[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'
by Uwe Klaus 30 Jun '11

30 Jun '11

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. So I applied the patch http://dovecot.org/pipermail/dovecot/attachments/20100720/e87b32ae/attachme… Yesterday a mbox corruption happened again. Here are the log lines.

[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

Hi, How do I get the LMTP-server to know which mailbox's are locally hosted and return SMTP code 450 if delivery is attempted to a non local user? I can see that a lookup in the userdb is done, but now matter what I return (1/111) from my checkpassword script I just get: 451 4.3.0 <lp(a)domain.tld> Internal error occurred. Refer to server log for more information. /Peter

[Dovecot] Denying user won't work as expected
by Frank Bonnet 30 Jun '11

30 Jun '11

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
by Maria Arrea 30 Jun '11

30 Jun '11

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!

[Dovecot] Rawlogging uid

Hi, this is my first post to the list after years of passive following every now and then. Dovecot: 2.0.13 (3d07ab746a67) prebuilt binaries from xi.rename-it.nl OS: i686 Debian 6.0 squeeze/sid I am about to run a setup where users are virtual and their mail is owned by vmail user. I bumped into minor client issue and needed to enable rawlogging according to http://wiki2.dovecot.org/Debugging/Rawlog This is what was printed to log at first try: Jun 29 21:46:25 (null)Fatal: This process must not be run as root I changed service postlogin to contain "user = vmail" and above error disapperead. I also tried "user = dovecot" which seem to work as well. 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). Also, maybe the (null)Fatal -message could be improved(?). # dovecot -n # 2.0.13 (3d07ab746a67): /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-1-686 i686 Debian squeeze/sid ext3 auth_debug = yes auth_verbose = yes debug_log_path = /var/log/dovecot/debug.log first_valid_gid = 123 first_valid_uid = 121 info_log_path = /var/log/dovecot/info.log last_valid_gid = 123 last_valid_uid = 121 lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes lmtp_save_to_detail_mailbox = yes log_path = /var/log/dovecot/dovecot.log mail_debug = yes mail_location = maildir:/home/vmail/%n/Maildir managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date namespace { inbox = yes location = prefix = separator = / type = private } passdb { driver = pam } plugin { sieve = /home/vmail/%n/dovecot.sieve sieve_dir = /home/vmail/%n/sieve sieve_extensions = +enotify +subaddress +vacation } protocols = " imap lmtp sieve" rejection_reason = Your message to <%t> was rejected: %r rejection_subject = Mail delivery failed: returning message to sender service auth { unix_listener auth-userdb { group = vmail mode = 0660 } } service imap { executable = imap postlogin } service postlogin { executable = script-login rawlog user = vmail } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = uid=121 gid=123 driver = passwd } userdb { args = uid=121 gid=123 allow_all_users=yes home=/home/vmail/%n driver = static } protocol lda { info_log_path = /var/log/dovecot/lda-info.log log_path = /var/log/dovecot/lda.log mail_plugins = sieve } -- Mikko

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] 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

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".

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?

[Dovecot] UIDL and message migration
by Hugo Monteiro 28 Jun '11

28 Jun '11

Hello, I'm in the process of migrating accounts between two dovecot servers. An old server running ancient 1.0.15 and a new server running 1.2.15. Account migration is going to be gradual and so i would like to use imapsync to move messages and subscriptions from one server to the other. The only problem so far is with POP users. After doing an account migration with imapsync, and although both servers share the same pop3_uidl_format = %08Xu%08Xv, the client downloads every message that was already on the server. Any pointers would be very much appreciated. Best Regards, Hugo Monteiro.

[Dovecot] problem with dovecot and sieve
by Javier 28 Jun '11

28 Jun '11

Hi We've been using dovecot with great success so far. We are trying to add sieve support for our users. We enabled managesieve and users can define rules from the webmail (roundcube) with sieverules plugin for roundcube. Everything goes ok, but here's a problem I couldn't figure yet. When I define a redirect rule, the mail is forwarded but a local copy is stored too. Weird thing is that the logs say redirecting failed but the mail gets forwarded. Let me show you some of this (personal data masked): # cat .dovecot.sieve ## Generated by Roundcube Webmail SieveRules Plugin ## # rule:[teste] if anyof (true) { redirect "xxxxx@xxxxxxxxx"; } And the log from the user's sieve log sieve: info: started log at Jun 15 18:05:49. error: msgid=<BANLkTik1OzJEreF0qW000OvFpkaR7nOhCQ(a)mail.gmail.com>: failed to redirect message to <xxxxxx@xxxxxxx> (refer to server log for more information). syslog: Jun 16 11:40:26 mailstore5 dovecot: lmtp(8458, xxxxxxx(a)xxxxxx.com) Error: /eMhMNoV+k0KIQAAmtbU9A: sieve: execution of script /var/maildir++/99/xxxxxx(a)xxxxxxxx/.dovecot.sieve failed, but implicit keep was successful (user logfile /var/maildir++/99/xxxxxx(a)xxxxx.com/.dovecot.sieve.log may reveal additional details) And gets redirected anyway Jun 16 11:40:26 mailstore5 postfix/smtp[13041]: CB4D1C79FE: to=<xxxx@xxxxxxx>, delay=0.12, delays=0.02/0/0.01/0.08, dsn=2.0.0, status=sent (250 2.0.0 Ok: queued as E24FAB0880) There's no explicit keep anywhere in the sieve rule, nor a global rule, so Im confused, the email should be forwarded only. The error message confuses me too, as it says failed but the mail gets through. dovecot -n # 2.0.9: /opt/mail/dovecot/etc/dovecot.conf # OS: Linux 2.6.36.2 x86_64 Debian 5.0.8 auth_mechanisms = plain login base_dir = /opt/mail/dovecot/var disable_plaintext_auth = no listen = * mail_location = maildir:~/Maildir mail_plugins = create_mbox quota managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include varia passdb { args = socket=/opt/mail/auth_server/var/socket timeout=10 driver = courier } plugin { quota = maildir:User quota quota_rule = Trash:ignore quota_rule2 = Spam:ignore sieve = ~/.dovecot.sieve } protocols = imap pop3 lmtp sieve service imap-login { inet_listener imap { port = 30143 ssl = no } } service lmtp { inet_listener lmtp { address = 0.0.0.0 port = 30024 } process_min_avail = 4 } service pop3-login { inet_listener pop3 { port = 30110 } } ssl = no ssl_parameters_regenerate = 0 userdb { args = socket=/opt/mail/auth_server/var/socket timeout=10 driver = courier } protocol pop3 { mail_plugins = create_mbox quota maildiraccess pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_reuse_xuidl = no pop3_save_uidl = no pop3_uidl_format = %f } protocol imap { mail_plugins = create_mbox quota imap_quota maildiraccess } protocol lmtp { mail_plugins = create_mbox quota sieve } protocol sieve { mail_debug = yes } Your help is appreciated.

[Dovecot] User doesn't have home dir set, disabling duplicate database
by Claudio Prono 28 Jun '11

28 Jun '11

[Dovecot] Thunderbird or Dovecot causing duplicates
by Tim 28 Jun '11

28 Jun '11

Hey everyone, back on the list after a few years away. I have a strange issue that is just annoying. Trying to work out if it's Dovecot or Thunderbird causing the problem. Basically, I read an email (so it gets marked as read) and then very quickly I mark is as unread, (i.e. I realised I want to leave that email for later) which causes a duplicate email to be created. Generally I believe both duplicates are then marked as unread, but I've not taken too much notice of that part yet, other than the new email (the duplicate) being marked as unread. This has also happened when deleting emails from a junk folder. It seems to be events happening quickly that ether Thunderbird or Dovecot don't keep up with, so think the state of the message hasn't changed, so recreate the message maybe? I'm not really sure, so was hoping someone else had experienced the issue or could shed some light on it. Thanks Tim The logs from when I managed to recreate this manually this morning as a test.

[Dovecot] %d empty string
by Ryan Dotson 28 Jun '11

28 Jun '11

I am trying to upgrade from dovecot 1.x to Dovecot 2.0.13 on Fedora. My problem is the mail_location setting seems to ignore the %d variable. My my location is as follows: mail_location = maildir:/var/spool/virtual_mail/%d/%u/Maildir However, when trying to log in the maillog says it can't find /var/spool/virtual_mail//*myusername*/Maildir/cur. As you can see it just uses an empty string for the %d variable. Can anyone help? Thanks, Ryan

[Dovecot] Multiple values found for 'user', using value

Hi since latest upgrade on my machine, i have lot of warnings in my log, and i found that it is due this change http://www.dovecot.org/list/dovecot-cvs/2011-February/018588.html Is there any option to disable these warnings ? Yes we have multiple UIDs so these warnings bothers me. Many thanks Regards Martin

[Dovecot] Default sendmail_path value
by Joseph Tam 28 Jun '11

28 Jun '11

It appears the documentation of this parameter is inconsistent with the documentation: > grep -nF /sendmail `gfind src -type f` src/lib-lda/lda-settings.c:41: .sendmail_path = "/usr/sbin/sendmail", src/config/all-settings.c:732: .sendmail_path = "/usr/sbin/sendmail", (and doc/example-config/conf.d/15-lda.conf is also consistent with this) but the documentations states http://wiki2.dovecot.org/LDA sendmail_path is used to send mails. Note that the default is /usr/lib/sendmail, which doesn't necessarily work the same as /usr/sbin/sendmail. I don't know which ought to be changed though. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Help regarding getting password policy response
by sarguru 28 Jun '11

28 Jun '11

Hello, I have enabled ldap password policy in my open ldap server and it locks out the account after several unsuccessful bind attempts. I am able to get the password policy response which says "Account locked" by specifying '-e ppolicy' option in my ldapsearch command. I am looking for a way to get similar response when I use dovecot so that I can specify my clients that their account is locked. I understand the security risks involved but mine is low security and high usability requirement. Please share the solution with me. -- Thanks, Sarguru

[Dovecot] Extra plugins vía extrafield in ldap
by Antonio Perez-Aranda 28 Jun '11

28 Jun '11

Hi all, I'm using dovecot 2.0.9 and I have a config like this: dovecot.conf: passdb { args = /etc/dovecot/conf.d/passwd-ldap.conf driver = ldap } mail_plugins = $mail_plugins quota plugin { autocreate = INBOX.SPAM autocreate2 = INBOX.NoSPAM autosubscribe = INBOX.SPAM autosubscribe2 = INBOX.NoSPAM quota = maildir } protocol imap { mail_plugins = $mail_plugins imap_quota autocreate } And in passwd-ldap.conf I have some like this to add extra plugins: user_attrs = homeDirectory=home,uid=user,mailQuota=quota_rule=*:bytes=%$,mailPlugins=mail_plugins With this. I can see that dovecot load all plugins from settings, but in the user session, I can get only the plugins that I have selected in mailPlugins field If i check some like this: mailPlugins=mail_plugins=$mail_plugins %$, The imap session user is aborted after login. How can I add extra plugins by ldap without put on ldap all user plugins? -- Antonio Pérez-Aranda Alcaide aperezaranda(a)yaco.es Yaco Sistemas S.L. http://www.yaco.es/ C/ Rioja 5, 41001 Sevilla Teléfono +34 954 50 00 57 Fax +34 954 50 09 29

[Dovecot] dovecot security with IPv6
by Kārlis Repsons 27 Jun '11

Hi Timo, hi all others! In fact, I've only read one person claiming that IPv6 support opens up "too many backdoors" [1], but anyway, as I intend to run just particular services, please give me your opinion if it's insecure to have a dovecot server, which is accessed through a public IPv6 address... (or note just shortly what else could give a firm ground to such claims...) [1] http://forums.gentoo.org/viewtopic-t-882557.html

[Dovecot] Sendmail + dovecot-lda + LDAP
by Василий Яковлев 27 Jun '11

27 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 - sendmail (Version 8.14.4 with LDAP support installed from ports) - Dovecot LDA + dovecot (as pop3/imap) - 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 ...................................... MAILER(procmail) ++++++++++++++++++++++ After re-making the sendmail: ++++++++++++++++++++++ [root@test2 /etc/mail]# sendmail -bv -d60.1 test_user(a)mydomain.ru map_lookup(dequote, test) => NOT FOUND (0) map_lookup(host, mydomain.ru) => mydomain.ru.

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.

[Dovecot] dovecot global sieve script problem
by Dhaval Patel 27 Jun '11

27 Jun '11

I cutover to a new server which uses Postfix & Dovecot to handle emails as opposed to Postfix & Courier in the old server. Below is the contents of my global sieve script and dovecot config info. The dovecot-deliver.log does show that the email is being delivered to INBOX.spam but it ends up in the INBOX instead. If I put the exact same rule in the user script, the emails are delivered into the INBOX.spam folder. Currently as a work around, I created user rules for all users and add this. For most users, it is the only rule. So my question is, why does it not work with the global script? Any help would be appreciated.

[Dovecot] Please help with Quota dict mysql configuration
by Denis Iskandarov 24 Jun '11

24 Jun '11

Hello So what i have: centos 5.6 postfix 2.3.3 dovecot 2.0.13 postfixadmin 2.3.3 roundcube 0.5.3 All general things are working right now i can send receive email with ssl connections etc... Now i'm trying to configure additional options like quota and some other plugins like sieve, trash, expire and deleted-to-trash. Configuration of quota is on first place. I have read wiki regarding quota config , dict config but can't make things running. Hope there are normal sample configs you can share with me. I'm total noob in sql, so it's very difficult for me to arrange stuff in a way i need. My configs: dict { quota = mysql:/etc/dovecot/conf.d/sql/dovecot-dict-sql.conf # expire = sqlite:/etc/dovecot/dovecot-dict-sql.conf } dovecot-dict-sql.conf sample i took from postfixadmin docs provided with package, also changed table to quota2 as suggested for dovecot 2: driver = mysql connect = host=localhost dbname=postfix user=postfix password=postfixadmin default_pass_scheme = MD5-CRYPT table = quota2 select_field = current where_field = path username_field = username my sql.conf i took it from tutorial on your wiki : LDA postfix postfixadmin: driver = mysql connect = host=localhost dbname=postfix user=postfix password=postfixadmin user_query = SELECT concat('/home/vmail/', maildir) as home, concat('maildir:/home/vmail/', maildir) as mail, 1001 AS uid, 12 AS gid, concat('maildir:storage=', quota) AS quota FROM mailbox WHERE username = '%u' AND active = '1' #user_query = SELECT maildir, 1001 AS uid, 1001 AS gid, CONCAT('dict:storage=',floor(quota/1000),' proxy::quota') as quota FROM mailbox WHERE username = '%u' AND active='1' password_query = SELECT username as user, password, concat('/home/vmail/', maildir) as userdb_home, concat('maildir:/home/vmail/', maildir) as userdb_mail, 1001 as userdb_uid, 12 as userdb_gid FROM mailbox WHERE username = '%u' AND active = '1' The second user_query string i took from postfixadmin docs. But i dont know how to aply it. If it is better to use with mysql/postfixadmin and after this all i dont how to configure quota.conf (90-quota.conf): plugin { #quota = dirsize:User quota #quota = maildir:User quota #quota = dict:User quota::proxy::quota #quota = fs:User quota } # Multiple quota roots are also possible, for example this gives each user # their own 100MB quota and one shared 1GB quota within the domain: plugin { #quota = dict:user::proxy::quota #quota2 = dict:domain:%d:proxy::quota_domain #quota_rule = *:storage=102400 #quota2_rule = *:storage=1048576 } Please help me with configuration. I really stuck with this thing. And yes i've tried to find solutions on mailing list, but no luck. I want per domain/user quota in mysql. Also space usage to be shown in roundcube. Hope to get proper help ... And sorry... Thanks in advance.

[Dovecot] Error with Dovecot LDA when using recipient address misses user part
by Nikolaos Milas 23 Jun '11

23 Jun '11

Hi, We are using Postfix 2.8.3 with Dovecot 2.0.13 on CentOS 5.6. The problem we have is that sometimes, due to mail sender's error when composing a message, the sender attempts to send an email to "@noa.gr" (without specifying the user part of the address). This results in a Postfix error due to Dovecot LDA use: Jun 22 21:05:31 vmail postfix/pipe[31862]: CC89FC4D210: to=<@noa.gr>, relay=dovecot, delay=0.41, delays=0.24/0.013/0/0.15, dsn=5.3.0, status=bounced (command line usage error. Command output: /usr/libexec/dovecot/dovecot-lda: option requires an argument -- d Usage: dovecot-lda [-c <config file>] [-a <address>] [-d <username>] [-p <path>] [-f <envelope sender>] [-m <mailbox>] [-e] [-k] ) Postfix master.cf is configured as: dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/libexec/dovecot/dovecot-lda -f ${sender} -d ${user} Obviously this happens because in this case there is no ${user} data. My question is: Can we somehow configure things in a way so as to avoid this error when someone sends an email with blank sender data? Can Dovecot provide some meaningful message to postfix (like "No user specified") instead of failing with a "command line usage error"? Thanks, Nick

Hi I'am doing some tests with nginx proxy -> dovecot using imaptest: imaptest user=user host=host pass=pass msgs=50 clients=100 Logi List Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo 100% 50% 50% 100% 100% 100% 50% 100% 100% 100% 100% 30% 5% 41 19 10 36 24 39 9 13 11 8 12 100/100 10 12 11 17 24 31 3 24 38 46 94 100/100 24 13 13 24 26 33 10 22 25 25 52 100/100 27 13 12 25 23 26 9 19 23 24 48 100/100 25 14 13 27 27 40 7 19 27 28 56 100/100 36 12 16 33 28 39 7 23 20 24 44 99/100 17 12 8 19 18 27 5 18 27 28 60 99/100 27 12 11 25 22 27 6 18 22 25 50 100/100 24 13 12 27 25 34 1 21 24 28 52 100/100 26 5 11 25 20 30 10 14 18 20 42 100/100 from what I have seen the results look pretty low , but what I can't really find is the meaning of numbers under each imap command. Can anyone explain what this numbers represent. Thank you Alex

[Dovecot] Mysql access denied
by list＠airstreamcomm.net 23 Jun '11

23 Jun '11

Currently using dovecot 2.0.12 and mysql server 4.0.20 (I know, it's really old) and having issues getting Dovecot to authenticate to the mysql server. We have confirmed that the credentials are correct and the host machine can access the database, however we are getting the following error: Jun 23 08:12:50 hostname dovecot: auth: Error: mysql(databaseserver.com): Connect failed to database (database): Access denied for user: 'sqladmin(a)ip.of.host.machine' (Using password: YES) - waiting for 1 seconds before retry We are assuming this has something to do with the password hashing algorithm in older versions of mysql, but we are hoping to confirm this theory and find a solution. Thanks.

[Dovecot] Custom Trash (etc) location
by fusionstream 23 Jun '11

23 Jun '11

Hi there. I have dovecot 1.2.17 installed on me system. I'd like to create a gmail-esque imap tree where all imap folders except for the inbox are in a subdirectory(?). More importantly, I'd like the email client (specifically thunderbird) to be able to recognise the folders and thusly give it a special trash/junk/etc icon which I presume also makes trash and junk go to, well the truash and junk folders automagically. Based on searching the web, I believe that namespaces are the solution. I believed that I had set it up to be 1) Inbox 2) IMAP - Drafts - Junk - Trash - etc However, when trying to use namespaces, I get IMAP.Drafts, IMAP.Junk and all the other folders also appearing in INBOX, in addition to another top-level IMAP.*. What am I doing wrong? If I understand the solutions posted on the web correctly, solving this (resulting in only one of each type of folder) should make thunderbird automagically recognise these "special folders". This is my configuration: # 1.2.17: /etc/dovecot.conf # OS: Linux 2.6.18-238.12.1.el5 i686 CentOS release 5.6 (Final) ext3 ssl_ca_file: /etc/postfix/ssl/cacert.pem ssl_cert_file: /etc/postfix/ssl/smtpd.crt ssl_key_file: /etc/postfix/ssl/smtpd.key login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login first_valid_uid: *[removed]* last_valid_uid: *[removed]* first_valid_gid: *[removed]* last_valid_gid: *[removed]* mail_location: maildir:/var/spool/mail/virtual/%d/%n mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugins(default): autocreate mail_plugins(imap): autocreate mail_plugins(pop3): mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 imap_client_workarounds(default): outlook-idle delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail imap_client_workarounds(pop3): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh namespace: type: private separator: . prefix: INBOX. inbox: yes list: yes subscriptions: yes namespace: type: private separator: . prefix: IMAP. list: yes subscriptions: yes lda: postmaster_address: postmaster(a)example.com auth default: mechanisms: plain login user: dovecot-auth passdb: driver: sql args: /etc/dovecot/mysql.conf userdb: driver: sql args: /etc/dovecot/mysql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 509 user: postfix group: postfix plugin: autocreate: IMAP.Trash autocreate2: IMAP.Spam autocreate3: IMAP.Sent Mail autocreate4: IMAP.Drafts autosubscribe: IMAP.Trash autosubscribe2: IMAP.Spam autosubscribe3: IMAP.Sent Mail autosubscribe4: IMAP.Drafts Any help appreciated.

[Dovecot] SQL config error

Currently using 2.0.12, configured the auth-sql.conf to look like this for password lookups (doing smtp auth with postfix, so I am not actually running pop or imap, just auth): passdb { driver = sql connect = host=server.net dbname=passwd user=sqluser password='password' default_pass_scheme = CRYPT password_query = SELECT CONCAT(username,'@domain.net') as user, pw as password FROM passwd WHERE username = '%n' # Path for SQL configuration file, see example-config/dovecot-sql.conf.ext args = /etc/dovecot/dovecot-sql.conf.ext } Starting Dovecot I am getting the following error: # 2.0.12: /etc/dovecot/dovecot.conf doveconf: Fatal: Error in configuration file /etc/dovecot/conf.d/auth-sql.conf.ext line 8: Unknown setting: connect This is my first time configuring SQL for Dovecot so I am not sure how "connect" is recognized as an unknown setting?

[Dovecot] Change passwd backend over cron: what happens if changes while reading?
by Denny Schierz 22 Jun '11

22 Jun '11

hi, I want to use two backends für DoveCot. One generated file from the LDAP tree, and the real LDAP. The first backend is generated from a cronjob thats reads the whole ldap server and converts them into a DoveCot passwd file. I red in the Wiki, if the user password isn't correct, than DoveCot asks the second backend (LDAP). Is this correct? Because, the the user can change his password, but Cron generates only every hour the file. So the password in the passwd-file isn't correct, until Cron runs again. The second, what happens, if Dovecot reads the file and in the same moment, Cron generate the new file? Does he change to the second backend? Or do I (the user) get an error? cu denny

[Dovecot] Performance settings for 500-1000User/per day
by Denny Schierz 22 Jun '11

22 Jun '11

hi, we have 2.0.13 running and most works well, but today we had some minor problems: The IMAP login process takes sometimes to much time. Over webmail (Roundcube 0.5.0.3) login wasn't sometimes possible, the normal clients hasn't any problems, until they login. We had only ~ 20-30 active accounts, but 50-60 sessions. The most are Apple products (Ip*/Mac/. ..)because they have 4 sessions or more open. Also we had ~212 processes with: dovenull 2065 4364 0 14:50:32 ? 0:00 dovecot/imap-login vmail 2403 4364 0 14:58:31 ? 0:00 dovecot/imap So, maybe, it's a miss configuration .... Any suggestions are welcome for 500-1000User per day.

[Dovecot] high number of processes
by Egbert Jan van den Bussche 22 Jun '11

22 Jun '11

Hi, Sometimes a script kiddie tries to guess passwords on our mailserver (Ubuntu 10.04.2 LTS, postfix, dovecot 1.2.9, scanners, the standard stuff). That leads to a nagios message about the high number of processes. The number goes above 500. Nagios threshold is set to 250, which is more than enough for normal operation of this server. When are these processes supposed to die again? They seem to stay at the high count quite long. Is there a way to limit the generation of extra login processes? Can I tune the login_process... params a bit? I have then all on default. dovecot - n below: root@mail-dev:/etc/dovecot# dovecot -n # 1.2.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-32-server x86_64 Ubuntu 10.04.2 LTS log_path: /var/log/dovecot/error.log info_log_path: /var/log/dovecot/info.log log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap pop3 imaps pop3s listen: *, [::] ssl_cert_file: /disk/site/etc/ssl/hobby.nl/hobby.nl.crt ssl_key_file: /disk/site/etc/ssl/hobby.nl/hobby.nl.key ssl_cipher_list: ALL:!LOW:!SSLv2:ALL:!aNULL:!ADH:!eNULL:!EXP:RC4+RSA:+HIGH:+MEDIUM disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login first_valid_uid: 200 mail_privileged_group: vmail mail_location: maildir:~/Maildir mmap_disable: yes dotlock_use_excl: no mail_nfs_storage: yes mail_nfs_index: yes mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/imap-wrapper.sh mail_executable(imap): /usr/lib/dovecot/imap-wrapper.sh mail_executable(pop3): /usr/lib/dovecot/pop3-wrapper.sh mail_plugins: convert autocreate mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 imap_client_workarounds(default): outlook-idle delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail imap_client_workarounds(pop3): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh lda: postmaster_address: postmaster deliver_log_format: msgid=%m: %$ rejection_subject: Rejected: %s rejection_reason: Your message to <%t> was automatically rejected:%n%r auth_socket_path: /var/run/dovecot/auth-master auth default: mechanisms: plain login realms: kader.hcc.nl hobby.nl default_realm: kader.hcc.nl cache_size: 1024 cache_ttl: 10 passdb: driver: pam args: failure_show_msg=yes cache_key=%u dovecot passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf socket: type: listen client: path: /var/spool/postfix/private/dovecot-auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail group: vmail plugin: convert_mail: mbox:/disk/mail/convert/%n autocreate: Trash autocreate2: Sent autocreate3: Drafts autocreate4: Spam autosubscribe: Trash autosubscribe2: Sent autosubscribe3: Drafts autosubscribe4: Spam login_process defaults: #login_user = dovecot #login_process_size = 64 #login_process_per_connection = yes #login_processes_count = 3 #login_max_processes_count = 128 #login_max_connections = 256 lsof -n output (part of long list): dovecot-a 12941 root 17u unix 0xffff88012a457300 0t0 13606994 /var/run/dovecot/login/default dovecot-a 12941 root 18u unix 0xffff8800272bd800 0t0 13565904 /var/run/dovecot/login/default dovecot-a 12941 root 19u unix 0xffff8800a68a9800 0t0 13610586 /var/run/dovecot/login/default TNX for any advise!

[Dovecot] LIST-EXTENDED support?
by fusionstream 22 Jun '11

22 Jun '11

Hi there. Can I check if LIST-EXTENDED refers to RFC 6154 (http://tools.ietf.org/html/rfc6154) rfc for special use mailboxes. I'd like to specify a designated folder as \Spam and etc. Googling "dovecot list-extended" and "dovecot special use" suggests that dovecot supports this feature (via patch logs and 1 bug report for Mozilla Thunderbird which suggests that dovecot supports this). However when trying to test this feature via thunderbird, it would seem to suggest that it is not currently possible. (Moving folders that Thunderbird has created forces thunderbird to recreate said folder in it's original location) # dovecot --version 1.2.17 Any help/pointers appreciated. Cheers.

[Dovecot] DoveCot LDA/Postfix deliver by address
by Zhou, Yan 21 Jun '11

21 Jun '11

Hi there, I am using DoveCot 1.0.7 and virtual users. We want to integrate with Postfix 2.3.3 to use DoveCot LDA to deliver messages to user mailbox. All users are stored in LDAP. DoveCot looks up user by LDAP access. Our user name is not necessarily part of the address. For instance, address "zhouy@xxxx" may be with user "yzhou", thus all messages to "zhouy@xxxx" should go to /home/vmail/yzhou/Maildir I do not see how LDA can support a two-step lookup: 1. Look up user from the given address, 2. Lookup user mail directory from the user in step 1. My understanding is that /etc/dove-ldap.conf is a one-step lookup, it only does user lookup (without password lookup). Any suggestions?

[Dovecot] DoveCot LDA/Postfix get address rather than user from messages
by Zhou, Yan 21 Jun '11

21 Jun '11

Hi there, We are using Postfix and DoveCot 1.0.7, using DoveCot LDA/Postfix to deliver messages to mailboxes via LDAP lookup. My Postfix 2.3.3 /etc/postfix/master.cf reads like this dovecot unix - n n - - pipe flags=Rhu user=hubdirect argv=/usr/libexec/dovecot/deliver -f ${sender} -d ${recipient} And my /etc/dovecot-ldap.conf reads like this: user_filter = (&(objectClass=DirectUser)(username=%n)) user_attrs = userreference=user,usermaildirectory=mail,userhomedirectory=home I find the above "%n" value in "user_filter" I am getting is always the address, not "user part in user@domain" as the documentation says. Did I miss anything? Thanks, Yan Confidentiality Notice: The information contained in this electronic transmission is confidential and may be legally privileged.

[Dovecot] Dovecot 1.1.20+NFS OS changed issue
by गौरव जोशी 21 Jun '11

21 Jun '11

Hi, I am facing a wierd issue on dovecot while migrating OS of the server. I have CentOS 5.2 32bit OS , Dovecot 1.1.20 with NFS on the server. When I am migrating it to CenOS 5.6 32bit with same Dovecot version. I compiled the same version i.e. 1.1.20 again. Now when I check the number of connection on this new server I can see only 8-10 connections for IMAP and 8-10 for POP3, where on old server I can still see the number of connections crosses 500+. I checked system level configuration which I found identical, limits set to same as old server, still no change in number of connections. I even tried the above exercise on CentOS 5.6 64bit version. again the result is same. I have tried all the changes/configurations I could think of.

[Dovecot] dovecot-metadata-8 released
by Dennis Schridde 20 Jun '11

20 Jun '11

Hello everyone! I just released dovecot-metadata-8, which is an implementation of RFC 5464 (IMAP METADATA), allowing to add comments/annotations/metadata to folders of an email account. The major feature is that it works with Akonadi, or more specifically the Kolab backend thereof, while being dovecot-2.0 compatible. The module consists of 3 plugins, two IMAP frontends and one backend: * "imap-annotatemore" is a partial implementation of draft-daboo-imap- annotatemore-08 (early predecessor to RFC 5464), based on work by Bernhard Herzog (Intevation GmbH). The sole intention is to support Kolab, not to strictly implement the draft. * "imap-metadata" is a complete implementation of RFC 5464. Kolab clients do not (yet) use these commands. * "metadata" is the common backend imap-metadata and metadata were entirely written from scratch, while imap- annotatemore is an adaption of the work by Bernhard Herzog to the new backend. You can download the code via Hg [1] or as exported tarball [2] from the Hg webinterface. Please note that the README is outdated, as are some other files. The build process is pretty much straightforward, just make sure you have the dovecot headers available on your system: ./autogen.sh ./configure --with-dovecot=/path/to/dovecot make make install Next you need to adjust your dovecot config. The following works for me: == dovecot.conf == dict { metadata = file:/var/lib/dovecot/shared-metadata } == 10-mail.conf == mail_plugins = ... metadata == 20-imap.conf == protocol imap { mail_plugins = $mail_plugins ... imap_metadata imap_annotatemore } == 90-plugin.conf == plugin { metadata_dict = proxy::metadata } To allow a Kolab client to find (e.g.) the addressbook folder, issue this IMAP command after login: SETMETADATA "path/to/folder" ("/shared/vendor/kolab/folder-type" "contact") If you find any bugs (crashes, incompatibilities with RFC 5464, etc), please write me a mail. Be advised that this code is still experimental and might crash your server! @Timo: Please have a look at the src/*-ext.[ch] files, they contain extensions to the dovecot libraries and might be useful for others, too. Kind regards, Dennis Schridde [1] http://hg.dovecot.org/dovecot-metadata-plugin [2] http://hg.dovecot.org/dovecot-metadata-plugin/archive/bdf2445e101f.tar.gz

[Dovecot] Gmail like virtual mailboxes
by Aleve Sicofante 19 Jun '11

19 Jun '11

I'm new to this list so let me introduce myself: I'm a computer literate user (I've done some C programming long ago and can run a Linux system and do some light admin), I've never installed a mail server before and I'm in the process of migrating my family and my small business from Gmail (Google Apps) to a virtual server mainly for privacy reasons. I'm in love with Gmail's label system and I just plain hate traditional folders. I use hierarchical labels (as if they were folders but with a message belonging to many at the same time) and that MUST be preserved in the migration. I've looked at Courier's IMAP keywords implementation and it looks good, but everyone on the internet is recommending Dovecot, so here I am. I've tried hard to find information about using unlimited hierarchical labels, virtual mailboxes or any other way of mimicing Gmail's functionality with Dovecot, but I'm lost. First of all: can it be done? If so, is there any introductory documentation? (I've only found very sparse information.) Is it available for any storage format (mbox, maildir, dbox)? Any help will be very appreciated. -- Aleve Sicofante

[Dovecot] Vacation -- reply to another address than envelope from
by Vegard Svanberg 19 Jun '11

19 Jun '11

Vacation (Sieve) replies to the envelope address. However, I have a customer which receive e-mails from a service which sends e-mails on behalf of a user (submitted through a web form). So an e-mail would be like (envelope from and from-header is webformfromwhatever(a)foobar.com) From: webformfromwhatever(a)foobar.com To: mycustomer(a)hisdomain.com Reply-To: usersrealmailaddress(a)example.com I need the reply to go to the reply-to address. Can I handle this with Sieve? -- Vegard Svanberg <vegard(a)svanberg.no> [*Takapa@IRC (EFnet)]

[Dovecot] Default Global ACL

Can I use the .DEFAULT files with global acls to access all mailboxes without explicitly sharing them first? Or must a share be created for every individual mailbox before they will appear in the shared namespace? -- Daniel

[Dovecot] ACL Groups
by Daniel L. Miller 17 Jun '11

17 Jun '11

From the wiki: ACL groups support works by returning a comma-separated acl_groups extra field <http://wiki2.dovecot.org/UserDatabase/ExtraFields> from userdb, which contains all the groups the user belongs to. User's UNIX groups have no effect on ACLs (you can "enable" them by using a special post-login script <http://wiki2.dovecot.org/PostLoginScripting>). I've read that over several times - I still don't understand that. Are "ACL Groups" defined and managed by Dovecot - and described somewhere else in the docs - or are they UNIX groups that previously had no affect on mail access but by being listed in the "acl_groups" field they now have relevance? -- Daniel

[Dovecot] ACL enabled Public folder dovecot
by kumar shantanu 17 Jun '11

17 Jun '11

Hi All, I am trying to do ACL enabled Public folder on dovecot version 1.1.20, but the ACL thing is not working, the public folder is visible and accessible to everyone. My dovecot config for public folder is like ######## namespace public { separator = / prefix = Public/ location = maildir:/var/mail/public subscriptions = no } plugin { acl = vfile } ######### and I have my dovecot-acl file in /var/mail/public/.test which reads ** user=test(a)mydomain.com lrw ** but every user can see the public folders and subscribe to it, which I don't want :( Can someone please suggest. Thanks in Advance, Shantanu

[Dovecot] Converting CLIENT_MAIL_DATA_MAX_INMEMORY_SIZE to a configurable?
by Attila Nagy 17 Jun '11

17 Jun '11

Hi, Currently Dovecot's LMTPd writes incoming emails to mail_temp_dir if it's bigger than 128k. But I would like to spare those unnecessary operations (creating a file, deleting it, writing into it, reading from it, checking whether there is free space and if not, rejecting (temporarily) the message). Memory is cheap, disk IO is not. :) And BTW, on a lot of systems, /tmp is a memory file system already, so there is absolute no need for this. I only fired two greps so far before writing this mail, in the hope that I can spare writing, testing and sending a patch, which will be either rejected, or rewritten. :) So, am I right that the following constant would be needed to be converted into a configurable setting and the task is done? static int client_input_add(struct client *client, const unsigned char *data, size_t size) { if (client->state.mail_data->used + size <= CLIENT_MAIL_DATA_MAX_INMEMORY_SIZE && client->state.mail_data_output == NULL) { buffer_append(client->state.mail_data, data, size); return 0; } else { return client_input_add_file(client, data, size); } } It could be defaulted to 128k, but the user could set it "unlimited" (0 or -1, depending on the author's mood, 0 and/or -1 being unlimited, or 0 being 0, meaning don't even store a bit -doesn't really make sense to me). LMTP is mostly protected from the outside world, so I don't see too much DoS potential here (absolutely not more than in the tmpfs case). Thanks,

Re: [Dovecot] ZFS Filesystem Quota under Solaris 10 and Sparc

The original zfs implementation didn't have user quotas. You could only add quotas to individual file systems as a whole. They apparently added it into the source base in 2009: http://blogs.oracle.com/chrisg/entry/user_and_group_quotas_for but I'm not sure when/if it made it to production. My sol10u8 * (10/09) has it in the man page, but I know some things in the man page isn't in s10 (like sharesmb), so, as they say, ymmv. The current doc for user quotas are here: http://download.oracle.com/docs/cd/E19253-01/819-5461/gazud/index.html If you don't want to use the filesystem quotas, you have to change your rules/configuration to match what dovecot has. See doc/wiki/Quota.Configuration.txt. Hope this helps. -r

[Dovecot] quota_rule beeing ignored and set to system soft! quota
by Leon Meßner 16 Jun '11

16 Jun '11

Hi, originating from the same Problem Edgar Fuß described here [1] about "Zero-sized Maildir files and index corruption on over-quota" i setup quota = fs:user quotas with a quota_rule set to 1.5G to prevent getting those zero sized mail files. What happens now is that when the user is over system soft quota (1G) mails stop beeing delivered. Jun 16 19:05:45 mail dovecot: deliver(elont1): msgid=<20110616185545.05ab0f56@x201t>: save failed to INBOX: Quota exceeded (mailbox for user is full) This is bad as users get notified per mail by a script about beeing over quota (this mail is now beeing deferred). If i don't set a quota_rule i still get 0byte files (quota is ignored). If i set a higher than system quota quota_rule it still uses the system soft quota. I have a seconary mailserver which already uses dovecot 2.x but i can't test the feature there as it's running inside a jail and thus has no access to quota. I would like to keep this machine on 1.2.16 for now. dovecot -n output is below. thanks, Leon [1] http://www.dovecot.org/list/dovecot/2010-October/053554.html 19:20_root@mail:/usr/local/etc# dovecot -n # 1.2.16: /usr/local/etc/dovecot.conf # OS: FreeBSD 7.3-RELEASE-p2 amd64 log_path: /var/log/dovecot.log protocols: imaps pop3s managesieve listen: mail.physik-pool.tu-berlin.de ssl_cert_file: /etc/private/mail.physik.tu-berlin.de.pem ssl_key_file: /etc/private/physik.tu-berlin.de_privatekey.pem login_dir: /var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login login_executable(managesieve): /usr/local/libexec/dovecot/managesieve-login login_processes_count: 6 login_max_processes_count: 512 verbose_proctitle: yes first_valid_uid: 200 mail_privileged_group: mail mail_location: maildir:~/maildir mmap_disable: yes mail_nfs_storage: yes mail_nfs_index: yes mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_executable(managesieve): /usr/local/libexec/dovecot/managesieve mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugins(managesieve): mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 mail_plugin_dir(managesieve): /usr/local/lib/dovecot/managesieve imap_client_workarounds(default): delay-newmail netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(pop3): imap_client_workarounds(managesieve): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh pop3_client_workarounds(managesieve): namespace: type: private separator: / inbox: yes list: yes subscriptions: yes namespace: type: private separator: / prefix: mail/ location: mbox:~/mail list: yes subscriptions: yes lda: postmaster_address: postmaster(a)physik.tu-berlin.de log_path: info_log_path: mail_plugins: sieve quota quota_full_tempfail: yes sendmail_path: /usr/sbin/sendmail auth default: mechanisms: gssapi plain login krb5_keytab: /etc/mail.krb5.keytab gssapi_hostname: mail.physik-pool.tu-berlin.de worker_max_count: 120 passdb: driver: pam args: session=yes failure_show_msg=yes max_requests=100 userdb: driver: passwd args: blocking=yes plugin: sieve: ~/.dovecot.sieve sieve_dir: ~/.sieve quota_rule: *:storage=15728640 quota: fs:user

[Dovecot] Removal of mailist duplicates?
by Peter Bell 16 Jun '11

16 Jun '11

I am using mpop to fetch mail from my service provider (who use dovecot). I use dovecot to hold all my mail on a local slackware server, with sieve filters, based on 'List-Id', directing mailist postings to their own folders. I use thunderbird to read my mail on an ubuntu desktop. When I receive a reply to a posting I make to a mailist (such as this one), replies I receive are usually sent to me with cc to the list. I would expect, then, to receive the message twice - once in my personal mailbox, and once to the mailist folder. However, this doesn't happen - I only see the posting in the mailist folder. Can anyone tell me at which stage in the process the other message is being supressed? -- ------------------------------------------------------------------- Peter Bell Mob: +63 (0) 9287 340 343 Tagum City, Philippines.

[Dovecot] limiting number of login attempts from same ip
by Jürgen Obermann 16 Jun '11

16 Jun '11

Hello, is it possible to limit the number of pop3 (or imap) login attempts from one IP with dovecot to stop attackers? We recently had an attack from one IP-address lasting 50 minutes that tried 50000 pop3-logins with guessed users and passwords. I know about Fail2Ban but really would prefer an easy to configure solution inside of dovecot. Dovecot has this anvil daemon, can it be used for that purpose? We use dovcot version 2.0.12 under Solaris 10, the pop3-login part of the configuration looking like that: service pop3-login { chroot = login client_limit = 0 drop_priv_before_exec = no executable = pop3-login extra_groups = group = idle_kill = 0 inet_listener pop3 { address = port = 110 ssl = no } inet_listener pop3s { address = port = 995 ssl = yes } privileged_group = process_limit = 0 process_min_avail = 0 protocol = pop3 service_count = 1 type = login user = $default_login_user vsz_limit = 64 M } Thanks, Jürgen -- Hochschulrechenzentrum der | Mail: Juergen.Obermann(a)hrz.uni-giessen.de Justus-Liebig-Universitaet | WWW: http://www.uni-giessen.de/obermann/ Heinrich-Buff-Ring 44 | Tel: 0641-99-13054 (0641-99-13001) D-35392 Giessen, Germany | Fax: 0641-99-13009

[Dovecot] ZFS Filesystem Quota under Solaris 10 and Sparc
by Jürgen Obermann 15 Jun '11

15 Jun '11

Hallo. Filesystem quotas used to work well under Solaris 9 and ufs filesystems on the Sparc platform even with two rules for the folders in the users home directories /home/group/user and the separate filesystem /var/mail holding the inboxes: plugin { quota = fs:Home-Verzeichnis:noenforcing quota2 = fs:INBOX:noenforcing:mount=/var/mail } Since we upgraded last year to Solaris 10 with zfs filesystems on our Sparc server still using a similar setup with separate filesystems for home directories and inboxes we have no working quota plugin anymore. Currently we use dovecot 2.0.13. Are there any plans or whishes to get the filesystem quota code working again under zfs and Solaris?

These folders should have per-user Seen flags, so I configured: namespace { type = public separator = . prefix = public. location = maildir:/var/mail/public:INDEX=%u/public subscriptions = no list = children } But this only seems to work with my account (presumably as I was the first one who touched the folder), all other users cannot change the "Seen" flags My home dir is set to /home/mail/harenber and there is a: mail# ls -l total 1162 -rwxrwxrwx 1 10001 wheel 4016 Jun 9 13:27 dovecot.index -rwxrwxrwx 1 10001 wheel 1125376 Jun 14 11:26 dovecot.index.cache -rwxrwxrwx 1 10001 wheel 2140 Jun 9 13:40 dovecot.index.log -rwxrwxrwx 1 10044 wheel 33792 Jun 9 13:28 dovecot.index.log.2 mail# pwd /home/mail/harenber/harenber/public/.fb8 (don't know why my username appears twice). which looks the same on some other account: mail# ls -l total 1380 -rw-rw-rw- 1 10002 wheel 4016 Jun 9 19:40 dovecot.index -rw-rw-rw- 1 10002 wheel 1364992 Jun 10 10:54 dovecot.index.cache -rwxrwxrwx 1 10114 wheel 16072 Jun 10 10:54 dovecot.index.log mail# pwd /home/mail/sandhoff/sandhoff/public/.fb8 The public folder looks like this: mail# pwd /var/mail/public/.fb8 mail# ls -l total 52 drwxrwxrwx 2 root wheel 512 Jun 9 13:05 cur -rwxrwxrwx 1 root wheel 54 Jun 9 13:11 dovecot-acl -rwxrwxrwx 1 root wheel 97 Jun 9 13:05 dovecot-keywords -rw-rw-rw- 1 10001 wheel 18513 Jun 9 13:27 dovecot-uidlist drwxrwxrwx 2 root wheel 23552 Jun 9 13:05 new -rwxrwxrwx 1 root wheel 0 Jun 9 13:05 subscriptions drwxrwxrwx 2 root wheel 512 Jun 9 13:05 tmp Does anybody see what I did (again) wrong?

[Dovecot] doveadm who: Please Headline to STDout, not to STDERR
by Denny Schierz 15 Jun '11

15 Jun '11

hi, I've created a small script to get a sum from the users and sessions (table username and table "#"), but it is annoying that the headline "username # proto (pids) (ips)" goes to STDERR, but the normal output to STDOUT. It would be nice, if both goes to the same STD :-) cu denny

[Dovecot] Timeout during APPEND
by martin f krafft 14 Jun '11

14 Jun '11

Dear list, I am running dovecot 1.2.15 on a Debian server. One user reports continuous problems synchronising her mailbox via IMAP (offlineimap, via SSH tunnel or SSL socket). It seems that she has a large, locally-created message, but the uplink bandwidth seems to be not enough to push it before dovecot times out the APPEND command. The error/exception happens inside offlineimap's Python imaplib2.py file: APPEND => no response after 30.0 secs I do not know the IMAP protocol all that well, but it seems to me like this is broken somewhere. Could you please help me figure out the problem? -- martin | http://madduck.net/ | http://two.sentenc.es/ "man sagt nicht 'nichts!', man sagt dafür 'jenseits' oder 'gott'." - friedrich nietzsche spamtraps: madduck.bogus(a)madduck.net

[Dovecot] SSL comunication problems with client side.
by Denis Iskandarov 14 Jun '11

14 Jun '11

I can get messages without SSL with no problems. but i need to setup server accept only SSL secured connections. I think my configuration is very proper, but cant find "obvious" problem. Postfix 2.3.3 + dovecot 2.0.13-1_129.el5 + PostfixAdmin 2.3.3 I made own CA. configured postfix and dovecot with same cert key ca. Same public cert i gave for client just converted it to PKCS#12. I cant undestand valid and invalid certs strings in long, they look same. You can check logs and config bellow. Also some other questions regarding SSL: 1. How to make client MUA (thunderbird) automatically retrieve certificate ? My thunderbird cant do it by itself so i'm importing mail cert by myself. 2. If i want to setup Roundcube/Squirrelmail webmail clients with TLS support (https) i have to provide them with same certificates as dovecot and postfix have. Or in this case i can use whatever certificate dedicated for with "virtualhost"? dovecot-deliver.log: Jun 13 13:26:42 imap-login: Info: Invalid certificate: unable to get certificate CRL: /C=GE/ST=Tbilisi/O=Caucasus Digital Network/OU=Mail Server/CN=mx.office.dev/emailAddress=hostmaster(a)office.dev Jun 13 13:26:42 imap-login: Info: Invalid certificate: unable to get certificate CRL: /C=GE/ST=Tbilisi/L=Tbilisi/O=Caucasus Digital Network/OU=Caucasus Digital Network/CN=Caucasus Digital Network/emailAddress=hostmaster(a)office.dev Jun 13 13:26:42 imap-login: Info: Valid certificate: /C=GE/ST=Tbilisi/L=Tbilisi/O=Caucasus Digital Network/OU=Caucasus Digital Network/CN=Caucasus Digital Network/emailAddress=hostmaster(a)office.dev Jun 13 13:26:42 imap-login: Info: Valid certificate: /C=GE/ST=Tbilisi/O=Caucasus Digital Network/OU=Mail Server/CN=mx.office.dev/emailAddress=hostmaster(a)office.dev Jun 13 13:26:42 auth: Info: PLAIN(?,192.168.0.11): Client didn't present valid SSL certificate Jun 13 13:26:42 auth: Info: LOGIN(?,192.168.0.11): Client didn't present valid SSL certificate Jun 13 13:26:42 auth: Info: PLAIN(?,192.168.0.11): Client didn't present valid SSL certificate Jun 13 13:26:42 imap-login: Info: Disconnected (client sent an invalid cert): method=PLAIN, rip=192.168.0.11, lip=192.168.0.31, TLS maillog.

[Dovecot] Sieve question
by Dhaval Patel 14 Jun '11

14 Jun '11

I have successfully setup Postfix -> Dovecot with virtual users and spam filtering with spamassassin. Now the last remaining part is for the user defined rules. Let me describe my environment and what I am trying to achieve. I have Postfix setup to call spamc and deliver to Dovecot according to the master.cf line below. -------------------------------------------------------------- dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/bin/spamc -u vmail -e /usr/lib/dovecot/deliver -d ${recipient} -------------------------------------------------------------- The emails get checked by Spamassassin and are delivered to the users's mailbox (/home/vmail/username). I use an actual username (dhav) and not email address (dhaval(a)example.com) Things are working fine with that. >From reading http://wiki.dovecot.org/LDA/Sieve I see that Sieve can do global and user specified filtering. So I am planning to put the following rule into the global script so spammy emails go to the user's INBOX.spam folder. -------------------------------------------------------------- require "fileinto"; if header :contains "X-Spam-Flag" "YES" { fileinto "spam"; } -------------------------------------------------------------- My first question is, where is this global script? Do I configure the "sieve_global_dir = /etc/dovecot/sieve/"? What about he filename? Most users will not need any additional rules. There are some users that do and I am having a difficult time figuring out how it would be setup. My second question is the following. Is there a way in the global script to check if there is a file called /etc/dovecot/sieve/username or /home/vmail/username/personal_sieve_script and include it? I was using maildrop before this and procmail before that so I apologies for sounding stupid if this is not how Sieve scripts work. I am by no means tied the methods I describe above. If anyone knows of a better way to achieve what I am trying to do, I would appreciate if you let me know of it. Thanks, Dhaval

[Dovecot] Version differences, trash, upgrade
by José Antonio Suarez Pinzón 14 Jun '11

14 Jun '11

Hello everybody, I have some basic questions: 1. how can I configure the auto-empty trash plugin for all users after 3 or 4 days (This is very important, regular users do not clean their trash, or are using blackberry and do not have an option to do it or simply, do not care about it) 2. difference between version 1.2.17 and latest 2 version of Dovecot, have the version 2 an automatic option for the trash thing? 3. me as a basic skilled user, how can I made the upgrade to version 2 without major risks, I mean I do not want to leave everybody on my server without mail. I am a novice in all of this stuff, so please excuse me if I am making dumb questions. Thanks in advance for your help. Information about my installation. # 1.2.17: /etc/dovecot.conf # OS: Linux 2.6.18-164.11.1.el5 x86_64 CentOS release 5.6 (Final) protocols: imap imaps pop3 pop3s plugin: quota: maildir quota_rule: Trash:ignore Kind Regards, José Antonio Suárez Pinzón Auge CS (+57 1) 812 7629 (+57) 300 618 0017

[Dovecot] Admin access to shared mailboxes

Having enabled shared mailboxes - is there a way to provide access to all users' mailboxes by a given user? Instead of having to manually provide ACL rights to every mailbox of every user? -- Daniel
