more than two way replication
by djk 02 Sep '15

02 Sep '15

Is there anyway of replicating between more than one other instance of Dovecot. I have bidirectional replication working successfully and it seems to be reliable. I would like to replicate from one or more of these instances to one other. Is this possible? Dirk

imap segfaults when using antispam plugin, and moving mail to an 'unsure' folder.
by Andrew McN 02 Sep '15

02 Sep '15

I put up a question on serverfault first, which has the details, including a stack trace: http://serverfault.com/questions/713687/dovecot-antispam-error-storing-mail . Details also copied below. Is this a known bug? If I built dovecot from source rather than using the Ubuntu 14.04 packages, would I expect that to help? Are there any configuration details that might be relevant? (dovecot -n output shown Any help much appreciated. Andrew McNaughton Details on the serverfault page repeated below, plus a little more. ----------------------------------------------------- Ubuntu 14.04.3 x86_64 Running inside lxc-docker 1.7.0 dovecot-imapd 1:2.2.9-1ubuntu2 dovecot-antispam 2.0+20130822-2build1 Filesystem is via docker, so aufs is involved, and under that on the host systems is ext4 ----------------------------------------------------- I know mail is not supposed to be moved into a mailbox of type 'unsure'. The server should refuse this action.

doveadm-server hangs with 100% cpu usage
by Dennis Kuhn 02 Sep '15

02 Sep '15

we have some replication issues. From time to time a doveadm-server process takes 100% cpu in the state recv_mailbox_tree_deletes on the replica. The process runs forever until it is manually killed. Strace on this process doesn't show anything. Sometimes we have several doveadm-server processes in this state, all for the same account, all with 100% CPU Load. The logfile on the master says: Error: Timeout during state=recv_mailbox_tree Error: dsync(dobby5.heinlein-support.de): I/O has stalled, no activity for 600 seconds My workaround is to delete the user directory on the replica so that the whole account is replicated again. This solves the problem for this specific account. The dovecot version is 2.2.15 on the master and 2.2.16 on the replica.

Moving mails from shared folder to shared folder doesn't work
by Peer Heinlein 02 Sep '15

02 Sep '15

Hi, having the attached configuration with Dovecot 2.2.9, Dovecot's crashing when moving a mail from a shared folder into another shared folder. Moving that mail into a "real" folder of the user or moving that mail from a real folder into the shared folder is always working. But moving from a shared folder into a shared folder doesn't work.

Single Instance Storage after the fact
by Joe Beaubien 02 Sep '15

02 Sep '15

Hi everyone, I tried to find info about this online, but I couldn't find anything talking specifically about what I am trying to accomplish. I am sending and receiving the same attachments pretty often and as a result my email accounts are growing much more rapidly than I would like. *My goal* is to set up a second instance of Dovecot with SIS enabled and transfer everything over to this new Dovecot setup. I was thinking of simply running a dsync backup from the old instance and then a dsync backup -R on the new instance with SIS. Would this effectively create a new set of mailboxes without attachments (and a new folder full of attachments)? If not, can someone point me to information on how to accomplish this? Best regards, Joe B.

Post-migration questions
by Grant 29 Aug '15

29 Aug '15

I just migrated from courier-imap to dovecot and dovecot is a lot faster. My only client is webmail on the same server as dovecot. Max ~10 users. Should I still run imapproxy like I did with courier? Does dovecot periodically empty the trash folder like courier does? I reduced the number of processes courier was running to save RAM and improve performance. Are there any performance tweaks I should consider for dovecot? - Grant

IMAP hibernate feature committed
by Timo Sirainen 29 Aug '15

29 Aug '15

http://hg.dovecot.org/dovecot-2.2/rev/64c73e6bd397 Today I finally committed the "imap-hibernate" feature that I first started developing about a year ago (and had been thinking about for several years before that). The main purpose here is to reduce the number of imap processes and the amount of memory they use by moving IDLEing connections into imap-hibernate processes where they are waiting for something to happen (changes to the mailbox or IMAP client to do something). Mailbox changes are noticed only if inotify/kqueue is enabled, so without them the hibernation feature won't work well. For now only the IMAP connections that are in IDLE can be hibernated. In theory non-IDLEing connections could also be hibernated, but the main problem here is that if EXPUNGEs can't be sent at the time the hibernation is over, the current code can't handle it. They would require recreating a view that contains such expunged messages, which could be possible with some extra work. Some IMAP extensions aren't supported yet: - NOTIFY: This would just need to import/export the NOTIFY state. Also hibernation could be done at any time if VANISHED replies could be sent to the selected mailbox. - SEARCH=CONTEXT: A bit more troublesome extension to support. I'm not sure how big the trouble would be. It's rarely used though. - COMPRESS: The [de]compression code would need to be moved to login process instead of being done in imap-compress plugin. This would be a larger change, although it's also useful for various other purposes. The hibernation can be enabled for now simply by setting imap_hibernate_timeout setting to non-zero, which controls how long to wait after client has issued IDLE (and nothing happens) until the process hibernates. Some future work might include: - Moving the hibernation all the way to the first Dovecot proxy layer to avoid the need for imap-hibernate process at all. (Also moving the COMPRESS handling all the way there.) - Dynamically adjusting when the client should be hibernated instead of just a fixed imap_hibernate_timeout setting. Especially try to avoid such a situation where the hibernation is almost always terminated soon after it started. Although that probably is unlikely, so maybe not worth the trouble to prevent.. - Hibernation could be used to control the load of the server. If it's running too slow or if there are already too many imap processes, some of the connections could be moved to hibernation stage. Or just kept in hibernation for a while longer even after the imap process would normally be recreated (e.g. wait for several minutes before reporting new emails, or several seconds before replying to DONE). - The EXPUNGE/VANISHED and FETCH FLAGS replies aren't sent asynchronously, but instead fully buffered to the output buffer. This works as long as the list of changes after hibernation isn't huge, but otherwise it's wasting a lot of memory. - Maybe support non-inotify/kqueue change notifications from lib-storage. This could be complicated though to do efficiently. Or a simple way would be to just send a UDP or UNIX datagram packet on all changes to all the imap-hibernate processes and see if anybody cares about those. I'm not sure how efficient that would be.

Dovecot proxy and password scheme updating
by efs efefsfse 28 Aug '15

28 Aug '15

Hello, I run a dovecot proxy (which is doing authentification itself) and a dovecot backend on separate boxes. I want to change the actual password scheme. Since postlogin scripting is not supported by proxies and %w variable is not forwaded to dovecot backend is there any way that I can update the password scheme with my current setup ? Thanks in advance.

Allow delivery to existing accounts only with LDAP and static
by Miloslav Hůla 28 Aug '15

28 Aug '15

Hi, we are using LDAP binding as a passdb, and static with allow_all_users=yes as an userdb. Works fine, but problem is, Maildirs are created for non-existent accounts too. We would like to prevent it. The LDAP binding does not supporta user lookups. Is the correct way to use checkpassword as a passdb before LDAP, check for account existency here and: result_success=continue result_failure=return-fail ? Thank you, regards, Miloslav

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.

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

sieve_after seems to ignored ?
by Per Jessen 25 Aug '15

25 Aug '15

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. Any hints? thanks Per Jessen -- Per Jessen, Zürich (17.2°C) http://www.hostsuisse.com/ - dedicated server rental in Switzerland.

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

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.

Delivering email to Maildir PreINBOX

Hi all, I have a running dovecot with: $ 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 } I started to filter my email with imapfilter running on the same host as dovecot. I would therefore like to deliver email to a folder called PreINBOX so that imapfilter then sorts the email and ends up delivering only the useful email to INBOX. How can I change the name of the inbox dovecot delivers to? Best, -- Paulo Matos
