Merging maildirs
by Petter Gunnerud 28 Aug '15

28 Aug '15

Hi List How do I merge files from one maildir into another maildir? Long version: I've been using dovecot/postfix for a 12 user environment for several years, and today was the first time I ran into an issue I could not solve from reading the documentation. The server is gentoo running on esxi. A few times a year I've made a snapshot of the server and copied the files to my home esxi server as a full system backup. 5 days ago the internet connection at the office broke, and I decided to power on the last copy of the server at my home and change public dns so that users could access their new mails via webmail from this spare server. (I didn't allow imap through firewall.) Now the network at the office is back. DNS is updated so that mails are delivered to the office server again. But all the mails sent / received during those 5 days is only at my house. How can I merge those into the office server?I'd like to do this as a server administrator. I do not want to have each user forward the mails to them self from the temporarily webmail. I tried to just copy the mail files on my own account - like I did once when I used courier-imap, but that did not work with dovecot. I hope someone has an idea of how to solve this.

Hello, I'm using the Debian builds of dovecot-2.2 by S[r]us.

mailbox deletion is not replicated correctly
by Dennis Kuhn 27 Aug '15

27 Aug '15

i can't delete several folders at once. I have a folder structure like folder1/folder2/folder3 (we use slash as hierarchy separator). When i delete folder1 server1 executes the command correctly Apr 16 13:44:28 server1 dovecot: imap(d.kuhn(a)heinlein-support.de): Mailbox deleted: INBOX/Trash/folder1/folder2/folder3 Apr 16 13:44:28 server1 dovecot: imap(d.kuhn(a)heinlein-support.de): Mailbox deleted: INBOX/Trash/folder1/folder2 Apr 16 13:44:28 server1 dovecot: imap(d.kuhn(a)heinlein-support.de): Mailbox deleted: INBOX/Trash/folder1 but the replica server2 reverses the order: Apr 16 13:44:29 server2 dovecot: dsync-server(d.kuhn(a)heinlein-support.de): Mailbox deleted: INBOX/Trash/folder1 Apr 16 13:44:29 server2 dovecot: dsync-server(d.kuhn(a)heinlein-support.de): Mailbox deleted: INBOX/Trash/folder1/folder2 Apr 16 13:44:29 server2 dovecot: dsync-server(d.kuhn(a)heinlein-support.de): Mailbox deleted: INBOX/Trash/folder1/folder2/folder3 This creates the folder INBOX/Trash/folder1/folder2 on server2 again which replicates back to server1.

mail_log proposal: recipient
by Peter Chiochetti 27 Aug '15

27 Aug '15

As Timo seems to be on a committing spree; I'd like to propose that in the mail_log_fields the recipient would be available. Like probably many dovecot users, my MUAs save to Sent; so when grepping the log to learn etc. that would just be useful Kind regards -- peter

Duplicate folder names
by Paulo Matos 26 Aug '15

26 Aug '15

Hi, I have setup message filtering and for example, I might move a message which a given sender to folder special/. This folder is created and shows up twice in INBOX/special/ and special/. They are however exactly the same folder. If I subscribe to one I am automatically subscribed to the other and viceversa. Not too happy with this configuration. I have a feeling this is related to namespaces but I am not sure in which way to configure things in order to have only INBOX/special but not special/. How can I set this up. My current configuration is: $ dovecot -n # 2.2.18: /etc/dovecot/dovecot.conf # OS: Linux 4.1.0-x86_64-linode59 x86_64 Fedora release 22 (Twenty Two) ext4 auth_debug = yes auth_mechanisms = plain login digest-md5 cram-md5 auth_verbose = yes auth_verbose_passwords = yes default_internal_user = root imap_client_workarounds = delay-newmail tb-extra-mailbox-sep mail_debug = yes mail_location = maildir:/home/vmail/%d/%n/Maildir maildir_very_dirty_syncs = yes mbox_write_locks = fcntl namespace { inbox = yes location = prefix = INBOX. separator = . type = private } namespace inbox { location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } postmaster_address = pmatos protocols = imap quota_full_tempfail = yes service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-master { mode = 0600 user = vmail } user = $default_internal_user } ssl = required ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { args = uid=5000 gid=5000 home=/home/vmail/%d/%n allow_all_users=yes driver = static } protocol lda { auth_socket_path = /var/run/dovecot/auth-master deliver_log_format = msgid=%m: %$ log_path = /home/vmail/dovecot-deliver.log } protocol imap { mail_max_userip_connections = 100 } Regards, Paulo Matos

Hello folks, Any plans on implementing the PROXY protocol to allow Dovecot being behind a TCP proxy, and still logging the real IP address of the users ? See : http://blog.haproxy.com/haproxy/proxy-protocol/ Thanks !

Shared Mailboxes Not Visible

OK, gurus, I've spent the last 2 days crawling through all of the posts and web postings regarding shared folders, and I simply cannot get it to work.

sieve and managesieve are both working fine, have been for years. Now I want to add a sieve_after script: /etc/dovecot/conf.d/90-sieve.conf : plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_before = sieve_after = ~/sieve/personal.sieve sieve_subaddress_sep = + } I have compiled ~/sieve/personal.sieve to ~/sieve/personal.svbin, but it doesn't seem to be read.

Store ACL files within shared mailbox / rename shared folder problem
by Chris Laif 24 Aug '15

24 Aug '15

Hi. If $otheruser shares a mailbox to $myuser, my private index is stored in *my* Maildir, according to this template (from the dovecot docs): mail_location = maildir:%%h/Maildir:INDEXPVT=%h/Maildir/shared/%%u If $otheruser renames the shared mailbox, all my private mail flags (Seen) are lost because my mailclient couldn't find the private index anymore. Is there any way to store the private index within the shared mailbox? If $otheruser renames the mailbox, the index will be 'migrated' as well. Something like this: /data/mails/$otheruser/Maildir/.MagicSharedFolder/shared/$myuser.dovecot.index.pvt.log I see no way on how to do craft a INDEXPVT for this. Kind regards, Chris

plugin antispam sa-learn run program failed with exit code -1
by Guillaume Lakano - DOVECOT 24 Aug '15

Hello ! I've installed iRedMail on an Ubuntu Server 14.04.1 I'm not the only one on the iRedMail forum to have the problem, but the developpers of iRedMail doesn't found the problem and advice me to ask you directly. When I want to move an email directly to /Junk/ this not works. In Thunderbird, the error is : "[SERVERBUG] failed to send mail" In RoundCube, the error is : "Server Error: UID MOVE: failed to send mail ." But, if we firstly delete the email, then move the email from /Trash/ to /Junk/ this works.

IMAP Folder Mail Separator
by Alex 23 Aug '15

23 Aug '15

Hi, I have a fedora21 install with dovecot-2.2.18, and when creating a new subfolder with thunderbird, the actual folder name is "Folder1^Folder2" with a carat as a separator, instead of creating Folder2 in the Folder1 directory. Is this a thunderbird problem? I don't recall having this problem prior to upgrading to fedora21, so thought maybe it's a dovecot problem. Maybe the separator character is customizable? Thanks, Alex

migrating servers
by chris 23 Aug '15

23 Aug '15

Hi I am trying to migrate from a Centos dovecot 1.0.7 install to a debian dovecot 2.1.7 install. I thought simply replicating the maildirs would be fine (using rsync) but when I fetch mail from the new server using IMAP thunderbird wants to download all the messages again as duplicates. I searched the wiki over to see if I could find a solution and while it appeared I could use doveadm backup that seems to only work pushing changes from the new server to the old (wrong direction) and that program does not exist on the earlier version of dovecot on the old server. If I can be very blunt the documentation on the wiki assumes far too much knowledge from the reader. It is often hard to decipher exactly what is meant by many of the obtuse instructions. But that is an aside can anyone give me pointers on how to do this migration for all my users so they don't need to sort through hundreds of duplicated emails? Chris

Error: User initialization failed
by ＠lbutlr 19 Aug '15

OK, I obviously forgot something when setting up new user accounts (which I did via postfix admin to add them to the MySQL database): dovecot: lda(chance(a)example.com): Error: User initialization failed: Namespace '': Ambiguous mail location setting, don't know what to do with it: /usr/local/virtual/chance@ example.com (try prefixing it with mbox: or milder:) I have lots of mysql users defined and working, but do I need to manually create the mail store for new ones? (Sorry, it’s been quite a long time since I had to add accounts). -- You start a conversation you can't even finish it You're talkin' a lot, but you're not sayin' anything When I have nothing to say, my lips are sealed Say something once, why say it again?

logging into user mailboxes with admin credentials
by Noam Birnbaum 19 Aug '15

19 Aug '15

Hey folks, We are planning a migration away from Dovecot (sorry) to Google Apps and are trying to figure out how to migrate the contents of user mailboxes to the new provider. Normally we would use an IMAP migration tool to log into each user's mailbox on the old and new providers and transfer the data that way. However, there is no central directory service; all accounts are local. We have a large number of users and for both management and security reasons it's not feasible to compile a list of all IMAP passwords. Is there a way to log into user IMAP accounts on Dovecot using a central administrative credential? Thanks!

NFSv4 delegation
by brd 18 Aug '15

18 Aug '15

hi all, i'm managing a large installation of a dovecot cluster in director + NFS backend architecture and we are moving from NFSv3 to NFSv4. Our NFS server is a Netapp in clustered mode and reading technical specs of NFSv4 delegation feature it seems that enabling delegation in this type of dovecot architecture should bring great benefits: only one backend server access a specific mailbox at a time (even deliveries are managed by director hashing via LMTP) so the getattr rpc calls should decrease significantly while the risk of conflicting delegations is very low (impacting negatively on the benefits obtainable). Can anyone confirm this hypothesis? I've heard that the linux implementation of NFSv4 delegation is mature only for read delegation (and not yet for write delegation): is this true? And, if true, could this fact limit the benefits of activating NFS delegation feature? Best regards -brd

multiple messages per second to a single mailbox
by Chad M Stewart 18 Aug '15

18 Aug '15

Dovecot 2.2.18 on CentOS 6 I have a pair of servers setup with MySQL, Postfix, and Dovecot. Replication is setup and working between the two dovecot instances. The problem I'm running into is that a single mailbox receives a lot of messages, at times the rate is multiple messages per second. Delivery from Postfix to Dovecot is via tcp based LMTP. When I do 'ps -aef|grep lmtp|wc -l' I get 62 and does not appear to go higher than that. At the moment I have 4500 and 8300 messages queued on two Postfix instances waiting to deliver via LMTP to the same dovecot instance. Deliveries only happen via LMTP and only one of the two nodes actually gets the deliveries. What I'm seeing is very high load on the system (40) and queues building on the Postfix side. Replication is keeping up. Looking at the logs now I see anywhere from 4-7 messages per second delivered to this single mailbox. I would like to increase that rate a lot. These machines are VMs hosted on Xenserver 6.x. I have them setup with 8 vCPUs (2 sockets with 4 cores per socket), the dom0 machines have dual HBA connectors back to a SAN and have 128 CPUs and 256GB of RAM and are not taxed. I added a 2nd virtual disk that is used for storing mailbox data. It is ext4 and has noatime set during mount. /var is also mounted with noatime. The performance graphs in XenCenter show nearly all 8 vCPUs at about 50%, and the writes on the mailbox data disk are about 20%. iostat is showing mostly <5 for await times for the disks, though I do see a 10 now and again. I'm guessing that maybe I'm hitting a mailbox locking issue and not sure how to reduce the contention and thereby increase the delivery rate to this mailbox. -Chad

Syncing two mail servers?
by Knute Johnson 17 Aug '15

17 Aug '15

I currently have a mail server using Dovecot and sendmail. I was thinking I would like to have a backup of my mail and an additional server in case of hardware failure. Is it possible to run two identical or nearly identical server setups and sync the mail files between them? If it is possible, in general terms how would one go about this? Thanks, -- Knute Johnson

I am on CentOS 5 and 6, but I am building RPMs for our test and production servers. I recently built v2.2.18 and I decided to give it a try. (I run it with postfix - also just upgraded to 2.11.6.) The issue seems to not occur any more. I had already tested on two test servers, and I hoped someone could provide independent feedback before I decided to upgrade production servers. However, I now also upgraded our two production servers and things seem to be running smoothly. All the best, Nick

sieve-filter failure problems
by Jost Krieger 17 Aug '15

17 Aug '15

I use sieve-filter for postprocessing misclassified mail. For false positives I use the following script: require [ "variables", "include", "fileinto" ]; global [ "FORCENOSPAM", "ext", "ext1" ]; set "FORCENOSPAM" "YES"; fileinto "JUNK-PRENOUCE"; if header :matches "Delivered-To" "*+*@*" { set "ext" "${2}"; set "ext1" "${2}"; } include :personal "production"; FORCENOSPAM suppresses the spam handling and the Delivered-To stuff tries to regenerate envelope info. This is my crontab entry: 1-57/4 * * * * cd ~kriegjcb; /usr/local/dovecot/bin/sieve-filter -v -e -W -u kriegjcb -m Spam/U0-failed ~kriegjcb/sieve/nospamfilter.sieve Spam/U0 Most things work fine, but a few of my rules will try to forward mail. This will fail and my idea was I handle this manually from the folder Spam/U0-failed. Unfortunately the mail will arrive there but will also be left in the source folder Spam/U0 and will be processed again every 4 minutes ... This is probably not intentional?

Duplicate mails with pop3 + dsync replication
by Wolfgang Hennerbichler 17 Aug '15

17 Aug '15

Hi, When I enable (and it only happens when it is actually running) replication over TCP my users get duplicate mails via pop3. Here’s what happens: * User gets mail * Mail appears in (Maildir) new/ folder on both replicas * user retrieves mail (retr), calls dele. Mail still exists in new/ folder on both replicas. * user runs retr (and gets the duplicate) and dele a second time, the mail is actually removed. If I disable replication this behaviour goes away. I use dovecot from debian stable resources. Any help would _really_ be appreciated. I found one german thread that dealt with the same problem, but no solution for it (http://www.dovecot-buch.de/mailingliste/pop3-fehler-bei-delete-und-dsync-re…) wogri # dovecot --version 2.2.13 # dovecot -n # 2.2.13: /etc/dovecot/dovecot.conf # OS: Linux 3.16.0-4-amd64 x86_64 Debian 8.0 ext4 auth_verbose = yes doveadm_password = XXX first_valid_gid = 113 first_valid_uid = 108 last_valid_gid = 113 last_valid_uid = 108 mail_gid = dovecot mail_location = maildir:/var/mail/%n mail_plugins = quota fts fts_lucene virtual notify replication mail_temp_dir = /var/lib/dovecot/tmp mail_uid = dovecot namespace { list = children location = virtual:/var/mail/%n/virtual prefix = virtual. separator = . } namespace inbox { inbox = yes list = yes location = mailbox "Deleted Messages" { auto = subscribe special_use = \Trash } mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { auto = no special_use = \Sent } mailbox Spam { auto = subscribe special_use = \Junk } [48/4646] mailbox Trash { special_use = \Trash } prefix = separator = . subscriptions = yes type = private } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { default_language = de fts = lucene fts_lucene = whitespace_chars=@. mail_replica = tcp:172.16.1.1:12345 quota = maildir:User quota quota_rule = *:storage=4G quota_rule2 = Trash:storage=+100M quota_rule3 = Spam:ignore quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=80%% quota-warning 80 %u sieve = /etc/sieve/%n.sieve sieve_default = /etc/sieve/default.sieve sieve_dir = ~/sieve sieve_extensions = +editheader } postmaster_address = postmaster(a)wogri.at protocols = " imap lmtp pop3" service aggregator { fifo_listener replication-notify-fifo { user = dovecot } unix_listener replication-notify { user = dovecot } } service doveadm { inet_listener { port = 12345 } } service imap { process_limit = 1024 } } service lmtp { inet_listener lmtp { address = 127.0.0.1 port = 2003 } user = dovecot } service managesieve-login { inet_listener sieve { port = 4190 } service_count = 1 } service pop3 { process_limit = 1024 } service quota-warning { executable = script /usr/local/sbin/quota-warning.sh unix_listener quota-warning { user = dovecot } user = dovecot } service replicator { process_min_avail = 1 unix_listener replicator-doveadm { mode = 0600 } } ssl = required ssl_cert = </etc/exim4/server.cert.pem ssl_key = </etc/exim4/server.key.pem userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocol lmtp { mail_plugins = quota sieve virtual notify replication } protocol lda { mail_plugins = quota fts fts_lucene virtual notify replication sieve } protocol imap { mail_max_userip_connections = 50 mail_plugins = quota fts fts_lucene virtual notify replication imap_quota }
