[Dovecot] Performance Tuning Recommendations for Dovecot
by Jack Stewart 04 Dec '06

04 Dec '06

Hi, I'm wondering if anyone has some performance tuning recommendations for Dovecot. We are currently building a series of department e-mail/imap servers and we will be replacing our central core in the coming summer. The department servers are relatively small 100-200 users and the central server is modest - around 7000 accounts. They will be using local filesystem or SAN for the backend storage. So far, enabling hard links seems to be a big win. I'm curious if there are others out there that people have found useful. I am considering putting the indexes on memory disks but I haven't scoped out the requirements for the central system yet (i.e. it is unclear to me how large the index will be for approximately 13 million messages take take up roughly 800GB of disk space. Any pointers are greatly appreciated. Sincerely, ---Jack Stewart

[Dovecot] Deliver bounces messages if can't write to logs
by Francisco Reyes 04 Dec '06

04 Dec '06

I am new to using Dovecot's LDA deliver. One particular item which I think may be improved.. If one uses logs instead of syslog and if Dovecot/Deliver can't write to the logs, mail is bounced. In contrast if it can't connect to the authentication socket auth-master, it defers. Shouldn't mail be deferred if access to the log files fails due to rights? Doesn defer makes more sense than to bounce in this case? In all likelihood it was postfix that bounced/deferred, but I believe it has to do with what response postfix got from deliver.

[Dovecot] Enabling different quota limits for different users for /etc/passwd as userdatabase on FC3
by ankush grover 04 Dec '06

04 Dec '06

hey friends, I am running my company's mail server on FC3 which comprises of Postfix + Dovecot + MailScanner + Clamav + Squirrelmail + MailWatch + Spamassassin. I am using Dovecot 0.99.13-3 version on FC3 and I want to implement Quota limits for the users. I am using userdatabase as /etc/passwd file (auth_userdb = passwd ) and password database as pam(auth_passdb = pam) for dovecot. I read the documentation of dovecot but the quota example for /etc/passwd is missing. I want to have different quota limits for different users for example Quota limitation will depend upon the users, well there will be a global quota limit which will takes place if there is no limit specified for that particular user. Can anybody guide me how to configure quota's for different users in dovecot for /etc/passwd as userdatabase and pam as password database. Please let me know if you need any further inputs. Thanks & Regards Ankush Grover

[Dovecot] Protecting folders

[Dovecot] / and . in folder names
by Magnus Holmgren 03 Dec '06

03 Dec '06

Right now, trying to create folders with "/" or "." in their name can yield strange results, because Dovecot simply turns every occurrence of the current folder hierarchy separator in a folder name given by the client into a "." (or so it seems). If the folder separator isn't ".", clients can try to create folders with names containing ".", and Dovecot will convert those "." back to the folder separator on listing. It will look like there is an intermediate folder, but Dovecot is unaware of it. If the folder separator isn't "/", clients can try to create folders with names containing "/", which will simply fail. Judging from to http://www.courier-mta.org/?maildir.html, Courier encodes "." and "/" in the names of the directories the folders are stored as on disk. This means that that of "." and "/" that isn't the folder separator can be used in folder names, but it also means that Dovecot has to be able to perform the recoding. Has any thought been given to this? -- Magnus Holmgren holmgren(a)lysator.liu.se (No Cc of list mail needed, thanks) "Exim is better at being younger, whereas sendmail is better for Scrabble (50 point bonus for clearing your rack)" -- Dave Evans

Hi Everyone, I have been recently getting these errors in Evolution 2.6.1.

[Dovecot] Deliver Root Setuid
by Láďa 03 Dec '06

03 Dec '06

Hi, I just configured my Postfix installation to deliver via Dovecot LDA. But because I use separate uids for virtual domains I had to set deliver to be setuid root. Altough I find this as frequent answer to this problem with deliver LDA I am not a 100% sure - basically because I try to avoid root setuids as much as I can. What should be better solution - to have all mailboxes with one owner or this setuid binary? My main reason for separate uids was filesystem quotas for whole domain. But my mail partition resides on XFS so I can do the same with directory quotas and I also noticed changes in quotas which should be also per domain in some next release or with patch. Thanks for any advice and also thanks for all great work on Dovecot. Láďa

[Dovecot] [IDEA] Shared Folders via LDAP Lookups
by Gavin Henry 03 Dec '06

03 Dec '06

Hi All, We've been thinking a lot about the 2 different ways dovecot implements shares; namespaces and symlinks. We currently use the symlink version for our clients and they use the create_dovecot_shares.pl tool we did at: http://dovecot.org/tools/ Our idea is either in the namespace declaration or if a folder has a dovecot-shared file/symlink, have a ldap lookup defined in say, dovecot-ldap-shares.conf or dovecot-ldap.conf, that queries a dn and looks for memberUID or a group dn, then those uids/groups can get into the IMAP maildir. Obviously the original folder would need to be owned by some predefined user, e.g dovecot etc. Then it's just a simple matter of adding a new memberUID/group to the share listing. We can do a custom dovecot.schema if needed (for say a dovecotShare attribute etc.), as long as we get dovecot a Private Enterprise Number from: http://www.iana.org/cgi-bin/enterprise.pl If Timo hasn't already got one, but I can't see one in: http://www.iana.org/assignments/enterprise-numbers Thoughts? -- Kind Regards, Gavin Henry.

[Dovecot] small mbox and index files problem
by Paul Shackel 03 Dec '06

03 Dec '06

Dovecot version: 1.0-0_33.rc15 built by atrpms Operating system: Redhat EL4 CPU architecture: x86 Filesystem you used: mailboxs via nfs to fileserver using xfs Just upgraded from 1.0-0_20.rc7 to 1.0-0_33.rc15 built by atrpms and we had previously set mbox_min_index_size to 1024 (1Mb) and now all mailboxes (mbox format) that are under this size are not able to be opened and throw an "Internal error occured. Refer to server log for more information." using either Thunderbird or Outlook Express, both of which are recent versions. The small mailboxes can be opened after turning mbox_min_index_size setting back to 0, at which time it creates indexes. There is nothing in the syslog file. I am looking in the right place as I can see the dovecot startup message. paul --

Re: [Dovecot] dovecot:IMAP(user) killed with signal 6
by Spil Oss 03 Dec '06

03 Dec '06

Thanks Timo! Since I've been running rc10 again dovecot stopped aborting. By the way, when I used the create_shares.pl script, it created a symlink for every file in the directory to be shared. Simple symlinking the dir seemed to 'almost' work but for the keyword file errors. Upgrading to rc15 fixes the problem as well, the Permission Denied message still comes up, but dovecot no longer aborts. Will try the create_shares.pl script again and see where my symlink-config is wrong. FWIW I wouldn't want any undocumented behaviour in dovecot just because I'm a stupid twat... Kind regards, Spil.

[Dovecot] Problem with rc10, perhaps 11-15
by Steven F Siirila 03 Dec '06

03 Dec '06

I don't recall if I mentioned this on the list, but when you are configured with mbox format, and a user has no Dovecot index files yet, and the config is such that mbox_min_index_size is set to non-zero, non-default (128 in my test case), dovecot deliver fails. Commenting out "mbox_min_index_size" fixed the problem, and the indexes then get created. This problems exists in RC10 -- I'm mentioned this in case it still exists in the latest revs so it can get fixed before release. -- Steven F.

[Dovecot] IMAPS works, IMAP does not
by Peter Lindgren 03 Dec '06

03 Dec '06

Hello! I have a simple (I think) problem. I have had IMAPS working fine for a long time. Now I want to start to use IMAP and STARTLS, since my mobile SonyEricsson P900 can't use IMAPS directly. But I can't connect even locally to the IMAP port (143), no-one listens there according to netstat (*.imaps is in LISTEN state). I have the following settings in my /etc/dovecot.conf: protocols = imap imaps ssl_cert_file = /etc/ssl/dovecotcert.pem ssl_key_file = /etc/ssl/private/dovecot.pem disable_plaintext_auth = no login_user = _dovecot login_greeting = Dovecot@casiopea ready. mail_read_mmaped = yes mmap_no_write = no protocol imap { login_greeting_capability = yes } protocol pop3 { } auth_verbose = yes auth default { mechanisms = cram-md5 digest-md5 passdb passwd { } userdb passwd { } user = root } I have restarted (SIGTERM) dovecot to be sure that dovecot is restarted. I still run 1.0beta3 on OpenBSD. TIA, Peter -- Peter Lindgren, dataingenjör E-post: peter "at" norrskenkonsult punkt com http://www.norrskenkonsult.com

[Dovecot] shared folder
by T. Horsnell 03 Dec '06

03 Dec '06

The dovecot wiki says: The only way to implement shared folders with Dovecot 0.99.x is to create a "shared userid" which all of the users log in to read mail. Does this mean that folders owned by that shared uid can be *simultaneously* manipulated by multiple users logged in to that shared uid? This doesnt seem to be the case on my dovecot-0.99.11-4.EL4 system, and before investigating further I just wanted to check whether it should be possible or not. Cheers, Terry.

[Dovecot] Nested folders in FS supported yet?
by Sweth Chandramouli 03 Dec '06

03 Dec '06

The last time I checked, dovecot didn't support having nested IMAP folders be implemented via actual nested maildir folders in the filesystem, but that feature was on the "someday maybe it'll happen list", IIRC. I can't find any recent mention of that feature or its absence on the web or in the list archives; is it still on the someday list? (If it isn't implemented yet, does anyone know of an IMAP server that DOES support it?) Thanks, Sweth. -- Sweth Chandramouli sweth(a)ethicalhomes.com - http://EthicalHomes.com/ Thinking about buying a home, but feel like the local real estate market has left you behind?

[Dovecot] Can't remove folder
by Leroy van Logchem 03 Dec '06

03 Dec '06

Hello, Here is a 'me too' somewhat like: http://www.dovecot.org/list/dovecot/2006-January/010759.html Example scenario: /u/username/Mail/subfolder/somebox subfolder is a directory somebox is a mbox When I use Thunderbird's "Delete folder" function on the somebox the message appears: "Target mailbox doesn't allow inferiour mailboxes". Thunderbird, by default, tries to move it to Trash instead of deleting it directly. When I change the preference to "Remove it immediately" it works. Which component is at fault here: - limitation of a mbox only setup? - thunderbird should know - limitation of the imap protocol to advice the client it's mbox backed - feature of dovecot, could it be fixed or worked around somehow -- Leroy

[Dovecot] Logging
by Steven F Siirila 03 Dec '06

03 Dec '06

In trying to determine why someone was unable to use port 110 w/STLS (POP) I had great difficulty finding the session in which the user switched to this port from using port 995. This is because Dovecot does not log any port number information. Furthermore, it isn't obvious to me if it logs whether a session was negotiated SSL (via STARTTLS w/IMAP or STLS w/POP) or started out SSL (ports 993 and 995). If this seems reasonable, I can whip up a patch to log this information. However, I'd rather see Dovecot 1.0 released first. -- Steven F.

[Dovecot] authentication
by eric 03 Dec '06

03 Dec '06

Good evening from Aotearoa; First some details: Clients are all Outlook2003 on XP yawn Server is Suse 9.3 Samba, postfix, fetchmail and dovecot 1.0 rc13 I succesfully installed Dovecot on my test network at home, but at the job site its a mystery. I seem to be able to get one client to authenticate but not another. And only if i created a password file consisting of logins and no passwords. Dovecot won't use standard unix passwd successfully.

[Dovecot] method= in log file

In Dovecot log I have: Nov 30 20:35:16 xx dovecot: pop3-login: Login: user=<xxx>, method=PLAIN, rip=x.x.x.102, lip=y.y.y.53 Nov 30 20:35:16 xx dovecot: imap-login: Login: user=<xxx>, method=plain, rip=x.x.x.102, lip=y.y.y.53 Apart the protocol (IMAP and POP3) is there a difference between "method=PLAIN" and "method=plain"?

[Dovecot] Problems using Squirrelmail / Dovecot / Sendmail / Fedora Core 6 - ERROR: Connection dropped by IMAP server
by Alexander Lapajne 03 Dec '06

03 Dec '06

Hello I just installed Fedora Core 6 and I'm having problems with SquirrelMail. I'm using Squirrelmail/Dovecot/Sendmail and when I log into Squirrelmail and try to view any folder that contains any messages I get: ERROR: Connection dropped by IMAP server. Query: SORT (ARRIVAL) ISO-8859-1 ALL Now, I've tried to disable server side sorting in Squirrelmail but that only leads to a new error message: ERROR: Connection dropped by IMAP server. Query: FETCH 1:* (FLAGS UID RFC822.SIZE INTERNALDATE BODY.PEEK[HEADER.FIELDS (Date To Cc From Subject X-Priority Importance Priority Content-Type)]) I'm using the default setup and POP3 mail is working. Using Thunderbird I can read email using POP3. So the problem only appears when using Squirrelmail. I had the exact same setup in Fedora Core 5 and it was working perfectly. Same config files and everything. _________________________________________________________ Flyger tiden iväg? Fånga dagen med Yahoo! Mails inbyggda kalender.

Re: [Dovecot] POP3 protection
by Jos Chrispijn 03 Dec '06

03 Dec '06

Odhiambo WASHINGTON: > Use a database and create an imap_enable field that is 1 if enabled and > 0 if disabled and use this condition in the query. Actually I am suggesting to let go SQL only for that and do it with a simple, plain text solution from within the configuration file. That can't be that difficult can it? It Postfix can do stuff with sender_checks and client_checks why using a database for a simple 0 or 1 :-) thanks for your reply, Floor

[Dovecot] %s service variable substitution
by Jim Horner 01 Dec '06

01 Dec '06

I'm using 1.0rc15. We switched over to using deliver LDA and using dovecot's sasl implementation for postfix... In our ldap configuration we were using (similar for password filter) user_filter = (&(objectClass=mailUser)(mail=%u)(mailSettingValue=%s)) The problem is these new services, namely deliver and postfix, are accessing the authentication mechanisms and I am not sure what to put in ldap so the %s can match. Each user currently only has a mailSettingValue=IMAP. This can be expanded for multiple entries. Thanks, Jim

[Dovecot] Quota's with Thunderbird
by Richard Mayhew - Nashua Mobile Broadband Division 30 Nov '06

30 Nov '06

Hi, Does anyone know how to get Thunderbird to correctly report the mailbox quota's? I know Dovecot is correctly enforcing the quotas on the mailbox when using Thunderbird, but Thunderbird reports that the "server does not support quota's" when trying to view the usage? Is Thunderbird expecting something different? Viewing the mailbox through Squirelmail, the quota's are reported correctly, so I would thnk that Thunderbird is where the problem lies. Regards Richard

[Dovecot] lmtp: help needed
by Leonardo Lanzi 29 Nov '06

29 Nov '06

Hi all, parsing the mailing list archive, it seems that the lmtp-server will not be developed soon, so I'm looking for someone that could help me in writing one, even if not the best one. That's why: I've just started to study dovecot, as I was recruited, just about forced, to help The System Manager of our University in the global e-mail migration - more than 37'000 users, 440 mailing lists, everything synchronized with administrative databases and so on - from open-vms (yes... you have not sight problems: OpenVMS ... please don't blame us). In particular, we have (we'd like so much) to directly deliver from a front-end load-balanced anti-spam&virus all "good" messages into maildirs, updating at the same time the indexes for dovecot. Our idea is to write an lmtp, possibly not from scratch; we have already a threaded server, recently born as a raw smtp server to test the antivirus and antispam system under heavy load (before to start the migration), that can be converted to lmtp protocol, but we lack of information on the dovecot API for delivering in a "dovecot-way". As often occurs, we have not months to get it done, therefore _any_ kind of suggestion will be very much appreciated. Thank you all for the help, and patience! -- Leonardo Lanzi Department of Physics - University of Florence - Italy -- PS - Examples of help: 1. "The code is self-explaining, but obviously you're too old to learn: accept to be in the mist, and switch to cyrus" 2. "the following n-functions ... of deliver can accept your data from memory and do all the job" 3. "I've already done everything, download it at the following url..." 3a. "I've already done everything, but you must send me, _before_, your smtp stressing server, or all your tests on latency of irq handlers with 2.6 kernel, or at least one 18-year-old scottish-malt-whisky bottle!"

[Dovecot] Subfolders with Thunderbird and maildir?
by Andrew Z 29 Nov '06

29 Nov '06

I setup a test dovecot-1.0-0.beta8.2.fc5 and left most of the settings as the defaults. In Thunderbird 1.5.0.8 Windows, when I tried to create a subfolder named "subfolder" under INBOX, it showed up as the same level a INBOX and with the name "INBOX^subfolder". I was able to manually create a subfolder using "mkdir ~/mail/test_manual_subfolder; touch ~/mail_test_subfolder/blah" and then subscribing to it. That's too much work. :) Now when I try to create a subfolder of a non-inbox folder, nothing happens (not even an error). Screen shot: http://img452.imageshack.us/my.php?image=subfoldersthunderbird15ao6.png The Dovecot system is Fedora Core 5 x86 and an NFS client for /home. I'm considering switching from Trustix, UW-IMAP, and mbox. I'm also considering changing INBOX to a Maildir (not /var/spool/mail/%u). Andrew
