So far I have managed to download emails from Inbox and Sent folder. All the downloaded emails go to single folder 'new' from 'Maildir' directory. Please tell me if there is a way (configuration) to download emails in respective folders. "getmail" appears to support delivery to an arbitrary Maildir folder. See "getmail" documentation. You might want to read up about Maildir to see how it works. In particular you need to know that mail is delivered to a directory "new" (the delivery process involves the directory "tmp", but the message isn't considered delivered until it reaches the directory "new"), but gets moved to a folder "cur" when the Maildir is looked at. So mail could be in either directory "new" or "cur". (The design of Maildir attempts to address various problems, and only partially succeeds, and in other cases makes things worse than they would have been otherwise. But despite its flaws, it still has some strengths, such as reliability, (relative) simplicity, wide support, and the ease by which a message store can be queried/interrogated.) > Also, is there any need for Dovecot now? As I see it, I have managed to download emails from remote servers in maildir format using getmail. How and why would Dovecot fit in? Will Dovecot (via deliver and sieve) assist in segregated email storage (i.e. INBOX in 'new', DRAFTS in '.draft/new' etc). It might be handy to have Dovecot installed as it would mean you could "see into" the mail folders using an IMAP client such as Thunderbird. This will probably make it easier to get a handle on which messages are in which folders than trying to look in the Maildir directories directly. IMAP has a special folder called "INBOX" which appears as the Inbox in most IMAP clients. Under Maildir, in the default location, INBOX can be found at ~/Maildir/{new,cur,tmp} Other folders are mapped into directories, for example the mail folder "Sent" will appear at ~/Maildir/.Sent/{new,cur,tmp} Nested mail folders are flattened into a single directory level in the filesystem, with the folder levels separated by dots, so the mail folder "Projects/PJ1" will appear at ~/Maildir/.Projects.PJ1/{new,cur,tmp} (The above is the default way for Maildir to work. However, Dovecot can be configured to map IMAP folders into Maildir directories in other ways.) Bill

[Dovecot] Problem accessing Dovecot mailing lists via IMAP
by William Blunn 30 Jun '11

30 Jun '11

I recently tried to look at the Dovecot mailing lists through an already-configured IMAP profile, which had worked fine in the past. But it failed saying that the authentication method was not supported. http://www.dovecot.org/mailinglists.html says: "You can get access to the IMAP archives by using *dovecot.org* as the hostname, *anonymous* as the username and an empty password. It's also possible to use ANONYMOUS authentication mechanism if your client supports it (few do)." I noticed that my e-mail client was configured to use the server "imap.dovecot.org", so I changed it to "dovecot.org". But it still complains that the authentication method is not supported. I am using Thunderbird 3.1 over Windows 7 64-bit. Thunderbird was configured for "Password, Transmitted insecurely" (and this option was not working). I have tried the other authentication options available in Thunderbird. "Encrypted password": Does not work; same problem "Kerberos / GSSAPI": Does not work; same problem "NTLM": Does not work; same problem Any ideas? Bill

[Dovecot] what to expect from changing index location
by Davide Vaghetti 30 Jun '11

30 Jun '11

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello everybody, I have one thousand virtual users with mdbox mailbox format and 10 GByte quota. I have noticed some performance problem related to I/O (the mailbox disk is a 6TB raid1+0 on ISCSI), so I want to put the index files on a different disk. My actual mail_location is: mail_location = mdbox:/var/vmail/%-1.1u/%u/mdbox and I want to switch to mail_location = mdbox:/var/vmail/%-1.1u/%u/mdbox:INDEX=/var/indexes/%-1.1u/%u/ But I cannot figure out a pair of things: - - do the switch trigger the rebuilding of the index files? - - can I get rid of all the old index files? - - how much the index files (no fts squat) can grow? thanks in advance bye davide - -- Dott.

[Dovecot] Mbox corruption - Inbox beginning with 'FFrom'

I have two accounts where the inboxes sometimes get corrupted. In that case they begin with "FFrom". I saw similar reports in July/August last year.

[Dovecot] Migrating shared folders from courier-imap to dovecot
by Tom Clark 30 Jun '11

30 Jun '11

Hi, I'm hoping you'll be able to help. I'm working on a project to migrate our users from a courier-imap (4.3.0) based mail server to a dovecot (2.0.8) mail server. I have got all the users migrated and working. However, I can't see how to migrate the shared folders from courier-imap. I have tried to find extra information all the migration information seems to centre around a user mailbox rather than shared mailboxes. Is it simply a case of setting up the shared folders on dovecot, then copying the messages in, finally running the dovecot migration script across them? Any advice would be greatly appreciated. Thanks, Tom

[Dovecot] Denying user won't work as expected

Hello I tried to use the "deny user" feature but it does not work as expected ... ( dovecot 2.0.12 ) we use LDAP as authentication source I modified the 10-auth.conf file as the following # <doc/wiki/UserDatabase.txt> !include auth-deny.conf.ext #!include auth-master.conf.ext #!include auth-system.conf.ext #!include auth-sql.conf.ext !include auth-ldap.conf.ext #!include auth-passwdfile.conf.ext #!include auth-checkpassword.conf.ext #!include auth-vpopmail.conf.ext #!include auth-static.conf.ext I modified the auth-deny.conf.ext file as the following passdb { driver = ldap deny = yes # File contains a list of usernames, one per line args = /usr/local/etc/dovecot/deny-users } I have tested writting one user (me) in the /usr/local/etc/dovecot/deny-users and the result is the login is denied for ALL users ... If I do not uncomment the !include auth-deny.conf.ext line in 10-auth.conf file everything works well I really need this feature Thanks for any help

Re: [Dovecot] Question about "Storage keeps breaking" in logs

This dovecot box (RHEL 5.6 x64, dovecot 2.0.13, ext4) is a VM over vmware vsphere. The remote SAN disks are presented via iSCSI to the ESX hosts, and the ESX host show them as "local storage" /dev/sdX We have several VM sharing that datastore, no I/O contention detected. I will try with imaptest but this a production enviroment, I will take a couple of weeks to get a "mainteneance window" for this. Any other idea about this? Maybe this problem is load-related?

[Dovecot] permissions for dbox attachment directory
by imap＠tnde.org 30 Jun '11

30 Jun '11

I am running dovecot 2.0.13 on CentOS5, set up with only local system users, and single instance store set up in a single directory. e.g. mail_attachment_dir = /var/mail/attachments I get errors when importing mail to IMAP because the attachment directories are owned by the respective mail account user(s) and so cannot be accessed or written to by other users. Are there some user id setting I need to change, or do I have to run dovecot with virtual users under a single system account? Thanks!

Is vmail or dovecot user more appropriate for raw logging? >From wiki I got the impression that user must be same as the effective UID of logged in user, which in my setup is vmail(121).

Maybe you got NAT forwarding going on where a firewall or other network appliance (like a load balancer) is translating ip1/143 -> ip2/143? Or you're not on the host you think you're on. You can check the dovecot logs to verify that in fact your client is connecting. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Virtual Servers
by Daniel L. Miller 29 Jun '11

29 Jun '11

Maybe a little off-topic - but I hope not too much. Looking for some insight on setting up Dovecot under a virtual server. In particular, I use VirtualBox - and at the moment, Ubuntu Linux. Initial questions on configuration: Caching. It seems to me - and I'm probably wrong - that running a Linux in a VM on a Linux host, there would be a duplication of caching. That is, the host server has a file cache - and the VM, which is otherwise a standard Linux installation, is also going to try to cache its files. This strikes me as a duplication of effort and waste of RAM. Is this something I should devote any time to thinking about and trying to minimize? If so, how? Mail storage. My current mail store is a RAID-10, using the mdbox format. I wish to continue storing the mail on "raw" disks - not place the mail inside a virtual disk. Accordingly, the VM needs to reach the mail outside the VM environment - which according to conventional wisdom means NFS. My initial testing shows NFS results in a dramatically reduced performance for Dovecot. Given that this NFS access is going to be exclusively for Dovecot, and I'm only running a single server, are there any NFS or Dovecot tweaks I should implement? Is there an alternative connectivity for the VirtualBox environment I should explore? -- Daniel

It is an MRA and we shouldn't be required to install it on remote servers, right? What should I do to make dovecot work for remote servers?

[Dovecot] LDAP timeout
by Bernhard Schmidt 29 Jun '11

29 Jun '11

Hi, we recently hit an issue where one (of the three configured) LDAP servers dropped an index on an attribute due to a misconfiguration, which caused all/most queries for passdb to take a very long time (several 10s of seconds). The other servers would have been fine, but it seems like Dovecot does either not set a timelimit on the query or uses a very high one. I could not find any place to control that either. Is there any knob to tune the LDAP timeout? Bernhard

[Dovecot] Dovecot 1.2.16 -> Dovecot 2.0.13 Performance?
by Jorgen Lundman 29 Jun '11

29 Jun '11

Hello list, Currently running dovecot-1.2.16 as pop, imap, and deliver (with sieve). All on Solaris 10u9, on NFSv4 backends. All is working great. But occasionally, the system gets rather loaded, not entirely sure what part yet, but as part of researching that; If we were to start the upgrade path to dovecot 2.0.13, are there any known areas of performance increase which should encourage us to do this? Since we have a stable system, there is hesitation in changing any part of it :) Each NFS server hosts about 92,381 mailboxes, LDAP as authentication and ZFS user quotas. What sort of numbers do others manage generally?

[Dovecot] Sendmail + dovecot-lda + LDAP
by Василий Яковлев 28 Jun '11

28 Jun '11

Hi, I experince some problems with setting up Sendmail with the LDAP database for virtual mail accounts. Why i'm not writing to the LDAP mailing list? I believe, that the reason of my problem is in configuring dovecot-deliver. What i have: - FreeBSD 8.2-RELEASE - sendmail (Version 8.14.4 with LDAP support installed from ports) - Dovecot LDA + dovecot (as pop3/imap) - 1.2.16 - Cyrus Sasl (authdaemon for authentification) 1. Following http://wiki.dovecot.org/LDA/Sendmail i've set up deliver as LDA. Everything worked fine. 2. Following http://wiki.dovecot.org/HowTo/DovecotOpenLdap i've set up Dovecot to work with tha ldap. Now i can authorize through the client or web interface and get to my maildir. 3. Now, i want my sendmail to accept mail for the account in LDAP database. sendmail.mc: ++++++++++++++++++++++ FEATURE(`local_procmail', `/usr/local/libexec/dovecot/deliver',`/usr/local/libexec/dovecot/deliver -d $u') MODIFY_MAILER_FLAGS(`LOCAL', `-f') ...................................... define(`confLDAP_DEFAULT_SPEC', `-h "localhost" -b "dc=mydomain,dc=ru" -d "cn=dovecot,ou=accounts,dc=mydomain,dc=ru" -MLDAP_AUTH_SIMPLE -P /etc/mail/ldap_pass')dnl LDAPROUTE_DOMAIN(`mydomain.ru')dnl FEATURE(`ldap_routing', `null -T<TMPF>', `ldap -1 -T<TMPF> -v mail -k (&(objectclass=posixaccount)(mail=%0))', `passthru')dnl ......................................

User unknown ++++++++++++++++++++++ It's the problem of the local delivery, i believe. Why? Because after sendmail getting an email it passes it to the LDA, which must check the LDAP (not the passwd!) database for the user, to which this email is send to. Are there some possibilities to solve this problem? I appreciate any help... ----------------------- Best regards, Vasily Yakovlev ----------------------------------------------------------------------

[Dovecot] hide sieve folder from imap clients
by Christopher Stolzenberg 28 Jun '11

Hello, What is the best way to hide sieve folders from IMAP clients? old config mail_home = /var/vmail/%d/%n plugin { sieve_dir = /var/vmail/%d/%n/.sieve/ sieve = /var/vmail/%d/%n/.dovecot.sieve } new config (hide sieve folder) mail_home = /var/vmail/%d/%n maildir_stat_dirs = yes plugin { sieve_dir = /var/vmail/%d/%n/sieve/ sieve = /var/vmail/%d/%n/.dovecot.sieve } Is there a better way without maildir_stat_dirs = yes ? -- Christopher

[Dovecot] ACLs: Group ACL adds empty ACL for user of same name, why?
by Jim Hague 28 Jun '11

28 Jun '11

I'm playing around with ACLs, Groups and SOGo on Debian Stable, Dovecot 1.2.15. If I set an ACL for a group 'developers': 6 setacl "INBOX.Trash" "$developers" "lrsw" 6 OK Setacl complete. The dovecot-acl file for INBOX.Trash then contains a group setting for the group, and a user setting for a user of the same name, giving it no permissions. group=developers lrws user=developers and a subsequent GETACL reports the user: 5 getacl "INBOX.Trash" * ACL "INBOX.Trash" "$developers" lrws "developers" "" "jim" lrwstipekxacd 5 OK Getacl completed. Currently SOGo does not deal well with the unexpected non-existant user. So I'm curious - why's it there? -- Jim Hague - jim.hague(a)acm.org Never trust a computer you can't lift.

[Dovecot] Panic: doveadm quota get -A
by Urban Loesch 28 Jun '11

28 Jun '11

Hi, I'm new to the list and I'm using dovecot since 2 months. Still in progress to migrating from Stalker (Communigate Pro) to Dovecot. Today I upgraded from Dovecot 2.0.13-0~auto+27 (used form the Mirror xi.rename-it.nl - stable-auto) to 2:2.0.13-0~auto+48. List of installed packages: ii dovecot-common 2:2.0.13-0~auto+48 secure mail server that supports mbox, maildir, dbox and mdbox mailboxes ii dovecot-imapd 2:2.0.13-0~auto+48 secure IMAP server that supports mbox, maildir, dbox and mdbox mailboxes ii dovecot-lmtpd 2:2.0.13-0~auto+48 secure LMTP server for Dovecot ii dovecot-managesieved 2:2.0.13-0~auto+48 secure ManageSieve server for Dovecot ii dovecot-mysql 2:2.0.13-0~auto+48 MySQL support for Dovecot ii dovecot-pop3d 2:2.0.13-0~auto+48 secure POP3 server that supports mbox, maildir, dbox and mdbox mailboxes ii dovecot-sieve 2:2.0.13-0~auto+48 sieve filters support for Dovecot It seems all is working fine, except "doveadm quota get -A". It gives me the following error: # doveadm quota get -A doveadm: Panic: file doveadm-print-table.c: line 58 (doveadm_calc_header_length): assertion failed: ((value_count % hdr_count) == 0) doveadm: Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x3fd0a) [0x7fb901d0fd0a] -> /usr/lib/dovecot/libdovecot.so.0(default_fatal_handler+0x32) [0x7fb901d0fdf2] -> /usr/lib/dovecot/libdovecot.so.0(i_error+0) [0x7fb901ce916f] -> doveadm() [0x416bed] -> doveadm(doveadm_print_flush+0x1f) [0x40f1cf] -> doveadm() [0x40a92d] -> doveadm(doveadm_mail_try_run+0x11c) [0x40acfc] -> doveadm(main+0x381) [0x410761] -> /lib/libc.so.6(__libc_start_main+0xfd) [0x7fb901581c4d] -> doveadm() [0x409e09] Aborted I also tried the versions 2.0.13-0~auto+45 - 47 from xi.rename-it.nl. Same thing. Have you any idea how i can fix this.

Thanks. Solaris still uses /usr/lib/sendmail which is a pain since /usr/lib is rarely in shell search paths. Nothing a few symlinks can't fix. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Maildir parent directory permissions incorrect for new mailbox
by Dominic Marks 28 Jun '11

28 Jun '11

Hi, My issue is with the automatic creation of parent directories above new maildirs. It seems to be that they're being set with incorrect (or unhelpful) permissions, applying the permissions of the mailbox down the path towards the mailbox root, as opposed to taking the permissions of the mailbox root up towards the mailbox. Our mail is stored under the scheme: location = maildir:/var/dovecot/mail/%d/%n:INDEX=/var/dovecot/index/%d/%n Initially, /var/dovecot consists of acl, index and mail, all empty. The permissions on these are: >> ls -l total 6 drwxrwxr-x 2 hmgp hmgp 512 17 Jun 12:23 acl drwxrwxr-x 3 hmgp hmgp 512 17 Jun 15:56 index drwxrwxr-x 3 hmgp hmgp 512 17 Jun 15:56 mail If I perform a mail delivery to my mailbox, the mailbox parent directory is created with the following permissions: >> ls -l total 2 drwx------ 3 dm hmgp 512 17 Jun 15:56 insidetrading.co.uk Note that the user ID is my own and the mode restricts all other access. When I perform a second delivery to different mailbox under that domain, one mapped to a different UID, the delivery fails because that user cannot access the parent folder in order to create the new maildir. I've read on the Wiki that Dovecot copies permissions from the parent directory when adding new messages to a mailbox. That would suit my situation, but it doesn't happen here. Maybe there is there a reason why this is the case? I've had a look at the code and it it works in the opposite direction, starting from the full path (with its associated mode, uid & gid) and working by removing a section from the right-hand side each time. For me, at least, it would be better if it started from the bottom and worked upwards, inheriting the parent uid, gid and mode until the mailbox directory, where the existing behaviour would be retained, looking like: >> ls -dl insidetrading.co.uk/dm total 2 drwx------ 5 dm hmgp 512 17 Jun 15:56 dm I know I could hold all our mail under a single uid/gid or I could fix the mode manually, but I'd rather not do either. Am I missing some key configuration detail or should I work on a patch for this?
