[Dovecot] quota percents
by Micah Anderson 13 Sep '11

13 Sep '11

I've noticed that http://wiki2.dovecot.org/Quota/Configuration is out of date, it says: plugin { quota = maildir:User quota quota_rule = *:storage=1GB # 10% of 1GB = 100MB quota_rule2 = Trash:storage=10%% # 20% of 1GB = 200MB quota_rule3 = Spam:storage=20%% } but if you use the '10%%' notation, dovecot complains, and *also* incorrectly: dovecot: imap(test(a)example.net): Warning: quota root mail quota rule Trash:bytes=10%: obsolete configuration for rule 'bytes=10%' should be changed to 'bytes=+10%' its incorrect because if you change it to what it suggests ('+10%') it wont work because that wont be 10% more, rather, it is set to bytes=+10: dovecot: imap(test(a)example.net): Debug: Quota rule: root=mail quota mailbox=Trash bytes=+10 messages=0 clearly, that isn't right... so I guess it needs to be changed to '+10%%', setting that provides: dovecot: imap(test(a)example.net): Debug: Quota rule: root=mail quota mailbox=* bytes=2211724 messages=0 dovecot: imap(test(a)example.net): Debug: Quota rule: root=mail quota mailbox=Trash bytes=+221172 (10%) messages=0 that seems ok, its saying the Trash mailbox is set to have 221172bytes (215 kilobytes) of quota. So, clearly http://wiki2.dovecot.org/Quota/Configuration needs to be updated. However, it doesn't seem to work in practice, because I have a user that is at 99% of quota, with nothing in the Trash who cannot move a 77KB message into the Trash without getting the quota_exceeded message and refusing to move it. so... how do I get this to work? thanks! micah --

[Dovecot] Migrating a dovecot setup from one server to another
by James Carr 13 Sep '11

13 Sep '11

Hi All, I have a server with a dovecot + postfix setup and unfortunately the server is EOL'd. I have built a new ubuntu server out and I'm in the process of migrating everything over. In migrating the dovecot setup over, this is the list of items I have done: install dovecot, postfix, etc on the new server copy configuration files over copy /var/spool and /var/mail over Is there anything else I need to consider before switching MX records to point to the new server? Thanks, James

[Dovecot] imapc and imap_acl
by Lutz Preßler 13 Sep '11

13 Sep '11

Hello (Timo), yes, I know... maybe it's a bit far fetched, but I do have a use case. Would it be (reasonably easily) possible to implement IMAP ACL support for "imported" imapc namespaces/mailboxes? There is no local directory (like with the virtual plugin) yet...

[Dovecot] Dovecot and Lustre FS
by Christian Gregoire 13 Sep '11

13 Sep '11

Hello, Right now, I'm using Exim and a customized version of an old (10 years old) Atmail POP3 server written in Perl, with ~10000 mailboxes located on a Lustre file system. So far so good. Though, I plan to migrate from Atmail to Dovecot, to provide our customers with IMAP support. Has anyone any experience with Dovecot on Lustre FS ? Thanks Christian

[Dovecot] Problem with configuring dovecot to take namespaces from database
by Marcin Mirosław 13 Sep '11

13 Sep '11

Hello! I'd like to set up dovecot to keep namespaces in database, keep more than one namespace per user. I try to create the simplest rule (even without tuple in db table) to get new namespace, unfortunately it doesn't work. My user_query is: SELECT '/dane/domeny/%d/mail/%n/' as home, dovecot_typ_skrzynki ||':'|| '/dane/domeny/%d/mail/%n/' ||'.'|| dovecot_typ_skrzynki as mail_location, '*:bytes='||quota_mb||'M' as quota_rule , 'test33/location=mdbox:~/.mdbox/test33/' as "namespace/test3/prefix" In debug log i'm getting: Debug: master out: USER#0111#011user@examle.com#011home=/dane/domeny/mejor.pl/mail/marcin/#011mail_location=maildir:/dane/domeny/mejor.pl/mail/marcin/.maildir#011quota_rule=*:bytes=0M#011namespace/test3/prefix=test33/location=mdbox:~/.mdbox/test33/ If i knew how it should look like the line in auth debug log for working configuration it could be easier for me to write correct sql query. May i please for advice?

[Dovecot] MySQL, map files
by Steve Fatula 13 Sep '11

13 Sep '11

I'll try and break up my questions the other day about extdata that went unanswered into pieces in the hopes it will be more specific and clear. In general, I am trying to figure out the syntax of the map statement and what is allowed in that statement. So, by map statement, I mean for example perhaps the dovecot-dict-expire.conf.ext file as shown in the doc. Is the syntax the same for the various types of files (quota vs expire)? Is there syntax to allow the specification of a different key? If so, where is this documented. I have an existing table I want to use, not the table shown in the doc. The reason I am asking is I have seen web pages that reference all sorts of statements within the map statement, and I have no idea where they are documented. Specifically, I see an example here (which is LDAP), look in section 3: http://dovecot.org/patches/1.2/ldap/HOWTO_dictldap+extdata.txt You will see lots of statements, not sure which ones can be used for MySQL (instead of LDAP). So, would like to find a list of ALL valid syntax within the map.

[Dovecot] director ignoring director_mail_servers for lmtp connections
by mailing lists 13 Sep '11

Hello, Following Jan-Frode's advise I am trying this configuration: {postfix} ---lmtp---> {director} ---lmtp---> {dovecot} so I have two dovecot instances for director/proxy and lmtp delivery on ports 1024 and 24 respectively. whilst for imap connections I can specify a pool of imap backend servers via 'director_mail_servers' it seems is not possible with lmtp.

[Dovecot] signal 11 crash, sometimes, during mbox bz2 decompression
by Mike Brown 13 Sep '11

13 Sep '11

Hello again, I'm running dovecot 1.2.16 from the ports collection on FreeBSD 8.1-STABLE, amd64. To enable IMAP read-only access to gzip or bzip2 compressed mbox files, I added the following to my dovecot.conf, in the protocol imap { ... } section: mail_plugins = zlib My compressed mbox files are all .bz2 files in an 'old' subdirectory of my main mail directory. I am trying to access them with Thunderbird. I 'subscribed' to them just fine, and at first I thought it was working, but I just got lucky on the first couple I accessed. Dovecot actually fails to decompress them about 90% of the time, seemingly at random; the same box will not work a bunch of times, then work once, then not work again and again. When it works, sometimes only some of the messages get transmitted. Most of the failures are accompanied by this pair of messages in my log: Aug 16 00:25:33 myhost dovecot: dovecot: child 943 (imap) killed with signal 11 (core not dumped - set mail_drop_priv_before_exec=yes) Aug 16 00:25:33 myhost kernel: pid 943 (imap), uid 1001: exited on signal 11 Some of the failures have only the "exited on signal 11" message. The very first failure had this: Aug 16 00:22:47 myhost dovecot: IMAP(mike): Next message unexpectedly lost from mbox file (read-only mbox stream) at 2761 (cached) Aug 16 00:22:47 myhost dovecot: IMAP(mike): read(mail, uid=2) failed: Invalid argument Is this a problem with dovecot? Let me know if/how I can help, or what other info you need. Thanks, Mike

[Dovecot] Custom error messages.

I am using Dovecot 1.2.9. Is it possible to have custom error messages? I want to translate some of the messages (for instance mailbox full), so it can be more user friendly. I already use the quota warning feature. But I need to translate the messages anyways, is it possible? Lauro

[Dovecot] Possible to Customize File Naming Scheme?
by Dave Stubbs 12 Sep '11

12 Sep '11

Hello all, [Sorry if this has been covered already - I searched back a little way in the archive and didn't find anything recent on the topic.] I'm wondering if it is possible to customize the way dovecot creates or modifies filenames in the maildir directories? I'm watching how my mail system works, and I see that procmail creates a new file in the <folder>/new directory, each time an email is received. This file is some complex combination of UIDs and things, suffixed by the server name. So far, the filename has alphanumerics, a couple underscores, and a dot or two only. But once dovecot gets it's hands on the file and moves it to the <folder>/cur directory, it starts doing "terrible" things to the file name. Now, the filename starts to have "evil" things in it, like colons and commas. Is there a way to change this? I'm asking this primarily because I use dovecot as a massive long-term email archiving system. One of the things one needs to be able to do when running a long-term archive like this is keep things as simple and accessible as possible. The reason I use maildir is that I totally buy into the "one email, one file" idea - it means I don't have to store messages in big consolidated database files that are changeable with each new version of the vendor's software release (such as exchange DBs or Outlook PST files) or that are horrible performers (such as mbox). One of the nice things about the maildir "each email is a separate file" idea is that you are not limited to maildir or dovecot or any other piece of software to handle, read, and process the files. For instance, I would like to backup my maildir by using rsync to synchronize my dovecot-managed maildir to a Windows server running NFS. From there the files are synchronized via Windows DFS ( to which there is no open source solution that is even close) to several other servers around the continent. Only thing: The evil commas and colons in the filenames are anathema to Windows. So instead I tar the maildir folders to tgz files on the windows server, and the tgz's are synchronized to other DR sites. If I could do without the need for tar (mandated solely because of the colons and commas in the dovecot filename scheme) I could minimize the time to backup (only synchronizing changes) and suddenly I would have a lot of other benefits opened up. One simple one would be that if I could configure dovecot to append the .eml extension to the end of every file (technically each file in a maildir is an eml file regardless of the extension being present or not - eml is just a raw mail file just like what you'd find in a maildir) I would have instant access to them using Search Server Express, which can read eml files but strongly prefers to use extentions to recognize files as such. To be clear: I'm not requesting that dovecot's file naming convention be changed to match my quirky requirements - I'm just asking if it could be made configurable, so I could change it to match my needs and others could change it to match theirs. In the interests of REALLY being able to use the elegantly simple idea of each mail being a separate file, I'm trying to get more out of that great pile of folders and files I'm amassing in my mail archive server. The more use I can make of them with other software other than dovecot (i.e. data crawling, indexing, easy recovery in a catastrophe, etc) the more valuable this format is. Is this possible?

[Dovecot] userdb static & Quota from LDAP?
by Christian Schmidt 12 Sep '11

12 Sep '11

Hi all, I just configured Dovecot 2.0.14 for "virtual" (i.e. non-system-) users: passdb { driver = ldap args = /etc/dovecot/conf.d/ldap-passdb.ext } userdb { driver = static args = uid=vmail gid=vmail home=/var/maildir/%u } Works fine so far - thanks for this great piece of software, Timo!!! Now I'd like to add per-user quotas that will also be stored in the LDAP directory, and I'm not sure how to put things together. IMHO quota is the only "userdb information" requested from LDAP, and I'd like to leave all the other "userdb pieces" as the are. I changed the userdb definition to: userdb { driver = ldap args = /etc/dovecot/conf.d/ldap-userdb.ext } My /etc/dovecot/conf.d/ldap-userdb.ext contains (along other lines): user_attrs = uid=vmail,gid=vmail,home=/var/maildir/%u,mailQuota=quota=quota_rule=*:storage=%$ My quota configuration looks like this: plugin { quota = maildir:Mailbox-Quota quota_rule = *:storage=1G quota_warning = storage=80%% /usr/local/bin/quotawarn.sh 80 %u quota_warning2 = storage=95%% /usr/local/bin/quotawarn.sh 95 %u } Using this setup, "doveadm quota get -u username" doesn't reveal any quota information (except from the "headings"). Instead, dovecot logs: doveadm(username): Fatal: GID 0 isn't permitted When switching back to userdb static, I receive the correct (but also) static quota information. What am I doing wrong? Thank you very much, Christian Schmidt -- question = ( to ) ? be : ! be; -- Wm. Shakespeare

Also do you see anything in error logs? If you're using the default pop3_uidl_format it'll rely on IMAP UIDs to stay the same, and I guess it's possible that due to some other problem they change (that should be logged as an error/warning though). You could try setting pop3_uidl_format=%f, but it will cause everyone to redownload mails. With newer Dovecot versions you could set pop3_save_uidl=yes and when you think everyone's downloaded mails once you can safely change the pop3_uidl_format.

[Dovecot] Dsync and hidden files
by Dick Middleton 12 Sep '11

12 Sep '11

Hi, I'm in the process of changing from Dovecot v1 to v2 and changing to mdbox in the process. I've come across a little problem which I was hoping there would be a workaround for. There are sieve config files in the home directories which are hidden files. Dsync croaks when it finds one of these because they are not mbox format. It would be nice if they were ignored (or copied unchanged). Is there another way to deal with them other than by deleting thm? Dick

[Dovecot] general advice sought
by Alan Brown 12 Sep '11

12 Sep '11

I'd like to hear the thoughts of list members on which type of storage method seems "best" for inboxes and for folders. The filesystem is GFS2 and for various reasons I can't change it. Inboxes - currently Mbox format. Some users have upwards of 5000 messages in there (the largest is about 18k entries) and thanks to attachments some inboxes are 40-200Mb with a few sitting at 2-3Gb. (Suicidal, I know but enforcing rules is politik-laden and getting academics to behave sensibly is like herding cats) Folders: Mdir format. Thanks to GFS2 filesystem limitations(*) I'm currently enforcing a limit of 4000 messages/folder. It'd be nice to have a "better" way of storing these which doesn't drive up backup loads tremendously. The mail spool has around 6 million files in the folders, covering about 400Gb. GFS2 filesystem limitations are painful. While there are no hard limits, It really doesn't cope well with a lot of files in any given directory thanks to limitations in the way that cluster locking is propagated, There are marked slowdowns about 100 files, this becomes awful above 1000 and effectively unusable above about 8000 entries as the entire IO system gets halted momentarily when such directories are opened and the directory may take up to 5 minutes to return a "ls" result. Some users had upwards of 80k files in their mail folders (~40k messages) and accessing these brought the entire system to a halt. If I migrate to other formats (eg mdbox), then it needs to be able to be done on the fly. (Taking the mailservers down for a day won't go down well, even an hour raises howls). Any suggestions?

For the Gmail mailboxe the INBOX.gmail prefix is missing and / is used as separator.

[Dovecot] Read-only mbox files
by Tim Bishop 12 Sep '11

12 Sep '11

Hi all, I'm using Dovecot 1.2.16 (I can upgrade to 2.0 if need be) and I'm having trouble stopping Dovecot from modifying mbox files. The setup is that my main namespace points at my Maildir mail folders. In addition to this I have a second namespace that points at some old archived mbox folders. I rarely need to access these folders, but when I do Dovecot modifies the files (adding UID headers, etc). What I'd like to do is make it so that Dovecot can't change these files. I thought there might be a setting to mark a mail_location as read-only, but I can't find anything like that. I've looked at ACLs too, but they seem to be more about user access that what Dovecot can do to files. I could just do this at the filesystem level, but I'd feel a bit happier about working with Dovecot rather than trying to work around it. Does anyone have any suggestions? Thank you for reading.

[Dovecot] sieve and pattern matching
by David Newman 11 Sep '11

11 Sep '11

Dovecot 1.2.17 What is the sieve syntax for matching text somewhere in a subject line, but not at the beginning of the line? Background: Multiple machines each send a message with the subject of "<hostname> operations run" to a mail server. The <hostname> value is different for each sender. This sieve filter does not match any message: require ["fileinto","envelope","reject","vacation","imapflags","relational","co mparator-i;ascii-numeric","regex","notify"]; require ["body", "fileinto", "regex"]; # currentops reports if header :contains "Subject" ".* operations run" { fileinto "currentops"; stop; } However, a similar filter will match if, and only if, the string occurs at the beginning of the subject line. The various sieve help pages I've found suggest that pattern matching anywhere in the subject line should work, not just at the beginning. How to achieve this? TIA dn

[Dovecot] Annoying "feature" in dovecot/pidgeonhole - include depth limitation
by Mihai Moldovan 11 Sep '11

11 Sep '11

Hi all, I'm using dovecot 2.0.14 build on Debian. The maintainers obviously patch the dovecot source so that it uses the pidgeonhole sieve system. Today I ran into a very annoying issue: I created several sieve scripts and interlinked via the include command, only to find dovecot spewing this error message at me: SWREG Newsletter: line 14: error: cannot nest includes deeper than 10 levels. As far as I could see this limitation is hardcoded to a depth of 10 and can only be changed at compile time. Why is it in place? I understand that you CAN create loops via the include command and limiting the inclusion depth is a way to circumvent loops - but ten is a very low value and the fact that you can't change it via a config file or sorta is even worse. My "fix" so far has been ignoring this, i.e. not returning false. I'm pretty sure that's not the best way to do it but it seems to be working so far. I'd really like to hear your opinion on this issue. Best regards, Mihai **

[Dovecot] Sieve, before script - Can it include "personal" scripts?
by Steve Fatula 11 Sep '11

11 Sep '11

Using sieve_before, can the script it references include a file from the personal space? I want to set some parameters (by user using the variables extension) there to control what the before script does, so, every user would have the file in their personal include space. If not, is there another way? Can the sieve_before and sieve_global_path be set from userdb extra fields?

Hi list, currently I use dovecot v1.2.15 with maildir++ mailboxes. (Debian Squeeze) I want to set up a different server with dovecot v2, also maildir++ mailboxes. (also Debian Squeeze) What is the best way to copy the existing mailboxes from the older machine running dovecot v1.2.15 to the new naked machine? Greetz, Tobias

[Dovecot] debug user's message retrieval
by Костырев Александр Алекс еевич 10 Sep '11

10 Sep '11

Hi there! Is there any method to log user's activity with pop3 service? I'll try to explain situation: In maillog I saw that my dovecot lmtp saved four letters in user's mailbox. After a while I got a call from that user saying that he received nothing. Is there any method to log that that user RETR every single letter, maybe with full names of letter's id or something like that?

What webmail is this? It's Horde webmail. Webmail does pop. Yahoo and Gmail do it too. When I first set up the server, it did it on first login - obviously because the server had changed but it's doing it once a week now (and in fact, it did it twice today). It's not fatal, no one will die. It is a PITA though. Simon

[Dovecot] Mails repopping
by Simon Brereton 09 Sep '11

09 Sep '11

HI I don't know if this is a dovecot issue or a client one. But as Dovecot is the most recent change, I'll start here. I have a server that's been running Courier for about 6 years and in all that time I think I've only ever had 1 issues where an entire mail box was repopped by a webmail client. However, since moving to a new server and dovecot 4 weeks ago, I've now had the webmail client repop this account 4 times (there are about 230 mails in the account). Is there a setting I need to tighten to prevent/remedy this? I have no idea if it's happening on other accounts, but this is one that I see. The format is maildir. There has been no changes to the webmail client. Thanks. Simon

[Dovecot] copy and empty userA folder1, append to /var/mail/userB
by mathog 08 Sep '11

08 Sep '11

Dovecot 2.0.13 on a 64 bit linux. We have an archiver account on one machine. Most mailing lists that handles go directly to it and everything is fine. However, there is one campus list that will only send to real people. So for that one I subscribed. When one of these messages comes in, which is 1-2x per week, I copy it to an export folder and then manually run a script which does: cat ~me/mail/export >>/var/mail/archiver echo "" > ~me/mail/export That worked fine on our last system, but dovecot doesn't like it. It leaves the imap indices for the export mailbox in an inconsistent state, so that roundcube (through dovecot) refuses to drop messages into it. The error message roundcube emits is: ServerError: Mailbox isn't a valid mbox file. Presumably the second half is from dovecot. I need a supported way to go about this, so that the next time one comes in I can copy to that folder again. The export mailbox is always completely emptied. It would suffice if there was some way to force dovecot to create "empty"" .imap/export: dovecot.index.cache dovecot.index.log files. Note this isn't a problem for the archiver itself, since it doesn't have any imap indexed files. Suggestions? Thank you, David Mathog mathog(a)caltech.edu Manager, Sequence Analysis Facility, Biology Division, Caltech

JF, thank you for the reply. I'm just curious how to big players fix this problem, which seems impact systems with shared storage. Have a nice day.

[Dovecot] limit number of simultaneous lmtp deliveries ?
by Jan-Frode Myklebust 08 Sep '11

08 Sep '11

We have quite a few frontend mail gateways that deliver incoming email trough our dovecot director (lmtp proxy) to the backend lmtp servers, and are seeing this logged on the frontend mail gateways: Sep 5 10:51:56 mailgw1 postfix/lmtp[23443]: 0E2F41C01A: to=<me(a)example.com>, relay=loadbalancers.example.com[192.168.42.15]:24, delay=61, delays=0.02/0.3/31/30, dsn=4.4.0, status=deferred (host loadbalancers.example.com[192.168.42.15] said: 451 4.4.0 Remote server not answering (DATA output timeout) (in reply to end of DATA command)) It's a bit unclear to me if this leads to duplicate deliveries, or just delayed deliveries, but -- is there any way to limit the number of simultanous deliveries on either the dovecot director or the backend lmtp-servers ? Will "process_limit=10" work for "service lmtp"? -jf
