[Dovecot] Setting retention policies
by Don Russell 25 Jun '07

25 Jun '07

I access e-mail from different PCs, typically using Thunderbird e-mail client. Thunderbird has a a "retention policy" it can set on a folder by folder basis. Policies such as how long to keep messages for, or how many messages to keep. Is there a way to set those policies on the server itself? Thank you

[Dovecot] Quota from passdb sql
by Bruno Puga 25 Jun '07

25 Jun '07

Hello folks! Is it possible to retrieve quota information from a passdb sql lookup and using static userdb? I've tried here without success, and I can't find in the wiki or forum. Some ways I configured dovecot-sql.conf: 1) password_query = SELECT email AS user, CONCAT('maildir:storage=',quota) AS quota, password FROM users WHERE email = '%u' 2) password_query = SELECT email AS user, CONCAT('maildir:storage=',quota) AS userdb_quota, password FROM users WHERE email = '%u' With userdb sql things worked perfect, but as I can use static userdb I just need quota information per user from passwd sql. Thanks, Bruno.

[Dovecot] quota calculating
by Scott Zahn 25 Jun '07

25 Jun '07

Hey everyone, Currently where I work we use qmail. Every time a message is delivered, qmail seems to walk through the user's entire maildir in order to calculate quota usage. Delivering messages simultaneously to just a few users who are allowed large maildirs (1-2GB) will bring our servers to their knees. Which brings me to dovecot. I use dovecot whereever I can, but haven't yet needed to set up quotas. I would like to migrate my servers at work to use dovecot, but have a few questions regarding quotas. Could someone explain how dovecot calculates quota usage on mail delivery? Also, is there anyone here on the list that uses quoatas on large maildirs (>=2GB)? How well has it worked for you? thanks, Scott

[Dovecot] LIST % not returning correct data?
by J.Wendland＠scan-plus.de 25 Jun '07

25 Jun '07

Hi list, I have namespace private { prefix = INBOX. separator = . inbox = yes } in an installation migrated from courier. I am testing with Outlook Mobile 5 (OM) which uses 'LIST "" %' to get the folder list. Now courier used to return * LIST (\HasChildren) "." "INBOX" whereas dovecot returns * LIST (\HasNoChildren) "." "INBOX" which is why OM failes to display any folder. Is this dovecot's failure or am I missing something here?

[Dovecot] dovecot.conf authentication after Debian upgrade
by Didier Misson 25 Jun '07

25 Jun '07

Hello, I'm new on this mailing list. I run a Dovecot imaps server since several month on a Debian server. I just upgrade a Debian server from Debian Sarge --> Etch and I discover that a lot of parameters have changed (must be changed) in the dovecot.conf. I finally find an exemple an try to adapt it to our server. We never defined special authentification or password scheme. It was simple the "passwd". Dovecot is running, but impossible for users to connect :-( Actually, this is my dovecot.conf : ====================================== base_dir = /var/run/dovecot/ protocols = imap imaps protocol imap { listen = 127.0.0.1:143 ssl_listen = *:993 } # protocol pop3 { # # listen = *:110 # # ssl_listen = *:995 # # } ssl_disable = no ssl_cert_file = /etc/ssl/certs/dovecot.pem ssl_key_file = /etc/ssl/private/dovecot.pem disable_plaintext_auth = no log_timestamp = "%Y-%m-%d %H:%M:%S " login_dir = /var/run/dovecot/login #login_dir = /var/log/dovecot login_chroot = yes login_user = dovecot login_process_per_connection = yes login_greeting = Dovecot ready. first_valid_uid = 1000 last_valid_uid = 0 first_valid_gid = 1 last_valid_gid = 0 mail_extra_groups = mail # #default_mail_env = mbox:/var/mail/%u default_mail_env = maildir:~/Maildir protocol imap { imap_client_workarounds = outlook-idle delay-newmail netscape-eoh tb-extra-mailbox-sep } # # protocol pop3 { # # } auth default { mechanisms = plain ##### Didier Misson : must be check !!! #passdb passwd-file { #args = /etc/dovecot/pass #} #passdb pam { passdb passwd { } #userdb passwd-file { #args = /etc/dovecot/users #} userdb passwd { } user = root } plugin { } ===================================================================== in /var/log/syslog Jun 25 11:14:02 ks36586 dovecot: Dovecot v1.0.rc15 starting up Jun 25 11:14:53 ks36586 dovecot: imap-login: Aborted login: user=<sebastien-descy>, method=PLAIN, rip=62.235.215.24, lip=87.98.219.84, TLS Jun 25 11:14:59 ks36586 dovecot: imap-login: Aborted login: user=<dominique>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Jun 25 11:15:01 ks36586 /USR/SBIN/CRON[16295]: (root) CMD (/usr/local/rtm/bin/rtm 41 >/dev/null 2>/dev/null) I hope somebody already solved this king of problem.

[Dovecot] Dovecot won't stay running
by Jon Slater 22 Jun '07

22 Jun '07

This weekend I upgraded my OS from FC4 to FC6. At the same time I updated Dovecot from 0.99 to 1.0.0. Now, dovecot periodically shuts off. It will run fine for several hours then just dies. Right now my solution is to run a cron every 5 minutes to see if it’s still running, and if not, re-start it. I’m also having trouble finding any sort of meaningful logs to tell me what’s going on. Where should I start? Thanks in advance! Jon No virus found in this outgoing message. Checked by AVG Free Edition. Version: 7.5.472 / Virus Database: 269.9.2/858 - Release Date: 6/21/2007 1:46 PM

Timo, I have sent this message below before but I didn't saw that it was delivered to you personal email instead to the list, I just see this now, sorry. Because I'm in a hurry I gave up using Dovecot + AD and start using Mysql as my userdb and passdb and things worked perfect until the moment. I have some doubts but I will open a new thread for this. Anyway, if you get some news about this issue I would appreciate to know, if not, that's OK. Many thanks for your help. Bruno.

[Dovecot] test program #2: mmaping

21 Jun '07

Attached another test program. I don't expect it to print any errors with any OS, but I'd like to confirm it for non-Linux SMP kernels. (Except for OpenBSD, it doesn't work correctly in it anyway because it doesn't support mixing write()s and mmap())

[Dovecot] Status update
by Timo Sirainen 21 Jun '07

21 Jun '07

I'm leaving soon and I'll be away until sunday. Sorry about not replying to all mails yet, most of them are somewhat tricky and require some time to reply (other than "I don't know"). The new index code for v1.1 seems to be finally working pretty nicely. After 9 hours of running imaptest I haven't gotten a single error yet. I'll leave it running until I'm back. The new code makes the internal index file design a lot easier to understand. For v1.0 I just wanted to get it working and I didn't dare try to clean up the code, so it was kind of magic sometimes why it worked. :) All that magic is finally gone and I understand completely how everything is supposed to work (and hopefully also how it does work). Most important problem with the new code is that \Recent flags are completely broken. I think they're not completely correctly working in v1.0 either, or at least I'm not sure why they're working even as well as they are now.. Maildir syncing in v1.1 is also a bit bad. For example EXPUNGE command could have to be given twice to get it to work. Again it worked badly with v1.0 also but since the index code worked differently it wasn't visible. Cydir is a pretty nice format for stress testing index code. It's really lightweight so it's practically testing only the index code. Because of it I've found a couple of race conditions in the code that existed also in v1.0 tree (v1.0.2 will fix them). My earlier stress testing with maildir never saw those problems, probably because with maildir there was a lot of other code running as well so the race condition was really unlikely to hit.

[Dovecot] pop3 creates bad index file

The only real difference I see with idxview between the dovecot.index created by pop3 and one created by imap is that with pop3 sync stamp is 0, and with imap it contains a timestamp. Onno

"size" means physical message size, "vsize" means the virtual size with CR+LF linefeeds. Does someone want something more?

[Dovecot] Question about pre-indexing maildirs
by David Favor 21 Jun '07

21 Jun '07

I have a situation with many users and an existing mail delivery agent. Seems like I once saw an imaptest program which I imagine might be used to pre-index maildirs. For example... - remember which users and user maildirs have changed since last pre-index - when system quiet pre-index any maildirs which have had mail delivered and no access by a mail client (using some inotify magic) If this sounds do-able, let me know where I can find an imaptest version which works with latest dovecot trunk code and the syntax for using it. Seems like I saw this once on the dovecot site. Thanks. - David -- Like feeling your best ever, all day, every day? Here's how... Your simple secrets are here - http://RadicalHealth.com

Please test and reply (but don't bother if someone already replied with the same OS+result). I expect it to print: - SMP kernels: "page size cut" once in a while - UP (uniprocessor) kernels: Nothing - The most important thing is that it never prints "broken data" It might take a while for it to print anything. With my computer it takes anything from a few seconds to a minute or so. See the file itself for compiling/running instructions. So far I've tested only with Linux 2.6.21 x86-64/SMP and a slow Solaris/Sparc/UP. If you're interested in knowing what this is about: Dovecot writes to dovecot.index.log files by first writing the transaction with its size being 0. After that it writes the 4 size bytes again (using a bit special format with all bytes ORed with 0x80). I expected that when another process is read()ing the file and it notices the size being valid (all bytes having 0x80) that the whole transaction could always be read. But looks like if the size happens to be just before a memory page boundary, it's possible that the updated size is read, but the rest of the transaction isn't.

[Dovecot] (OT) Advice on best way to collect mail from multiple domains and deliver to users via Dovecot IMAP.
by Dave Hatton 20 Jun '07

20 Jun '07

Hi Sorry if this is an inappropriate question to ask here. If it is maybe there is a better place to ask this question? I would like to collect email sent to multiple users (with previously unknown usernames) sent to multiple domains and then deliver this email to a specific set of users on my server based upon some predefined rules, with a catchall for mails that aren't caught by these rules. So as an example, I might have domains:- example.com, example.co.uk, someotherdomain.com and I'd like to say to a sender "just send a mail to anything(a)example.com". I'd like to be able to make up recipients on the fly when subscribing to a service so that I can filter mails to this address out at a later time. The method I devised when I set this up using dovecot .99 is as follows. I currently have the hosting service for the domains forwarding all email to a singular mailbox at my ISP and I user fetchmail to pop3 the mail down from this one mailbox. The mail is then passed to postfix where I use the luser_relay option to map all unknown recipients to a local address so that it doesn't get bounced. Postfix then delivers the mail via the mailbox_command to maildrop where a series of rules inspect the envelope headers and write the mail using the "to" option to an appropriate maildir for the target user. Is this a good approach? Would I be better off using dovecot LDA and sieve? Any advice or ideas would be gratefully received. Daveh

[Dovecot] save failed to INBOX
by Erland Nylend 19 Jun '07

Hello, I'm seeing som error messages in the mail log, like this: Jun 12 12:50:44 <mail.info> smtp2 deliver(user1(a)domain.tld): msgid=<10784847.1181644475592.foo.bar@foo99>: save failed to INBOX Jun 12 12:50:44 <mail.info> smtp2 deliver(user1(a)domain.tld): msgid=<30757588.1181644556388.foo.bar@foo99>: saved mail to INBOX It seems that when two or more messages are being delivered at the same time, only one delivery succeeds. Both the maildirs and the indexes are stored on a SAN .. I'll try to read the source, to find out whether this is a locking problem. I would think that if a deliver -process finds that a maildir is locked, then it should wait, and retry? -- Erland Nylend
