[Dovecot] how to migrate from one server to another?
by Bram Mertens 06 Sep '05

06 Sep '05

Hi I have purchased and installed a new PC and would like to transfer my mail (in Maildir format) to it. Are there any precautions I must take before copying the mail over? I will disable mail delivery temporarily so no new mail gets written to disk but I don't know if dovecot has to be stopped before copying/editing mail for backup or migrating purposes. Anything else I must pay attention to? TIA Bram

[Dovecot] dovecot + openwebmail
by Peter McEvoy 05 Sep '05

05 Sep '05

Hi, I'm trying to add some sanity to a badly thought out mail system that, for various reasons, cant be fixed from the bottom up at this moment in time. The system is debian sarge, exim 4.5, doing virtual domains and delivering into mboxes in /var/spool/virtual/$domain/$user , there is webmail access and this allows user to create folders in (dont shoot me!) /etc/openwebmail/users/$domain/$username/mail/ , the files in this directory appear to be mboxes in that each mail begins with a From: line, the naming of these files is completely arbitrary. Im trying to add imap access that would ideally give users access to the mail in /var , and also in the openwebmail dirs, though the latter is not essential, just desirable. All mails are owned by user mail. I've installed dovecot-imapd version 0.99.14-1, but if this doesnt have the namespace additions from version 1.0-test, I can easily install that. Reading the wiki, it seems I can achieve this with namespaces, something like namespace private { separator = / inbox = yes prefix = location = mbox:/etc/openwebmail/users/%d/%u/mail:INBOX=/var/spool/virtual/%d/%u } But, Im not quite sure where this would go in the config file, going by the example config you can just shoehorn them into the middle of the file, but I'm not 100% sure... I had been trying to use things like.. default_mail_env = mbox:/var/folders/%d/%u:INBOX=/var/spool/virtual/%d/%u:INDEX=/var/indexes/%d/%n Having created the necessary folders in /var , but I didnt have much success (the authentication part worked straight away using my passwd file), And having read more and been told about namespaces on the irc channel, it seemed like I should go that way anyway. If anyone could give me a steer in the right direction, or even tell me i'm wasting my time (tho dont bother telling me how much better maildir etc is, i know!) Thanks for your time. -- Pete

[Dovecot] dovecot and communitgate (stalker)
by tyco 05 Sep '05

05 Sep '05

hi there, i am totally new to dovecot and use communigate pro stalker.com as my mailserver. everything in communigate is fine. the only problem i do have is imap speed. i just got a login at a dovecot server and i must say WOW its so fast amazing. since communigate does not support indexing on mdir direcotries i need to find a solution. so i am wondering if it would be possible to use dovecot imap server on top of communigate as an imap server? i know that this would not work for special cgp features like shared mailboxes. etc.... thnax christof

[Dovecot] Dovecot 1.0 and ldap; does this combination works?
by Vedran Furac 05 Sep '05

05 Sep '05

Hi! After upgrading from dovecot 0.9.14 to 1.0 crashes immediately after starting when using ldap as userdb and passdb. You can find more information here: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=320388 I'm confused with two users: login_user and auth_user. Witch of them has to be in ldap? If anyone here has a working dovecot+ldap configuration, could he show me his configuration? Regards Vedran

[Dovecot] Dovecot-LDA: Development questions
by Steffen Kaiser 05 Sep '05

05 Sep '05

Hello, I'm tinkering with Dovecot-LDA in order to achieve: + Better intergration into sendmail, and + tweaking its way to act on errors. Attached patch is a "brainstorming" like suggestion: a) when sendmail is dropping a message, it spawns the LDA, captures stderr/stdout and, if the LDA returns an exit code != 0, generates either a DSN or, when EX_TEMPFAIL, queues the mail. Hence, it is not necessary to have mail_send_rejection() to spawn another sendmail instance. The attached patch suggest to introduce an "operation_mode", in which Dovecot-LDA behaves differently for different environments. b) Some errors, like when spooling the message into the users folders fails, because the user is out of quota, one should prefer tempfailing the message, rather than a permanent error. Attached patch includes an option "-f", which has main() to return EX_TEMPFAIL. This is the way maildrop is acting, BTW. === Sendmail supports "account+detail" syntax out-of-the-box; that is for recipient matching only the portion left of the plus-sign is significant, the trailing portion may be used by the LDA as a hint to spool the message. Usually the information is passed via command line to the LDA. The libsieve seems to already support this notation, see tokens DETAIL, subaddress, :detail and the README file: Derrick Brashear (shadow+sieve@andrew...) Did somebody used or have some idea how to make use of the "+detail" stuff of libsieve? Basically the main problem in my opinion is what to query, because the information (final physical mailbox and/or owner) one can query is neither a header nor an envelope information (besides that the envelope information is not available to the LDA anyway). Consider a BCC to one recipient that expands to numerous maildrops, then the maildrop of actual delivery attempt can not be derived from neither the envelope nor the header information. The only way to integrate the +detail stuff into Dovecot-LDA seems to be when "keep" is performed (or no Sieve script is present). Then one could spool the message into folder "detail", if it already exists -- one should be allow other people to create mailboxes ;-) This is no action of the Sieve library, but of the LDA calling sieve. The Wiki mentions in the section about to setup exim: envelope_to_add What's this setting is doing? In src/sieve-cmu.c, static int getenvelope, there is: } else if (!strcasecmp(field, "to")) { *contents = m->temp; m->temp[0] = /*FIXME:msg_getrcptall(m, m->cur_rcpt)*/m->authuser; m->temp[1] = NULL; return SIEVE_OK; So it seems appropriate to tweak dovecot_sieve_run() into: mdata.authuser = username; mdata.recipient = detail_on_commandline ? concat(username, "+", detail_on_commandline) : username ; Or better: Have the complete recipient passed via command line option? and alter getenvelope(): m->temp[0] = m->recipient; I think this tweaks would be better than have the "-d" option support the plus-syntax. === Currently, the compiled Sieve script is placed into the same directory the script is located itself. How about to _always_ file the compiled script into [CONTROLDIR]/.dovecot.sievec? That would come over the problem with the system-wide default sieve script. Otherwise: The README mentions a test application and I found a sievec and sieved application (Sieve compile / decompiler) I presume. I can not just run "make sievec" to have it compile, does somebody played around with the Sieve stuff in LDA? Regards, -- Steffen Kaiser

[Dovecot] 1.0a1 Coredumps / errors when moving multiple
by Gregory Bond 05 Sep '05

05 Sep '05

I've just tried upgrading 1.0t51 to 1.0a1 and it has been........ difficult. I've been getting logs of Sig11s and other errors, and have trouble tracking them down. Main problem seems to be with moving / copying messages. One at a time works (mostly), multiple will coredump the imap process (not yet managed to get a proper core out though...) I'm using imap & Maildir, maildir on NFS & Indexes on UFS, Solaris 8. Server is postfix / procmail (delivering pre-sorted into various Maildir folders) and Dovecot 1.0a1. Client is thunderbird on OS/X. If I turn off mbox_copy_with_hardlinks, then instead of a coredump I get a hang and an error message: > IMAP(gnb): Maildir /home/gnb/Maildir sync: UID inserted in the middle > of mailbox (3871 > 3870, file = 1125740849.23189_0.lenford:2,Saa) This is after I've removed all the cache/index files and even all the dovecot-uid files.... I'm back on 1.0t51 for now, but could have another crack at this if there are any hints.

[Dovecot] Dovecot logging
by Black Vette 05 Sep '05

05 Sep '05

Fedora Core 4 dovecot-0.99.14-4.fc4 I'm trying to diagnose some mail issues. I do not believe Dovecot is the problem. If I could see the Dovecot logs, it might be helpful in resolving my issue. In /etc/dovecot.conf I have tried to set the following: log_path = /var/log/dovecot.log info_log_path = /var/log/dovecot.log I have 'touch /var/log/dovecot.log'. When I try to restart dovecot 'service dovecot restart', it fails and I'm not able to see the reason why it is failing. Where am I going wrong getting this working? Also, are there various debug levels? I saw 'debug' mentioned on the list, but I was unable to see anything about it in the config file. Thanks, Mike __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

Re: [Dovecot] qpopper UIDLs and migrating to dovecot/maildir
by Paul Vatta 05 Sep '05

05 Sep '05

Hi Chris, We migrated to Dovecot from Qpopper/UW-IMAP in July. We previously looked at altering the Dovecot code, client-side duplicate email cleanup utilities (for Eudora), and enforcing "download-then-delete from the server" prior to the migration. We got around the "downloading of previously downloaded emails" problem by moving all previously downloaded emails to a new folder called "ConvertedMail" during the conversion process from mbox (Qpopper) to maildir. This assumes you're going to maildir though. The benefit in this is that the POP client only retrieves email from th inbox folder, and after conversion, this will mean only new emails. If the POP client's previous download of older email dissappeared (for whatever reason), a Web Mail client accessing the mailstore via IMAP would allow access to the ConvertedMail folder. Regards, Paul

[Dovecot] login: Missing Protocol from server name 'imap'
by Phil Bettinson 04 Sep '05

04 Sep '05

Hello All (possibly again) I did send a messge earlier, but it may have been eaten by the mail system. I've now managed to get dovecot started, and I'm now getting "Missing protocol from server name 'imap'" This is somewhat confusing. Does it mean that I have somewhere called my server imap? or is it talking about it missing a protocol called imap? if it's meant to be "missing protocol imap definition" or somesuch, I have filled that out, but can't for the life of me figure out what the error message is actually trying to tell me! I'm running dovecot alpha1 on RedHat as3. I have the feeling I've been staring at the problem for too long, and somone will just say "have you tried this!", but it's worth a shot. Thanks in advance Phil

[Dovecot] qpopper UIDLs and migrating to dovecot/maildir
by grant beattie 04 Sep '05

04 Sep '05

hi all, I am hoping to convert a 350K user qpopper installation using mbox to dovecot and maildir (pop3 only). many of the users "leave mail on server", and qpopper's UIDL format isn't (yet) supported by dovecot. since the UIDLs have been written by qpoppper to the existing mbox files (and will be preserved when the mboxes are converted to maildir) it would be possible to do this seamlessly if dovecot could read the UIDLs from the messages and populate the index files as needed. is anything like this already possible? it doesn't matter what UIDLs new messages get, since they would never have been downloaded by the user via qpopper. any ideas would be appreciated. grant.

[Dovecot] Purge / Delete Problem using IMAP
by A Ve 03 Sep '05

03 Sep '05

Hi, I am using dovecot 0.99.14 RPM on a Fedore Core 4 Server. Everything was running fine for weeks (IMAP), and 2 days ago I was not able to delete/purge any Mail in INBOX. I am using Outlook 2003 as an IMAP-Client. I tried to delete/purge the Inbox with other mail-clients (Mozilla Thunderbird, Mulberry) too, same effect: I can read mail, I can copy them by drag-n-drop to a local Client-Folder (eg: Outlook) , but I can delete them. Strange enough, the mails are marked as read, but when I login again, all Mail are marked as new/unread ! When I log to the node, and start mutt (which is using the spool-file /var/spool/mail/username), then I am able to read-n-delete all Mails... The File Permisson of the File: 755, Owner: Username, Group: Mail. Did I miss something ? How can this stop working from one day to another ? I seems to me, like the INBOX is not writable to me ... From the UNIX Side, it is ... :-/ Any Comment/Feedback would be helpfull. This is really strange. Regards, AVE.

[Dovecot] Weird internaldate behavior with 1.0-test80 and mbox folder
by Jon Roma 03 Sep '05

03 Sep '05

Has anyone else encountered weird date behavior with mbox-style folders? I am nearly ready to bite the bullet and convert my UW imap hierarchy (which is in mbx format) to Dovecot. In so doing, I need to convert each UW-specific mbx-format mailboxes to the more portable mbox format, which Dovecot can read. (This is done with the 'mbxcvt' utility that's part of UW.) I am then planning to copy those mbox-format folders into a staging area in a directory I've defined to Dovecot as a mbox-format namespace. The plan was then to use my normal GUI to reorganize my old data and copy it into proper maildir folders into Dovecot's default namespace. Since I'm naturally paranoid, I did a dry run of a couple folders first and discovered a rather strange anomaly -- all the mail in the converted folder is displayed by Dovecot with a timestamp exactly 200 minutes (3 hours 20 minutes) into the future! Investigating this via telneting to the respective IMAP ports shows that UW imapd shows the correct timestamp both in the original mbx-format folder and the converted mbox-format folder -- so it appears that Dovecot is skewing the time. This doesn't look like a timezone issue since 200 minutes ahead from CST6CDT would be a pretty strange timezone -- not even Newfoundland has this odd a TZ value! :) (For the curious, Newfoundland is a Canadian province whose time zone is TZ=NST3:30NDT, therefore being a half-hour "off" from the rest of North America.) I have distilled this into a degenerate case of a single folder with a single message and can reproduce. As mentioned, I am running 1.0-test80. My platform is AIX 5.1. I created the test by sending a message to myself using date | mail -s "Test at $(date)" roma(a)uiuc.edu and using my MUA (Mulberry) to file it into the test folder, which defaults to mbx format in UW's namespace. Here's what UW shows when I select/fetch the "original" message: * namespace * NAMESPACE (("" "/")("#mhinbox" NIL)("#mh/" "/")) (("~" "/")) (("#shared/" "/")("#ftp/" "/")("#news."

Notice the "internaldate" response. Dovecot reports the correct time zone, but the internaldate value is 200 minutes ahead of what it should be!!! This is an interesting mystery; I seem to be living three hours and 20 minutes in the future. I've attached the entire contents of the mbox-style mailbox that Dovecot misinterprets.

[Dovecot] (no subject)
by Phillip Needham 02 Sep '05

02 Sep '05

I am trying to get away from courier imap because it is flaky the way it uses FAM (or gamin in my case), and the developers seem to have a chip on their collective shoulder, and it is too complex. I found dovecot because it is ships with CentOS 4 (ie Red Hat Enterprise 4). It looks like just what I need: simple, fast. But I can't use it! I can't authenticate. If any of these statements were untrue, I would use it happily: o it doesn't support simple bind authentication against LDAP o I don't want to make passwords readable, and this version (0.99.14) doesn't support SSHA anyway o it won't talk to the saslauthd I already have configured o I can't find how to implement a new auth module for dovecot I am wondering why, in the quest to fill a niche with a simple, fast, secure IMAP server, the authors felt the need to re-implement a robust and well-tested infrastructure (saslauthd) with a less-featureful and untested one?

[Dovecot] Dovecot imap with Postfix and using Thunderbird as client
by Ben Ware 02 Sep '05

02 Sep '05

Hi, I just recently installed dovecot, and I am having the following problem: If I send an email to my account on this new machine, I can log in via SSH and use the unix mail command, and instantly my email is visible. If I turn on Thunderbird, it will show my new message. If Thunderbird was already on and had already checked the mailbox, even if I click on get new mail for that specific mailbox, the new mail does not show up until I restart thunderbird. Is there something that I have set wrong in the config files that is preventing the IMAP part of dovecot from refreshing the messages quickly for me to see? I dont see anything in the log files at all except for it showing me logging in. Thanks, Ben

[Dovecot] 'Bind'-method authentication for LDAP
by Phillip Needham 02 Sep '05

02 Sep '05

Has there been any thought given to implementing authentication via an LDAP 'bind', rather than by a password lookup and hash comparison? doing a bind would obviate the need to make the passwords readable by the dovecot process and would lend itself to improved security.

Re: [Dovecot] Oddities with Debian unstable dovecot

whaooo that is interesting, Thank you so much for the explanation. I guess my choice now is to go with maildir as Blairpoint out because I am running in single host mode. Probably in the future I will run a big enough enviroment as a cluster data center them I will op for mbox. Thank you again Blair and Tomi for educating me in the topic.Lisandro ----------------------------------------------------------------------------------------------------------------------- Lisandro Grullon New York City College of Technology Division of Continuing Education Director of Network Operations Lisandro Office: 1718-552-1178 Lisandro E-mail: lgrullon(a)citytech.cuny.edu "Unix is user-friendly.

Thanks. I'd say it depends, I'm working with clustered filesystems in SAN environments where mbox is significantly faster than maildir since single mbox file generates much less overhead in form of distributed file locking accross cluster nodes. On single host systems with good file system I'd probably go with maildir. Maybe someday I'll manage to do some benchmarking between mbox and maildir with Dovecot. -- Tomi Hakala

Lisandro Grullon wrote: > What method for mail boxes are you guys using mbox or maildir and which one would you recommend? Thanks. I use maildir because it stores each message in a separate file. So this gets me: 1) Daily backups of a ~/Maildir are much smaller than a large mbox because most files don't change, while a single change to a large mbox file will require the entire mbox to be backed up. 2) Moving emails from folder to folder is much faster, as it's moving a single file and you don't have to delete an email from a middle of a mbox file. I have a 5 year old 450 Mhz Dell that easily and quickly manages over 2 Gbytes of email for several users. Regards, Blair
