[Dovecot] Can't connect to IMAP

[Dovecot] Experience moving mailboxes from Dovecot 0.99.14 to Dovecot 1.07 = Improvement possible
Hi, This small mail to share my observation about a recent move of mailboxes between two servers and ask about explanation and/or improvement about UIDL in dovecot. SV1 : Dovecot 0.99.14 / Red Hat Fedore Core 4 SV2 : Dovecot 1.07 / CentOS 5.2 Mailboxes in /var/spool/mail on the twoo servers. Test will be done with outlook express with option leave message on server checked. Goal is simply to move users mailboxes from SV1 to SV2 without re-downloading all messages. Try 1: - Stop dovecot on SV2 - Clear all dovecot indexes on SV2 - Rsync of my mailbox - Start dovecot on SV2 - Update pop setting in outlook and send/receive Result : = starting to download 3000 mails... After some debug, I discovered that UIDL where not of the same format = put pop3_uidl_format = %v.%u in dovecot.conf of SV2. Try 2: Same operations as Try1 Result : = starting to download 3000 mails... UIDL's where of the same format but values where not corresponding... Teleting on SV1 and asking UIDL, last value is xx.85878. On SV2, xx.85879 was the FIRST value of the list. Conclusion for the moment, Dovecot has a problem with the detection of existing UID of the moved mailbox. Comparaison of first header found from the two mailboxes show ... differences ! SV1 give the following : (...) X-UID: 70570 Content-Length: 1561 X-IMAPbase: xx 85845 $MDNSent X-Keywords: (...) SV2 give the following (after first POP attempt) : (...) Content-Length: 1561 X-IMAPbase: xx 089204 $MDNSent X-Keywords: X-UID: 85846 (...) Observation : X-UID: 85846 is not at the same place in the header. Try 3: - Stop dovecot on SV2 - Clear all dovecot indexes on SV2 - Rsync of my mailbox - Edit mailbox and move X-UID header after the X-Keywords header - Start dovecot on SV2 - Update pop setting in outlook and send/receive Result : = OK. Is that normal that dovecot is impacted by the position of the headers ? Maybe some improvement possible ? Maybe theyre is another method to make my migration ? Any observation or comment is welcome... -- Benoît Desloges Network Engineer

Re: [Dovecot] expire-plugin: configuration dict-server
Hi Jens,
Ive got the same problem with you. The expire plugin not work. Nothing

And the expire table on mysql never updated.

Hello Eric,
thank you very much for your prompt and helpful reply!
The connect seem to work fine now.
Please allow me two additional questions:
Is it correct that this database-table is only a caching-table which
is empty at first and will be filled later? It is not necessary to
adapt the SQL-statement to my user-configuration, is it?!
Is it necessary to reference the foldernames with INBOX.Trash or
only Trash? For Sieve I have to use INBOX.Trash.
Actually nothing happens when trying the plugin with dovecot

Looking at the rpm it doesn't look like it has bdb support built in. But
it sounds like you want to use Mysql so that's alright.
Are there any further tipps how to use the expire-plugin with
mysql-connection (i.e. database-scheme, SQL-Select)?
You will need to setup your configuration like this:
dovecot.conf:
dict {
...
expiredict = mysql:/opt/dovecot/etc/dovecot-dict-expire.conf
...
}
plugin {
...
expire = Trash 7 Trash/* 7 Spam 3 Junk 3
expire_dict = proxy::expiredict
...
}
dovecot-dict-expire.conf:
connect = host=host dbname=db user=username password=password
table = expire
select_field = timestamp
where_field = path
username_field = username
Then you'll want to create the table like so:
create table expire( username varchar(255) not null, path varchar(100)
not null, timestamp integer, primary key (username, path))engine=innodb;
That should work for you. Of course enter in your correct config
location and your specific expire settings.

[Dovecot] Dovecot proxying results in too many open files
Hi, Some words about my Dovecot setup: - 10 dovecot servers - each server has some local mailboxes - each server has proxying enabled to seamlessly connect to another host if the mailbox is not local Running Dovecot 1.1.1 on FreeBSD 6.3-RELEASE-p3. First of all, local mailbox access is fine. Proxying works also as expected. Now for the actual problem: Shortly after startup, Dovecot starts throwing errors concerning connection which should be proxied. Here are some examples from the logs: Aug 6 15:49:10 dovecot: imap-login: socket() failed: Too many open files Aug 6 15:49:10 dovecot: imap-login: proxy(XYZ): connect(1.2.3.4, 143) failed: Too many open files Aug 6 15:49:10 dovecot: imap-login: accept() failed: Too many open files Aug 6 15:49:10 dovecot: imap-login: socket() failed: Too many open files Aug 6 15:49:10 dovecot: imap-login: proxy(XYZ): connect(1.2.3.4, 143) failed: Too many open files Aug 6 15:49:10 dovecot: imap-login: socket() failed: Too many open files Aug 6 15:49:10 dovecot: imap-login: proxy(XYZ): connect(1.2.3.4, 143) failed: Too many open files Aug 6 15:49:10 dovecot: imap-login: socket() failed: Too many open files Aug 6 15:49:10 dovecot: imap-login: proxy(XYZ): connect(1.2.3.4, 143) failed: Too many open files Aug 6 15:49:11 dovecot: imap-login: socket() failed: Too many open files [..] Aug 6 16:00:05 dovecot: imap-login: accept() failed: Too many open files Aug 6 16:00:08 dovecot: imap-login: accept() failed: Too many open files Aug 6 16:00:11 dovecot: imap-login: accept() failed: Too many open files Aug 6 16:00:13 dovecot: imap-login: accept() failed: Too many open files As from the context it seems to be a file descriptor issue, as such I have done the following: - added a 'limits -e -n 32768 -U dovecot' to dovecot startup file to ensure it has enough FD's - additionally, I've checked my kernel file limits, however I always set it through loader and sysctl to be as large as 64k # sysctl -a |grep files kern.maxfiles: 65535 kern.maxfilesperproc: 32768 kern.openfiles: 1632 - also checked the limits of the dovecot user like this: # su -c dovecot root -c 'ulimit -a' core file size (blocks, -c) unlimited data seg size (kbytes, -d) 1048576 file size (blocks, -f) unlimited max locked memory (kbytes, -l) unlimited max memory size (kbytes, -m) unlimited open files (-n) 32768 pipe size(512 bytes, -p) 1 stack size (kbytes, -s) 131072 cpu time (seconds, -t) unlimited max user processes (-u) 5547 virtual memory (kbytes, -v) unlimited - done some monitoring of file descriptor usage for the dovecot user, though somewhat inacurate, like this: while [ : ]; do date; fstat -u dovecot |wc -l; sleep 1; done this gave me these results while tailing the logfile: Wed Aug 6 15:44:12 CEST 2008 585 Wed Aug 6 15:44:13 CEST 2008 579 Wed Aug 6 15:44:14 CEST 2008 582 Wed Aug 6 15:44:15 CEST 2008 582 Wed Aug 6 15:44:16 CEST 2008 586 Wed Aug 6 15:44:17 CEST 2008 585 Wed Aug 6 15:44:18 CEST 2008 582 So it didn't seem to be anywhere near the theoretical upper limit I've set at 32k. On the other hand, when restarting Dovecot, it works for a few minutes for at least as long as the FD usage as reported above stays at around 500. I remember from the docs that dovecot-login would require the double amount of file descriptors to run. Assuming my report is somewhat inaccurate and lags behind, I could imagine that upon a proxy requests it would effectively peak our at some 500 x 2 FDs. Thus effectively reaching the 1024 FD barrier. I conclude this from the fact that I currently have some 350 - 450 logins in parallel, most of which can and shell be proxied. From the error message in the logs I got the impression, that only proxied connections are affected. I was not able to reproduce the issue with non-proxied logins to local mailboxes. Some further steps I've done from the configuration side to no avail: - disabled imaps/pop3s/ssl - changed between login_process_per_connection yes/no - played around with login_max_connections et all (raised/lowered) limits - tried with/without plugins enabled - tried with SQL-based and passwd-file based userdb/passdb, single and mixed Dovecot config: # dovecot -n # 1.1.1: /usr/local/etc/dovecot.conf base_dir: /var/run/dovecot/ protocols: imap pop3 listen: *, [::] ssl_disable: yes ssl_cert_file: /usr/local/etc/postfix/tls/server.crt ssl_key_file: /usr/local/etc/postfix/tls/server.key disable_plaintext_auth: no verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_process_per_connection: no login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no login_processes_count: 16

Re: [Dovecot] Dovecot proxying results in too many open files
Hi again, Here's some more information on the case. In the meanwhile I tried the same setup with Dovecot 1.1.2, still the same result As I saw in fstat on FreeBSD memory mapped files are ommited, so I did some further yet inaccurate monitoring with mmaped files included. while [ : ]; do date; fstat -m -u dovecot |wc -l; sleep 1; done Wed Aug 6 18:37:05 CEST 2008 918 Wed Aug 6 18:37:06 CEST 2008 923 Wed Aug 6 18:37:07 CEST 2008 917 Wed Aug 6 18:37:08 CEST 2008 911 Wed Aug 6 18:37:09 CEST 2008 912 Wed Aug 6 18:37:10 CEST 2008 914 Wed Aug 6 18:37:11 CEST 2008 913 Wed Aug 6 18:37:13 CEST 2008 912 Wed Aug 6 18:37:14 CEST 2008 911 Wed Aug 6 18:37:15 CEST 2008 909 Wed Aug 6 18:37:16 CEST 2008 912 Wed Aug 6 18:37:17 CEST 2008 910 So actually I am very close to the 1024 FD barrier, so the question remains, if Dovecot inherits FD_SETSIZE from libc and if this might be the cause of the whole trouble. During testing I did also a build of both 1.1.1 and 1.1.2 without SSL and mysql libraries, so basically just plain Dovecout without anything, though that made no difference at all.

Looking at the code it looks like the expire plugin ignores the namespace prefix but expire-tool requires it, so it probably won't work.. No, I'm not using namespaces, or at least not intentionally.

Re: [Dovecot] Server update strategies (was: Experience moving mailboxes from Dovecot 0.99.14 to Dovecot 1.0 7 = Improvement possible)
Hi, it's always interesting to observe and discuss the different update strategies (although not entirely on-topic)... On Wed, 06 Aug 2008 11:25:59 -0500, Eric Rostetter [EMAIL PROTECTED] wrote: Quoting Charles Marcus [EMAIL PROTECTED]: On 8/6/2008, Eric Rostetter ([EMAIL PROTECTED]) wrote: Anyone know about Dovecot 1.1.x rpms for Centos/RHEL 3.x? I'd be more interested in upgrading the server to a reasonably recent version of the distro... Unfortunately, it isn't a redundant setup, so an upgrade is downtime. I've thought about doing an on-line (e.g., yum) upgrade from 3 to 4, but I'm not sure 4 would qualify as reasonably recent and it would still require a reboot, but this is an option and would get me the new dovecot rpms at least... Since there is no good way to do an on-line upgrade from CentOS/RHEL 3 to CentOS/RHEL 5, that isn't really an option at this time (too much downtime). How can such an important system be a non-redundant setup? Hardware breakage (or a cracker, see below) would cause minutes or probably even hours of downtime... I've also had machines that were hardware frozen at older OS versions... Though that is not the case in this instance (was for my print server I had to recently deal with). This is one huge reason why I like gentoo so much. It has nothing to do with gentoo, IMHO. It has in that way, that there are no releases, no big jumps with lots of breakage and config file syntax changes... But I definitely wouldn't say Gentoo is a good distribution for systems that need to be highly available. (I'm using Gentoo myself on desktops and servers, but none of them do run really critical stuff). As long as I update it regularly, I never have to worry about a massive update that breaks everything. Same can be said for most distros, but I can't afford the downtime of the constant upgrades which mean constant reboots... That is why people pick a enterprise solution like RHEL/CentOS, so they can have better uptime (with support) than a non-enterprise systems... Enterprise system - surely sounds professional and all ;) But not rebooting (during scheduled maintenance on a time of week/day where the least clients will be affected) for a new kernel that fixes a critical security issue definitely does not. IMHO. I regularly have machines with 2 or 3 years of uptime before I need to reboot them for an upgrade (they are behind firewalls, in case you wonder how I get along on such old kernels). Maybe you should upgrade your security knowledge along with your kernels ;) Many (if not most) attacks come from the inside (e.g. via trojans/viruses/rootkits on client (laptop) computers). Thus, the concept of something being secure because behind firewalls is at least partly obsolete. Obviously, RHEL/CentOS 3.x will end of life, and I'll need to upgrade eventually because of that, but the more I can put it off, then better... But sometimes you just need to bite the bullet, and that day may be close at hand for this server... Build it with redundancy this time. At least software-wise (for example using virtualisation), so that you have a test system on which you can simulate a pending update before you roll it out on the production system.

[Dovecot] Dovecot auto vacation with sieve doesn't work
Guys, I'm running out of hair to pull out ;).
Can anyone out there say that this does work?? To me this is looking
like a bug and I'm not sure whether it's the sieve plugin or the dovecot
deliver program. I have also had no luck the the reject sending any
reply back to the sender.
My setup:
OS: Solaris 10 sparc platform
postfix: 2.5.2
dovecot: 1.1.2
sieve plugin: 1.1.5
I'm going back forth between procmail and sieve and having no luck.
procmail will send the reply to the sender but doesn't deliver the
message to the recipient. Sieve will deliver the message to the
recipient but doesn't send the reply to the sender. Now if I can just
combine the two, I'll be in business.

You can't use ${1} since variables extension isn't supported by
cmusieve.

You could see if auth_debug=yes shows more. Although debugging PAM
problems is annoying because PAM's logging is so bad.
I find the message in the audit.log interesting because I configured
the connection with SSL not TLS, but if I use TLS the result is the
same.
I think you're confusing SSL and TLS with imaps port and STARTTLS
command (and so do many client UIs..). You're going to be using TLS
connections in any case.

[Dovecot] Maildir Index Question
We have several hundred mailboxes that have thousands of files in them (spam boxes) We currently run a find command and remove the files that are over 7 days old but still have boxes with upto 60k messages in them. I know that dovecot will update the index files for each mailbox when the boxes is accessed by an IMAP client(Webmail using Squirrel)but that can take quite a while to index. What I would like to do is via a cron job after the old file remove is to force dovecot to reindex these boxes. That way when the users login to the webmail interface it is quicker. Does anyone know if a script is available to do this? Thanks Ron Culler

Okay,
Trying to do some debugging of the sieve code. So I have found that
it is failing on sending the reply in the following code area:
bc_eval.c
Line: 324
/* ok, we're willing to respond to the sender.
but is this message to me? that is, is my address
in the [Resent]-To, [Resent]-Cc or [Resent]-Bcc fields? */
But I haven't pin-pointed yet why it's not seeing the message as being
for me??

Timo,
I removed the ${1} variable but still no luck. I read the reasons
why deliver would not send a reply but I don't think any should be true.
Below is the header of one of the messages, let me know if you see
something that is causing sieve not to send the reply.

You can't use ${1} since variables extension isn't supported by cmusieve.
In my testing I know the sieve plugin is reading my .dovecot.sieve
script and creating the .dovecot.sievec, but that is as for as it goes.
The .dovecot.lda-dupes file is not being created (or any
.dovecot.sieve.err file) and no reply is even being attempted from the
logs:
Then it means that Dovecot decided it shouldn't reply to the mail. There
are several reasons for that listed in
http://wiki.dovecot.org/LDA/Sieve (would be nice if it logged the exact
reason though - hopefully the Sieve rewrite will do that :)

[Dovecot] Purpose of files under .imap
I've got a user with an unusable account. Tbird just sits in a loop endlessly logging in over and over when a particular folder is selected. What files under .imap associated with that folder can be safely deleted? What's stored in all of them? I see all of these: .customflags dovecot.index dovecot.index.cache dovecot.index.log .imap.index .imap.index.data .imap.index.log .imap.index.tree

Instead of deleting move the files so that if it's a new bug that I haven't fixed I could take a look at the indexes to see if I can get it fixed. I see all of these: .customflags v0.99-only, delete. dovecot.index dovecot.index.cache dovecot.index.log All of these are safe to delete. .imap.index .imap.index.data .imap.index.log .imap.index.tree These are v0.99-only, delete. So I guess you're using mbox? There it's safe to delete everything. If you're using maildir you should keep dovecot-uidlist and dovecot- keywords.

[Dovecot] Next message unexpectedly lost
Using 1.1.2. I'm getting the above message over and over in the error log.
Dovecot drops the connection and the client (Tbird) just keeps retrying in
an endless loop.
Using Wireshark to sniff the exchange, it looks like the command that fails
looks like this:
5 UID fetch 1:9749,9751:9763,9765:9930,9932,9934:9942 (UID RFC822.SIZE
FLAGS BODY.PEEK[HEADER.FIELDS (From To Cc Subject Date Message-ID Priority
X-Priority References Newsgroups In-Reply-To Content-Type)])
Dovecot seems to be shutting down after receiving this.
Mulberry doesn't seem to have the problem, presumably because it's sending
a different command sequence that doesn't stroke this.
Here's the failing code, in i_stream_raw_mbox_read :
if (stream-istream.v_offset -
rstream-hdr_offset + new_pos rstream-mail_size) {
/* istream_raw_mbox_set_next_offset() used invalid
cached next_offset? */
i_error(Next message unexpectedly lost from %PRIuUOFF_T,
rstream-hdr_offset + rstream-mail_size);
rstream-eof = TRUE;
rstream-corrupted = TRUE;
return -1;
}
I've tried deleting the associated .imap/folder contents but it must
regenerate the same bad data as it happens again.
