024 filedescriptors or is it a bug?

[Dovecot] mailsync: NO Unexpected EOF

Hello, I am trying to migrate off a MS Exchange 5.0 server. I am using mailsync (http://www.linux-france.org/prj/imapsync/) to copy the files to a Dovecot server, version 0.99.10.7. For particular messages I get the following error: Couldn't append msg #114081 (Subject:[RE: balh blah]) to folder INBOX: Error trying to append: 826 NO Unexpected EOF I think this is Dovecot, complaining about the message text that imapsync is trying to append/write.

http://dovecot.org/test/ Ok, another one. Fixes somewhat rare crashes with transaction log. mbox won't deadlock anymore. read-only mboxes work finally ..
