[Dovecot] Great time savings backing a mdbox versus Maildir
by Javier Miguel Rodríguez 09 Feb '11

09 Feb '11

Hello I am writing to this mailing list to thanks Timo for dovecot 2 & mdbox. We have almost 30.000 active users and our life was sad with Maildir & backup: 24 hours for a full backup with bacula (zlib enabled maildirs, 1.4 TB). After switching to mdbox, the backup time is under 12 hours ! Instead of backing 17 millions files, with mdbox our backup is only of 1 million files, and that speeds up a lot the backup operation. Timo, here you have detailed info about the bacula backup jobs, you can use them in the wiki if you desire. If you need aditional info (hardware specs, dovecot config, etc) I can share it. *Maildir:* |//Job: Backup_Linux_buzon_us.2011-01-21_19.03.26_38 Backup Level: Full Client: "buzon_us" 2.0.3 (06Mar07) x86_64-redhat-linux-gnu,redhat,Enterprise release FileSet: "Full Buzon" 2011-01-21 19:03:26 Pool: "Pool_Linux_Buzones_US" (From Job resource) Catalog: "MyCatalog" (From Client resource) Storage: "File" (From command line) Scheduled time: 21-ene-2011 19:03:20 Start time: 21-ene-2011 19:03:29 End time: 22-ene-2011 19:46:45 Elapsed time:*1 day 43 mins 16 secs* Priority: 10 FD Files Written: 16,903,801 SD Files Written:*16,903,801* FD Bytes Written: 1,445,943,227,706 (1.445 TB) SD Bytes Written: 1,448,983,971,450 (1.448 TB) Rate:*16247.3 KB/s* Software Compression: None VSS: no Encryption: no Accurate: no Volume name(s): Buzones_US_2 Volume Session Id: 26 Volume Session Time: 1295511704 Last Volume Bytes: 1,450,628,892,676 (*1.450 TB*) Non-fatal FD errors: 0 SD Errors: 0 FD termination status: OK SD termination status: OK Termination: Backup OK//| *mdbox with mdbox_rotate_size=10m:* |Build OS: x86_64-redhat-linux-gnu redhat Enterprise release JobId: 3587 Job: Backup_Linux_buzon_us.2011-02-07_08.13.52_53 Backup Level: Full (upgraded from Incremental) Client: "buzon_us" 2.0.3 (06Mar07) x86_64-redhat-linux-gnu,redhat,Enterprise release FileSet: "Full Buzon" 2011-01-21 19:03:26 Pool: "Pool_Linux_Buzones_US" (From Job resource) Catalog: "MyCatalog" (From Client resource) Storage: "File" (From command line) Scheduled time: 07-feb-2011 08:13:44 Start time: 07-feb-2011 08:13:54 End time: 07-feb-2011 19:43:50 Elapsed time:*11 hours 29 mins 56 secs* Priority: 10 FD Files Written:*1,148,780* SD Files Written: 1,148,780 FD Bytes Written:*1,537,062,152,773 (1.537 TB)* SD Bytes Written: 1,537,218,147,402 (1.537 TB) Rate:*37130.7 KB/s* Software Compression: None VSS: no Encryption: no Accurate: yes Volume name(s): Buzones_US_4|Buzones_US_5 Volume Session Id: 101 Volume Session Time: 1296724657 Last Volume Bytes: 438,873,898,586 (438.8 GB) Non-fatal FD errors: 0 SD Errors: 0 FD termination status: OK SD termination status: OK Termination: Backup OK| Regards Javier de Miguel University of Seville

[Dovecot] converting from maildir to mdbox ?
by Jan-Frode Myklebust 08 Feb '11

08 Feb '11

I´m considering moving from maildir to mdbox, but don´t quite see how I should do the conversion with minimal downtime. Our userdb is ldap, and the we use this setting to point to the users maildirectory: user_attrs = mailMessageStore=mail=maildir:%$:INDEX=/indexes/%1u/%1.1u/%u,mailQuota=quota_rule=*:storage=%$ i.e. every user has a "mailMessageStore" attribute in LDAP that points to his INBOX. Any ideas for how we can migrate user by user to mdbox? Can we add a mailboxFormat attribute to LDAP, and somehow get that used in the user_attrs lookup ? Ideally have it default to maildir if not set, so that the current setup isn´t changed and only migrated users are affected. Or should we be keeping the mailboxFormat as a prefix in all mailMessageStore strings ? -jf

[Dovecot] How to recover a mail box from an assertion failure
by Michael Durket 08 Feb '11

08 Feb '11

I'm running Dovecot version 1.2.11 and getting this assertion error on a user's mail: Panic: file /home/durket/dovecot-1.2.11/src/lib-index/mail-transaction-log-view.c: line 290 (mail_transaction_log_view_set): assertion failed: (min_file_seq != max_file_seq || max_file_seq != view->head->hdr.file_seq || max_file_offset != (uoff_t)-1 || min_file_offset <= view->head->sync_offset) I realize that there are newer releases of Dovecot (that even may fix this bug) but what I need to know is if there's anything I can do (like having Dovecot recreate indexes or whatnot) that will recover the user's mail (short of having to reconstruct it from backups).

[Dovecot] Auto rebuild indexes?

Here's an easy question for you. I'm restoring some emails from a backup. Do I need to delete or otherwise manually rebuild the indexes? dovecot.index.cache dovecot.index.log dovecot-uidlist Or will Dovecot itself detect that something is amiss and handle it on first folder access?

hallo, I have running dovecot 2.0.9. I want to deliver mail with rcipient prameter "-", we spoked about that at thread "LMTP with address extension" and after your patch and version 2.0.8 that works. But now, there's an another much greater problem. No mails to adresses, which domain-part contains an "-" sign wil be delivered (i.e. test(a)aku-punkt-berlin.de) lmtp is looking about the user "test@aku" instead of "test(a)aku-punkt-berlin.de" and the following logentries appears: Feb 3 10:46:36 vserver08 dovecot: auth: Debug: sql(test@aku): SELECT '/var/vmail/' || maildir as home, '5000' AS uid, '5000' AS gid, '*:bytes=' || quota as quota_rule FROM mailbox WHERE username = 'test@aku' and active = true Feb 3 10:46:36 vserver08 dovecot: auth: sql(test@aku): Unknown user Greatings Christoph

[Dovecot] dovecot: imap-login: Error: net_connect_unix(imap) failed: Resource temporarily unavailable
by Kurt Hockenbury 08 Feb '11

08 Feb '11

We recently switched over mail servers to one running dovecot and postfix on RedHat Enterprise 6. The mail store is NFS on a NetApp filer, the index files are on local disk. We have about 6000 total active users, though not all of them access the system at the same time. All goes well for a while, then we start seeing errors like this in the log: dovecot: imap-login: Error: net_connect_unix(imap) failed: Resource temporarily unavailable imap-login: Internal login failure (auth failed, 1 attempts) And at this point, users can't log in. I don't know what Resource dovecot is running out of. The machine is a 12-core Xeon 2.27Ghz, with 24GB RAM. I have removed the 1024 nproc limit in /etc/security/limits.d/90-nproc.conf, and upped the nproc and nofile limits to 16384 and 65535 respectively, both in limits.conf, as well as adding ulimit statements in /etc/init.d/dovecot (belt and suspenders). I have tried adjusting dovecot.conf, but I'm obviously missing something. dovecot -n follows: # 2.0.beta6 (3156315704ef): /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-71.14.1.el6.x86_64 x86_64 Red Hat Enterprise Linux Server release 6.0 (Santiago) auth_master_user_separator = * auth_mechanisms = plain login default_client_limit = 5000 default_process_limit = 5000 disable_plaintext_auth = no mail_fsync = always mail_gid = 501 mail_location = maildir:~/Maildir:INDEX=/var/indexes/%n mail_nfs_storage = yes mail_plugins = quota mail_uid = 501 passdb { args = /etc/dovecot/passwd.masterusers driver = passwd-file master = yes pass = yes } passdb { args = /etc/dovecot/dovecot-ldap.conf driver = ldap } plugin { quota = maildir:User quota quota_rule = *:storage=200M } service auth { client_limit = 32768 unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } user = root } service imap-login { process_min_avail = 12 service_count = 0 } service pop3-login { service_count = 0 } shutdown_clients = no ssl_cert = </etc/pki/postfix/certs/nexus.pem ssl_key = </etc/pki/postfix/private/nexus_key.pem userdb { args = /etc/dovecot/dovecot-ldap.conf driver = ldap } protocol imap { mail_plugins = $mail_plugins imap_quota } Thanks, -Kurt Hockenbury

[Dovecot] vpopmail passdb deadlock if tcprules binary is missing
by Teodor Milkov 07 Feb '11

07 Feb '11

Hello, I've just found that if vpopmail is compiled with --enable-roaming-users=y, but tcprules binary is missing there is kind of denial of service situation, which is not very obvious for debugging. I know this is result of misconfiguration and I suppose this is more of a vpopmail() bug, but it is somewhat hard to debug and causes greater harm to dovecot long running auth process than vpopmail's short living vchkpw process. Symptoms -------- Login to dovecot imap takes very long time. There are auth processes in D state: USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 9873 0.0 0.0 2884 1396 ? D 14:04 0:00 dovecot/auth -w root 11292 0.0 0.0 2884 1396 ? S 14:25 0:00 \_ dovecot/auth -w Cause ----- When new user has to be authenticated from vpopmail, the sequence of events goes something like this: * libexec/dovecot/auth -w process is doing the authentication (passdb-vpopmail.c) * passdb-vpopmail.c: at some point user is authenticated and open_smtp_relay() is called * vpopmail.c: open_smtp_relay() gets a write lock on ~vpopmail/etc/open-smtp.lock adds new IP to ~vpopmail/etc/open-smtp and calls update_rules() etc. to rebuild the tcp.cdb file * vpopmailc: tcprules_open() is called and it fork()s and tries to execv() tcprules * if tcprules is not found, execv() fails silently, and we are left with a forked libexec/dovecot/auth instance, which runs all over again up to the open_smtp_relay() point where it tries to obtain write lock on ~vpopmail/etc/open-smtp.lock again (it is already locked by parent) Hope this helps someone.

[Dovecot] maildrop and multi-dbox
by Manfred Lotz 07 Feb '11

07 Feb '11

Hi there, I'm using Dovecot 2.0.9-1 under Arch Linux. Currently, I have Maildir configured, and I move all my emails into dovecot by using this sequence: 1) cron starts fetchmail periodically under user manfred to collect my mails from various email accounts. 2) In ~/.fetchmailrc I have configured /usr/bin/maildrop as MDA. 3) In ~/.mailfilter (used by maildrop) I have extensive filtering in place and call bogofilter (by using xfilter) to classify spam mails. This works fine so far. Now I'd like to migrate to dovecot's new format multi-dbox. My question now: Is it correct that then I cannot longer use maildrop and would need to switch do dovecot-lda? -- Thanks, Manfred

[Dovecot] Dovecot Or Debian, Boot-Time Error "Can't assign requested address"
by Sabahattin Gucukoglu 06 Feb '11

06 Feb '11

Hi all, I have a really weird problem, which for now I have solved by just binding to the IPv6 wildcard address "::". Using the latest packages from Debian unstable (1.x series), I set up a tunnel with tunnelbroker.net for IPv6. I assign two of the delegated addresses in my /48 using IP aliases in /etc/network/interfaces to my ethernet interface (eth0 and eth0:1). All other servers start and run, binding to the primary address (eth0) assigned. The packet forwarder is not necessary, so it isn't turned on using sysctl. But Dovecot will only start if I launch it using the init script after boot. Until then, in syslog there is always: Fatal: listen(2001:470:xxxx::1): Can't assign requested address Anybody have the slightest clue what's going on here? Debian bug, or Dovecot? I suspect some problem with initscript order, yet inspection shows no apparent problem; network starts up before services. Very, very odd. Cheers, Sabahattin

[Dovecot] Splitting up mail_location setting?
by Timo Sirainen 06 Feb '11

06 Feb '11

mail_location setting has started becoming a bit bloaty. I'm not actually even sure why I've kept adding more parameters to it rather than just adding new settings. It's also caused confusion, because people try things like: mail_location = mbox:/var/mail/%u mail_location = mbox:INBOX=/var/mail/%u Although the first one has been giving ok enough error message for a long time now and the second one also will give in v2.0.10, it still would be nicer if there wasn't any need for such confusion at all. The settings could instead be: mail_format = mbox mail_inbox_path = /var/mail/%u Then Dovecot could complain about mail_root_path being empty, which would be more understandable.. The mail_location setting itself would keep working probably forever for backwards compatibility (and also in some setups it would be difficult to split it when it comes from LDAP/SQL), although some of its parameters could maybe be dropped after a while (SUBSCRIPTIONS, DIRNAME, MAILBOXDIR). So if you did e.g.: mail_location = mbox:~/mail:INBOX=/var/mail/%u mail_root_path = ~/mail2 The result would be same as mbox:~/mail2:INBOX=/var/mail/%u. Although this can also result in probably unwanted situation: mail_location = mbox:~/mail:INBOX=/var/mail/%u mail_format = maildir mail_root_path = ~/Maildir Now the result would be maildir:~/Maildir:INBOX=/var/mail/%u. This can be avoided by setting mail_inbox_path="" explicitly. Or the other way around: mail_inbox_path = /var/mail/%u mail_location = maildir:~/Maildir:INBOX= Without the INBOX= the mail_inbox_path would be in use. Below are the setting names I thought about using: a) mail_location = maildir:~/Maildir:INBOX=~/Maildir/.INBOX:INDEX=~/indexes:CONTROL=~/control:LAYOUT=fs:SUBSCRIPTIONS=courier-subscriptions mail_format = maildir mail_root_path = ~/Maildir mail_inbox_path = ~/Maildir/.INBOX mail_index_path = ~/indexes mail_control_path = ~/control mail_directory_layout = fs mail_subscriptions_fname = courier-subscriptions b) mail_location = mdbox:~/mdbox:ALT=/alt/%u:LAYOUT=fs:DIRNAME=dbox-Mails:MAILBOXDIR=mailboxes mail_format = mdbox mail_root_path = ~/mdbox mail_alt_path = /alt/%u mail_dir_name = dbox-Mails mail_mailboxes_dir_name = mailboxes Thoughts?

No, but it is pretty simple using latest everything (well, Debian squeeze).. Basically from scratch.. Notice this also sets up NTLM, which is supported by many roaming devices (ie phones). 1) Put this or similar in /etc/samba/smb.conf [global] workgroup = $NT_WORKGROUP$ realm = $REALM$ security = ads kerberos method = secrets and keytab 2) Confirm that hostname gives an unqualified name and hostname -f gives a fully qualified name.

[Dovecot] Best filesystem?
by Monika Janek 05 Feb '11

05 Feb '11

Hi everyone! What's the best filesystem to use for the mail spool? I'm debating between Debian with xfs or FreeBSD with zfs. I'm not sure which way to go. I'm migrating from cyrus. I have about 50 users so it's not a large setup. Cheers! Monika -- Monika Janek Systems Administrator, Side Effects Software Toronto, Ontario Canada 416-504-9876 x207 www.sidefx.com

[Dovecot] Question about managing multiple domains
by Sergio Moscoso 04 Feb '11

04 Feb '11

Actually we have configured a server (postfix,dovecot,mysql) with multiple domains, but the problem resides in that we don't want to login via POP3 using "user@domain" just using "user", because we'll migrate our actual platform (Qmail) to dovecot. Our users are logging to their mail boxes, using only user name. We want to ask if that's posible to use a function like a "vipmap" in qmail, that allow to map an IP address to a domain. We're using the dovecot 1.0.7, the configuration shows as follows: 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: 100 mail_location: maildir:~/Maildir/ mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 imap_client_workarounds(default): delay-newmail outlook-idle netscape-eoh imap_client_workarounds(imap): delay-newmail outlook-idle netscape-eoh imap_client_workarounds(pop3): outlook-idle pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: username_format: %Lu passdb: driver: sql args: /etc/dovecot-mysql.conf userdb: driver: static args: uid=101 gid=102 home=/home/vmail/%d/%n We'll apreciate your response, 'cause we coulnd't find information about this issuet and we didn't to find any clue that shows how can realize it.

[Dovecot] EUID not changing when delivering to a mailbox
by rastik＠tereus.eu 04 Feb '11

04 Feb '11

Hello, I've set up virtual mailboxes and I'm using one uid/gid pair (mail/mail) to deliver almost all messages. Some accounts I'd like to have accessible by local Linux accounts as well, so postfix is delivering them using separate uids (gid stays the same). But I run into a problem when dovecot auth correctly fetches uid/gid from MySQL database, but still uses general mail uid to access the mailbox instead of user uid. This is what I have in dovecot log: dovecot: auth(default): client in: AUTH 1 PLAIN service=imap secured lip=myipaddr rip=myipaddr lport=143 rport=55513 dovecot: auth(default): client out: CONT 1 dovecot: auth(default): client in: CONT<hidden> dovecot: auth-worker(default): sql(joe(a)mydomain.com,myipaddr): query: SELECT CONCAT('/var/mail/', maildir) AS userdb_home, username as user, password, CONCAT('*:bytes=', quota) AS userdb_quota_rule, uid, gid FROM mailbox WHERE username = 'joe(a)mydomain.com' AND active = 1 dovecot: auth(default): client out: OK 1 user=joe(a)mydomain.com uid=1000 gid=12 dovecot: auth(default): master in: REQUEST 11 17252 1 dovecot: auth(default): prefetch(joe(a)mydomain.com,myipaddr): success dovecot: auth(default): master out: USER 11 joe(a)mydomain.com home=/var/mail/mydomain.com/joe/ quota_rule=*:bytes=-1 dovecot: imap-login: Login: user=<joe(a)mydomain.com>, method=PLAIN, rip=myipaddr, lip=myipaddr, TLS dovecot: IMAP(joe(a)mydomain.com): opendir(/var/mail/mydomain.com/joe/Maildir) failed: Permission denied (euid=8(mail) egid=12(mail) missing +r perm: /var/mail/mydomain.com/joe/Maildir) dovecot: IMAP(joe(a)mydomain.com): stat(/var/mail/mydomain.com/joe/indexes/.INBOX) failed: Permission denied (euid=8(mail) egid=12(mail) missing +x perm: /var/mail/mydomain.com/joe/indexes) dovecot: IMAP(joe(a)mydomain.com): file_dotlock_create(/var/mail/mydomain.com/joe/Maildir/dovecot-uidlist) failed: Permission denied (euid=8(mail) egid=12(mail) missing +w perm: /var/mail/mydomain.com/joe/Maildir) dovecot: IMAP(joe(a)mydomain.com): opendir(/var/mail/mydomain.com/joe/Maildir/new) failed: Permission denied (euid=8(mail) egid=12(mail) missing +r perm: /var/mail/mydomain.com/joe/Maildir/new) dovecot: IMAP(joe(a)mydomain.com): stat(/var/mail/mydomain.com/joe/indexes/.INBOX) failed: Permission denied (euid=8(mail) egid=12(mail) missing +x perm: /var/mail/mydomain.com/joe/indexes) dovecot: IMAP(joe(a)mydomain.com): file_dotlock_create(/var/mail/mydomain.com/joe/Maildir/dovecot-uidlist) failed: Permission denied (euid=8(mail) egid=12(mail) missing +w perm: /var/mail/mydomain.com/joe/Maildir) ricola dovecot: IMAP(joe(a)mydomain.com): opendir(/var/mail/mydomain.com/joe/Maildir/new) failed: Permission denied (euid=8(mail) egid=12(mail) missing +r perm: /var/mail/mydomain.com/joe/Maildir/new) dovecot: IMAP(joe(a)mydomain.com): Disconnected: Logged out bytes=171/775 My configuration is: # 1.2.16: /etc/dovecot/dovecot.conf # OS: Linux 2.6.36-hardened-r6 x86_64 Gentoo Base System release 2.0.1 ext4 listen: *, [::] ssl_cert_file: /etc/ssl/dovecot/server.pem ssl_key_file: /etc/ssl/dovecot/server.key login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login first_valid_uid: 8 last_valid_uid: 1999 first_valid_gid: 12 last_valid_gid: 12 mail_privileged_group: mail mail_uid: 8 mail_gid: 12 mail_location: maildir:/var/mail/%d/%n/Maildir/:INDEX=/var/mail/%d/%n/indexes lda: postmaster_address: postmaster(a)mydomain.com mail_plugins: quota auth default: mechanisms: plain login user: nobody verbose: yes debug: yes passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: prefetch userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: mail group: mail I'm not sure if I got the concept correctly, but I was expecting that dovecot will use uid from the database.

[Dovecot] Dovecot 2 multiple address/port binding
by Thomas Hummel 04 Feb '11

04 Feb '11

Hello, Sorry, I know the topic has been talked about already but I searched the archives and I'm still unsure of the proper way to have dovecot (imap-login) listen to several addresses and/or several ports. 1. how do I translate dovecot-1 protocol imap { listen = xx.xx.xx.xx:143 yy.yy.yy.yy:143 ssl_listen = xx.xx.xx.xx:993 yy.yy.yy.yy:939 } I started by service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } but I don't know if I should add multiple "address" lines, other inet_listener {} sections, or multiple address on the same "address" line. 2. besides I don't know if it's possible to listen on the same address to several ports for the same "subservice" : for instance could I have an inet_listener imap {} listen on zz:zz:zz:zz:port1 and zz:zz:zz:zz:port2 ?

[Dovecot] Ldap and secondary PosixGroups
by Matthieu Ambrosy 04 Feb '11

04 Feb '11

Hello all, I'm using "Pam Ldap" for my users (Debian Lenny). getent passwd : *m.ambrosy:x:2000:100:m.ambrosy:/home/m.ambrosy:/bin/bash* getent group : *l_admin:*:2000:m.ambrosy l_personnel:*:2001:m.ambrosy l_mail:*:2003:m.ambrosy* As you can see, in LDAP, user "m.ambrosy" (PosixAccount) is defined with gidNumber = 100 (local group "users") and uidNumber = 2000. Furthermore this user belongs to 3 secondary Ldap PosixGroup (l_admin 2000, l_personnel 2001, l_mail 2003). If /var/mail belongs to the primary group (100), no problem. If /var/mail belongs to l_mail (2003) : *mkdir(/var/mail/m.ambrosy) failed: Permission denied (euid=2000(m.ambrosy) egid=100(users) missing +w perm: /var/mail, euid is not dir owner* In fact, Dovecot seems to not see secondary groups for my user. It just checks the primary group (gidNumber). If I modify my Ldap user like this, getent passwd : *m.ambrosy:x:2000:2003:m.ambrosy:/home/m.ambrosy:/bin/bash *It works fine but my "l_mail" group must be secondary (like an option for some users), not the primary gidNumber. Can I do it in the conf file?* * Am I making myself clear? Regards, Matthieu.

[Dovecot] Improving lmtp performance
by Joseba Torre 04 Feb '11

04 Feb '11

Hi, yesterday I migrated and old version with sendmail + courier to a virtual machine (vmware) with postfix and dovecot 2.0.9. Everything worked fine, but with a more or less default setup for both dovecot and postfix, lmtp performance was pretty bad: a message was written to an inbox every 2 or 3 seconds. With that rate and a 5000+ and growing mail queue mail delivery was really slow. After searching both the wiki and this list I didn't find anything related to this. I tried a couple of things, and finally added process_min_avail = 10 to service lmtp entry in 10-master.conf and local_destination_concurrency_limit = 10 in postfix's main.cf Now mail delivery is really fast, and my mail queue was delivered in a very sort time. Is this the right solution, or there's a better setup to improve mail delivery performance? Also, if this is a common problem, may be something should appear in http://wiki2.dovecot.org/LMTP Thanks. -- Joseba Torre. Vicegerencia de TICs, área de Explotación

[Dovecot] disabling outgoing mail ?

[Dovecot] Quota ignore issue
by Tim Traver 03 Feb '11

03 Feb '11

Hi Timo, ok, in my dovecot setup, I have a setting to ignore messages in the Spam folder (I will put my dovecot -n at the end of the message), and a strange thing appears to be happening. If I do a quota recalc on an account, It creates the maildirsize file correctly, without the contents of the Spam folder calculated into the total used. But, it looks like when a new spam email is delivered, before the sieve rules in the lda can move it into the spam folder, it is added to the maildirsize file. Then, once it is moved into the Spam folder, if it is directly expunged from the folder, it isn't subtracted from maildirsize file. I am using roundcube as a webmail solution, and it recognizes the Spam folder and lets users directly empty the Spam folder instead of moving it to the trash, and then removing it. If I do move the mail from the Spam folder to the Trash folder, and then empty the trash, it then puts the subtraction in the maildirsize folder. So, either it shouldn't add it in the first place, or even though it is deleted directly from the Spam folder, it should be subtracted from the maildirsize folder, right? Hmmm...maybe its the structure of the default sieve command that I have that is making it want to add it? here is the default sieve script that I use in the sieve_after field : require "fileinto"; # rule:[Spam and Virus Tag] if anyof (header :contains "Subject" "[VIRUS-TAG]", header :contains "Subject" "[SPAM-TAG]") { fileinto "Spam"; stop; } Essentially, what is happening is that users are getting their quota filled up for messages that were in their Spam folder...

[Dovecot] Reproducable hang caused by IMAP server
by Matthias Scheler 03 Feb '11

03 Feb '11

Hello, I have problems with Dovecot 2.0.9 (and 2.0.8) under NetBSD/amd64 5.1. "mutt" hangs when I try to quit it after accessing a folder via IMAP. I can reproduce the problem with these steps: 1.) I run "mutt -f =foo" to access folder "foo" via IMAP. The folder contains about 10 messages in my case. 2.) I tag two of the messages and then save them to a *non existent* folder. When "mutt" asks whether the folder should be created I confirm the action. 3.) Finally I exit "mutt" and confirm the question whether the messages marked as deleted (by the save in step 2) should be deleted. 4.) "mutt" now hangs indefinitely. I've attached a packet capture of the above steps to this e-mail. As far as I can tell from the packet capture and debugging "mutt" with "gdb" it waits for the IMAP server to confirm the logout which never happens. I've never seen this problem with Dovecot 1.2.16. Here is the requested debugging information: Output of "dovecot --version": 2.0.9 Output of "doveconf -n": # 2.0.9: /etc/pkg/dovecot/dovecot.conf # OS: NetBSD 5.1_STABLE amd64 auth_mechanisms = cram-md5 digest-md5 plain login listen = *, [::] mail_debug = yes mail_location = mbox:~/Mail:INBOX=/var/mail/%u passdb { args = /etc/pkg/dovecot/passwd driver = passwd-file } pop3_uidl_format = %08Xv%08Xu protocols = imap pop3 service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } ssl_cert = </etc/openssl/certs/dovecot.pem ssl_key = </etc/openssl/private/dovecot.pem userdb { driver = passwd } Kind regards -- Matthias Scheler http://zhadum.org.uk/

In the config file I have protocol imap { mail_plugins = quota imap_quota trash expire autocreate } Using the following password/user queries: password_query = SELECT username as user, password, if('%d'='virttest2.xxx.net', 'acl imap_acl',null) as mail_plugins, concat('/var/vmail/%d/', maildir) as userdb_home, concat('maildir:/var/vmail/%d/', maildir) as userdb_mail, 101 as userdb_uid, 502 as userdb_gid, CONCAT('*:bytes=', CAST(quota AS CHAR)) AS quota_rule FROM mailbox WHERE username = '%u' user_query = SELECT maildir, if('%d'='virttest2.xxx.net', 'acl imap_acl',null) as mail_plugins, 101 AS uid, 502 AS gid, CONCAT('*:bytes=', CAST(quota AS CHAR)) AS quota_rule FROM mailbox WHERE username = '%u' AND active = '1' Now in n the log I do see the mail_plugins override but for some reason I get an IMAP error when trying to share folders. out: OK 1 user=user20(a)virttest2.xxx.net mail_plugins=acl imap_acl quota_rule=*:bytes=512000000 ERROR: IMAP server does not support the ACL capability, sorry.

[Dovecot] Logging on syslog and selected dovecot files at the sametime

Is it possible to send logs to syslog and files set by log_path and log_info_path on config?

[Dovecot] automated mailbox trimming?
by Monique Y. Mudama 02 Feb '11

02 Feb '11

Hello all, If this is answered in the wiki, I apologize. Please point me to it and I'll be on my way ... This may be more of a MailDir-generic question, except that as I understand it there's some wiggle room in the naming of the message files. I've just switched from an mbox-based mail system to Dovecot with MailDir. With mbox, I used logrotate to keep some of my mailboxes (spam, sent, stuff like that) down to only the most recent messages. What's the best way to go about mailbox trimming with dovecot's implementation of maildir? I was thinking of writing a script to simply move or delete old files, but would I mess up dovecot's expectations for directory/file structure that way? My mail directories are in my user's home directory. I'm fine with writing a script or application (time permitting, of course), but before I do so, is there already a solution out there? In case it's relevant: $ dovecot --version 1.2.15 $ dovecot -n # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.37 x86_64 Debian 6.0 log_timestamp: %Y-%m-%d %H:%M:%S ssl: required login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_privileged_group: mail mbox_write_locks: fcntl dotlock auth default: passdb: driver: passwd-file args: /etc/dovecot/passwords userdb: driver: passwd userdb: driver: passwd-file args: /etc/dovecot/passwords

[Dovecot] Cannot authenticate with new Red Hat/Fedora SHA512
by John Cooper 01 Feb '11

01 Feb '11

RHEL6 and Fedora 14 use an improved password algorithm of SHA512 on a brand new install of the OS (:$6$ in shadow file). cat /etc/shadow user1:$6$<salt>$<password>:15006:0:99999:7::: I cannot get dovecot to authenticate. I've search for a way to change the default algorithm in dovecot and found you should use CRYPT but I don't know what to put in the /etc/dovecot/dovecot.conf or /etc/dovecot/conf.d/* Can this be done or do you need to use an alternate password file with MD5? Thanks, John.

[Dovecot] cgroup support
by Andreas Pelme 01 Feb '11

01 Feb '11

Hi, I am setting up a system that enforces cgroup restrictions when a user logs in via SSH, and for all the services that are run by a particular user. I am also running dovecot to give users IMAP/POP access to their mailboxes. However, to be part of a cgroup, PIDs must be explicitly added to the cgroup tasks file. So for now, all my processes are run with resource restrictions, except for Dovecot processes. It would be really cool if dovecots child/worker processes could be added the a cgroup in addition to the usual setuid/chroot protections that already exists. Adding a process to a cgroup is a matter of writing the PID to the correct cgroup tasks file. If this were implemented as an extra field in userdb, it could be very powerful, and allow for all kinds of resource management/accounting of dovecot processes. This would obviously not be cross-platform, since cgroups are a feature of the Linux kernel. Would that be a problem? Is support for cgroups something that could be considered for dovecot at all? Are there other ways to put dovecot processes in cgroups? I do not really have a patch or a plan for how everything would work out in detail. If this would be useful for dovecot, I would be happy to start hacking on a patch. Cheers Andreas

[Dovecot] Permissions issues after dovecot reload
by Matt Rude 01 Feb '11

01 Feb '11

Hello, Today while looking at a different issue (one user couldn't retrieve mail; DNS issue) I set 'mail_debug=yes' then ran `dovecot reload` on our mail server. After running the reload, dovecot started complaning about permission issues with the dict file, and preceded to try to kill it's self. The self reload didn't seem to work, and since this is a production system, I was forced to restart the dovecot service. After the restart of the service, everything seemed to go back to normal. Dovecot is currently working as expected, no other permission errors in the logs. Dovecot Version: 2.0.9 (3582271a897e) running on Fedora 14 running with a mySQL setup including dict tables (quota, expire). The virtual user's mail has a local user and group id of 1000.

[Dovecot] disable_plaintext_auth = no ignored by dovecot in Ubuntu 10.04
by David Mattox 31 Jan '11

31 Jan '11

Help!! I have been trying to get Dovecot configured to allow plaintext auth with no success. After some testing with the mail system I discovered the >dovecot -a commant to dump the config file values from the program. Gee, changing the value of disable_plaintext_auth had no effect on what the program reported this value to be! To eliminate possible errors caused by other config file entries I finally restored the /etc/dovecot/dovecot.conf file that was created by installing the package. I then changed the one line to uncomment disable_plaintext_auth and set it equal to no. restart the box and execute dovecot -a The value is still set to the default value of yes... Help! What is happening and how to I get this system to allow plain text auth without TLS? I did also try setting different ports for imap, imaps, pop3, pop3s inside the seperate protocol blocks with no effect. Below you will find a partial of the config file. Below that you will find the output of >dovecot -a and >dovecot -n Thank you in advance for any help with this problem.

[Dovecot] Particular user post-login hang
by Henry C. 31 Jan '11

31 Jan '11

Greets, I'm using dovecot 2.0.9 (also tried rolling back to 2.0.8 which does the same - the output below is from 2.0.8), and this problem is imap specific. The following is a recurring problem with a specific user - as far as we can tell, other users are working just fine (there are thousands); but I bet there are others. In a nutshell: User authenticates OK, then the imap process hangs. It's almost as if something in the user's inbox is causing the problem, since if I clear all emails (and cache), then things work fine. The user will then receive emails OK for some random period (maybe a few days) and be able to read/write OK via imap, and the problem will re-occur.

[Dovecot] dovecot can't see mail that is there
by Joachim Ferreira 31 Jan '11

31 Jan '11

Hi list, I've yet to figure out what's the issue with my installation, why I can't see the mails that are definitely there. I've updated with last package: dovecot-2.0.9-1.fc14.x86_64.rpm and performed the following test: 1) send a simple 2 lines test mail from "root" to user "testdvct" with alpine 2) login under "testdvct" + run alpine + list (only list, not read) the mail: +------------------------------ Alpine Output --------------------------------------+ | ALPINE 2.02(1266) MESSAGE INDEX Folder: INBOX Message 1 of 1 NEW | | | | + N 1 17:43 root (881) | +--------------------------------------------------------------------------- --------+ so it tells me I've got one mail from root 3) I issue the command: "strace -o strace-dovecot.txt -p 2218" where 2218 is the /usr/sbin/dovecot PID 4) telnet into pop3: # telnet localhost pop3 Trying 127.0.0.1...

[Dovecot] Duplicate messages when moving message to inbox
by Ron Garret 31 Jan '11

31 Jan '11

Hello, I am encountering a strange problem but I'm not sure if it's a dovecot problem or a Mac Mail problem. The symptom is that if I move a message from a folder into my inbox the message ends up showing up as a duplicate in Mac Mail. On the server it's still just one message. This ONLY happens when I move a message IN to the inbox. It does not happen when I move a message out of my inbox into a folder, or when I move a message between folders. I can force a sync on Mac Mail and the duplicate is still there. If however I quit Mac Mail and start it up again, the duplicate disappears. I can move one of the duplicated messages out of my inbox into a folder and then back into my inbox repeatedly and end up with (apparently) an arbitrary number of copies of the same message. On the server, though, there is still only one file. Surely I'm not the first person to have encountered this behavior? Does anyone happen to know if this is a dovecot bug or a Mac Mail bug (or, hopefully, a configuration problem)? Thanks, rg

It's a theoretical problem mostly, especially in your case. It's mainly visible when doing stress testing with large maildirs. I doubt in regular use it matters. Courier doesn't try to prevent it in any way and it seems to have worked mostly ok. > Or is the UID supposed to change when the flags change? No.

[Dovecot] dovecot: pop3-login: Disconnected (tried to use disabled plaintext auth): method=PLAIN
by John Espiro 30 Jan '11

First, my problem. Settings are below that... Everything works fine - I can login to webmail (users are tied to LDAP). I can send and receive email via my Thunderbird Client. However in my mail.err log I see lots of messages that say: dovecot: pop3-login: Disconnected (tried to use disabled plaintext auth): method=PLAIN 1.) What does that mean, and how can I solve it? 2.) With regards to pop3s I am not altogether sure that I am using the right config in my dovecot.conf file (also below). Can someone let me know?

The error only disappears when I set the global mail_uid and mail_gid but that's not what I need. I need to be able to use a specific uid/gid/home for each account. Weird. Regards, Eric

[Dovecot] inform users's about new spam
by ckubu 30 Jan '11

30 Jan '11

Hallo evryone! Mailsetup: postfix+dovecot2 with postgres database backend - about 2,000 virtual mailboxes, growing.. New possible spam will be sorted into a users directory named "spam", emails older than 30 day's in that folder will be deleted by using expunge. I would like to inform my users evry two day's (or something like that) about new emails in the spam folder. Can you give me a hint how to handle that ? Are there helpful tools , or have i to wrote my own script, walking through the folders, checking for new emails since last check and finally inform the user if needed. Best wishes Christoph

[Dovecot] Copying sieve scripts
by Christoph Pleger 30 Jan '11

30 Jan '11

Hello, I am using squirrelmail with avelsieve to edit my filter rules. The filter rules are like this: 1. If the message contains a virus, delete the mail and notify me by email. 2. If the message is spam, deliver it to my spam folder. 3. If the message is from the dovecot mailing list, deliver it to my dovecot folder Yesterday, I created a new user and wanted to let him have rules 1 and 2 like above, only with another destination for email notification. So, I copied my sieve script into the sieve directory of the new user, deleted rule 3, changed the destination for email notification and then called sievec to compile the rule set. But this did not work like expected: Using squirrelmail, I saw that the new user had only rules 1 and 2, but the destination in rule 1 still contains my email address. My own account still has three rules. So, this simple way of copying sieve scripts does not work. Is there another way to copy sieve rules from one user to another? Regards Christoph

[Dovecot] sql : uid, gid, home ignored ?
by Eric Diaz Fernandez 30 Jan '11

30 Jan '11

Hello, I'm trying to setup a dovecot imap server. version is 2.0.9 I've setup a mysql database using: user_query = \ SELECT home, uid, gid, home as userdb_home, uid as userdb_uid, gid as userdb_gid, \ FROM user WHERE username = '%n' AND domain = '%d' AND active = 'Y' password_query = \ SELECT username AS user, password, home as userdb_home, uid as userdb_uid, gid as userdb_gid, home, uid, gid \ FROM user WHERE username = '%n' AND domain = '%d' AND active ='Y' (I get the information with and without the userdb_ prefix since I was not sure what was needed) When I login, I see the password_query in the debug log and it says: client out: OK 1 user=theuser home=/home/theuser uid=1000 gid=1000 master in: REQUEST 547880961 10068 1 e6...(hexadecimal stuff) master out: USER 547880961 theuser But in the mail.err log i see: dovecot: imap(theuser): Error: user theuser: Couldn't drop privileges: User is missing UID (see mail_uid setting) dovecot: imap(theuser): Error: Internal error occurred. Refer to server log for more information. The same two lines are also displayed in mail.info and mail.log Further testing (setting mail_uid & mail_gid to a nobody) shown that the home setting was ignored too. The sql example says that uid and gid are supposed to be an override of the mail_uid and mail_gid settings. Any idea of why the columns are ignored ? Thanks in advance, Eric
