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

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?

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?

Second question: Is there a way to include multiple imapc instances/ namespaces with e.g. different destinations servers? I don't see how because imapc_* parameters seem to be global (now), but it would be a very useful feature. Greetings, Lutz

[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. Tim. -- Tim Bishop http://www.bishnet.net/tim/ PGP Key: 0x5AE7D984

[Dovecot] setacl on complete mailbox
by Tobias Hachmer 12 Sep '11

12 Sep '11

Hi List, how can I grant a user full control on another mailbox (the complete mailbox with all folder and subfolders). With the setacl command I could do this but first I have to list all folders and then I have to do one setacl command for each folder. Is there a command to this in one line? Also for new created folders? Greetz, Tobias

[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 **
