[Dovecot] dovecot 2.1.15 hangs while connecting.
by Albert Whale 28 May '14

28 May '14

I am using Dovecot in two Server environments. My Legacy (5 years+ old) servers are running dovecot 1.1.20, and are responding as expected. These servers are using an NFS based storage for the /home directory structure, and are working beautifully. However, I need to replace these inefficient servers, and get more current. That brings me to the problem, where I am implementing Dovecot 2.1.15, which does not complete the authentication cycle. I have converted the 1.1.20 configuration using the documentation available, and I have the following for my running configuration (which is not working): # 2.1.15: /etc/dovecot/dovecot.conf # OS: Linux 3.8.13.4-server-1.mga3 i686 Mageia 3 auth_debug = yes base_dir = /var/run/dovecot/ disable_plaintext_auth = no lock_method = dotlock login_greeting = SpamZapper Email ready. login_log_format_elements = user=<%u> method=%m rip=%r lip=%l %c mail_debug = yes mail_fsync = always mail_location = maildir:~/Maildir mail_nfs_index = yes mail_nfs_storage = yes mail_privileged_group = mail mmap_disable = yes passdb { driver = pam } protocols = imap pop3 service auth { user = root } service imap-login { chroot = login client_limit = 256 user = dovecot } service pop3-login { chroot = login client_limit = 256 user = dovecot } ssl = no userdb { driver = passwd } verbose_proctitle = yes protocol pop3 { mail_max_userip_connections = 50 pop3_logout_format = top=%t/%p, retr=%r/%b, del=%d/%m, size=%s pop3_uidl_format = %08Xv%08Xu } protocol lda { postmaster_address = postmaster(a)example.com } I have captured the Debug output of the dovecot process while attempting to connect: May 27 13:02:10 ns dovecot: auth: Debug: client in: AUTH#0111#011PLAIN#011service=pop3#011session=IzAYqGT6pgBCz4Xk#011lip=66.207.133.227#011rip=66.207.133.228#011lport=110#011rport=38566#011resp=<hidden> May 27 13:02:10 ns dovecot: auth-worker(551): Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth May 27 13:02:10 ns dovecot: auth-worker(551): Debug: Module loaded: /usr/lib/dovecot/modules/auth/libdriver_mysql.so May 27 13:02:10 ns dovecot: auth-worker(551): Debug: pam(aewhale,66.207.133.228): lookup service=dovecot May 27 13:02:10 ns dovecot: auth-worker(551): Debug: pam(aewhale,66.207.133.228): #1/1 style=1 msg=Password: May 27 13:02:10 ns dovecot: auth: Debug: client passdb out: OK#0111#011user=aewhale May 27 13:02:10 ns dovecot: auth: Debug: master in: REQUEST#0112671116289#011453#0111#01174d85bf0d878139a83e682a869786da9 May 27 13:02:10 ns dovecot: auth-worker(551): Debug: passwd(aewhale,66.207.133.228): lookup May 27 13:02:10 ns dovecot: auth: Debug: master userdb out: USER#0112671116289#011aewhale#011system_groups_user=aewhale#011uid=501#011gid=501#011home=/home/aewhale May 27 13:02:10 ns dovecot: pop3-login: Login: user=<aewhale>, method=PLAIN, rip=66.207.133.228, lip=66.207.133.227 May 27 13:02:10 ns dovecot: pop3(aewhale): Debug: Effective uid=501, gid=501, home=/home/aewhale May 27 13:02:10 ns dovecot: pop3(aewhale): Debug: maildir++: root=/home/aewhale/Maildir, index=, control=, inbox=/home/aewhale/Maildir, alt= All processing stops here.

[Dovecot] Corrupted Mail?
by Arthur Dent 28 May '14

28 May '14

Hello All, I have a Dovecot v2.2.12 installation running on a Fedora 20 box which is the mailserver for my family. This means that it is serving only 4 accounts. I use fetchmail->procmail to feed Dovecot and I read my mail on clients such as Evolution on (another) Fedora 20 machine, iPad/iPhone or squirrelmail on the web (running on the same Fedora 20 server). The average mail throughput for the whole family is around a couple of hundred messages per day, but each (and every) day I get between 3 and 10 of the following messages: dovecot: imap(mark): Error: Next message unexpectedly corrupted in mbox file /home/mark/mail/MLists/Fail2Ban at 3407473: 1 Time(s) I have googled, but with little success. What I have found seemed to suggest that removing the .index files and allowing Dovecot to rebuild them will solve this. I did: find /home -type f -name "dovecot.index.*" -exec rm -f {} \; but it has made no difference. Can anyone help me solve this please? Thanks in advance Mark

[Dovecot] dsync changing source permission to "root" in backup mode
by Peter Mogensen 27 May '14

27 May '14

Hi, We have dsync failing once in a while when running in "backup" mode. What's strange is that the result is that the file permissions on the *source* machine ends up with the wrong permissions (set to uid 0). Even though the dsync manual clearly says: "Backup mails from default mail location to location2 (or vice versa, if -R parameter is given). No changes are ever done to the source location. Any changes done in destination are discarded." Running: 'dsync -R -o mail_home=/users/maildir backup ssh -c arcfour src-host "dsync -o mail_home=/users/maildir"' I know it's running as root, but even then ... it shouldn't modify the source in "backup" mode ?? The error message from dsync when failing is: dsync-remote(root): Error: Cached message size larger than expected (5292 > 5289) dsync-remote(root): Error: Maildir filename has wrong S value, renamed the file from /users/maildir/.Sent/cur/1381224782.M959810P3574.mail,S=5292,W=5411:2,S to /users/maildir/.Sent/cur/1381224782.M959810P3574.mail,S=5289:2,S dsync-remote(root): Error: Corrupted index cache file /users/maildir/.Sent/dovecot.index.cache: Broken physical size for mail UID 1040 dsync-remote(root): Error: dsync(dst-host): read(/users/maildir/.Sent/cur/1381224782.M959810P3574.mail,S=5292,W=5411:2,S) failed: Cached message size larger than expected (5292 > 5289) /Peter

[Dovecot] Segfault when deselecting virtual folder 2.2.13+ HG TIP
by Colin Knox 27 May '14

27 May '14

Hello, I'm seeing a segfault in the imap process with the current mercurial tip (including changeset 17382 e99cd21e1f92) when selecting a particular virtual mail folder (but no other virtual mailboxes) and then selecting a different mail folder as in the IMAP transcript below. The same segfaults are triggered with IMAP clients. The situation is worse with the 2.2.13 which segfaults when any virtual mailbox is deselected so the recent patch helps partially. Configuration summary, IMAP session in gbd including backtrace and virtual mailbox spec follow. Any ideas what's causing this?

[Dovecot] Odd ownership of the dovecot-uidlist file
by dclist.hook＠hook.net.nz 27 May '14

27 May '14

Hi, We have just recently switched from Courier to Dovecot for both IMAAP and POP access for our shared hosting platform, and while the issues we have been seeing with Courier have gone away a new one has popped up. Unfortunately googling for an answer is difficult as it falls into the ownership and permissions category which people seem to have all the time. But in those cases it always happens, whereas what we are seeing is a random ownership change on the dovecot-uidlist file. Basically what we see is the user is able to login fine for days and then all of a sudden the file has changed ownership to a user under a different domain, what's worse is the other user has not even logged in during that time. Here's a snippet from a case from a month ago which was escalated to us, there are plenty of other examples but its so random we only know its happened when the customer complains or we happen to watch the logs, the current help desk procedure when the customer calls is to just fix the ownership of the file. -- 8<-- Mar 25 11:18:05 brio dovecot: pop3-login: Login: user=<accounts@DOMAIN1>, method=PLAIN, rip=IP, lip=IP, mpid=21739, TLS, session=<mwQLnGH1ZAB2XalI> Mar 25 11:18:08 brio dovecot: pop3(accounts@DOMAIN1): Disconnected: Logged out top=0 (0 b), retr=4 (274142 b), messages=27 (10797760 b), del=0 Mar 25 11:19:24 brio dovecot: pop3(accounts@DOMAIN1): Error: open(/mnt/spool/keepers/t/DOMAIN1/accounts/Maildir/dovecot-uidlist) failed: Permission denied Mar 25 11:19:24 brio dovecot: pop3(accounts@DOAMIN1): Error: open(/mnt/spool/keepers/t/DOMAIN1/accounts/Maildir/dovecot-uidlist) failed: Permission denied -- 8<-- In this case the ownership of the file was: -rw------- 1 jacqui-30747 DOMAIN2 48839 Mar 25 10:31 dovecot-uidlist when it should be: -rw------- 1 accounts-25105 DOMAIN1 48839 Mar 25 10:32 dovecot-uidlist As you can see both the user and the group have changed to a different user as if that user had recreated the file. Its worth noting that the parent directory does not change: drwx------ 8 accounts-25105 DOMAIN1 4096 Mar 25 10:31 . so this user should not even be able to access this file. It would be great if someone can give us some hints where the problem maybe as this has us stumped. Some more detail if it helps: root@brio:~# dovecot -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.2 auth_mechanisms = plain login cram-md5 apop auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@& default_process_limit = 3000 disable_plaintext_auth = no lock_method = dotlock mail_fsync = always mail_location = maildir:~/Maildir:INDEX=/home/indexes/%1d/%n@%d mail_nfs_index = yes mail_nfs_storage = yes mail_plugins = " quota" maildir_stat_dirs = yes mmap_disable = yes namespace inbox { inbox = yes 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 = INBOX. separator = . subscriptions = yes } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } passdb { args = /etc/dovecot/dovecot-sql-cram.conf.ext driver = sql } plugin { quota = maildir:User quota } protocols = " imap pop3" service imap-login { inet_listener imap25 { port = 25143 } } service imap-postlogin { executable = script-login -d /usr/local/bin/postlogin.sh } service imap { executable = imap imap-postlogin } service pop3-login { inet_listener pop325 { port = 25110 } } service pop3 { executable = pop3 imap-postlogin } ssl_cert = </var/www/mailadmin/ssl/cert.pem ssl_crypto_device = dynamic ssl_key = </var/www/mailadmin/ssl/mailx.hosts.net.nz.key userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } userdb { args = /etc/dovecot/dovecot-sql-cram.conf.ext driver = sql } verbose_proctitle = yes protocol imap { imap_capability = +XHOST_brio imap_logout_format = bytes=%i/%o mail_max_userip_connections = 50 mail_plugins = " quota imap_quota" } protocol pop3 { mail_max_userip_connections = 10 pop3_lock_session = no pop3_logout_format = top=%t (%p b), retr=%r (%b b), messages=%m (%s b), del=%d pop3_save_uidl = yes pop3_uidl_format = %f } root@brio:~# dpkg -l|grep dovecot ii dovecot-core 1:2.1.7-7 amd64 secure mail server that supports mbox, maildir, dbox and mdbox mailboxes ii dovecot-imapd 1:2.1.7-7 amd64 secure IMAP server that supports mbox, maildir, dbox and mdbox mailboxes ii dovecot-mysql 1:2.1.7-7 amd64 MySQL support for Dovecot ii dovecot-pop3d 1:2.1.7-7 amd64 secure POP3 server that supports mbox, maildir, dbox and mdbox mailboxes Mailbox storage is done over various NFS stores, however each user has a specific NFS store Connections are load balanced using LVS and keepalived over approx 10 real servers, persistant connections are setup so that a single user should only hit a single dovecot server (this is different from our courier setup due to the known NFS limitations with dovecot) We also have IMAP indexes stored on the dovecot servers ext3 file system itself rather than NFS. Each server is setup and maintained by puppet, and any one of the servers may see the issue. All servers are x86 with at least 2Gb of RAM User information comes from a MySQL database, and testing the SQL statements only ever return the correct record. Exim is writing to the Maildir with the correct permissions, and after fixing the ownership of the file dovecot can read and change the mailboxes. We do have a postlogin.sh script which runs after authentication to convert the old courier files over to the dovecot ones, this only happens however when the process has not run before (it appears dovecot deletes the files and recreates them, so we use a state file). Adding debugging to the script shows its running as the correct user at the last successful login. It does not run at all after the ownership has changed. There are some users who this is happening regularly, and other users who it has happened to only once. It is also not just limited to POP3, although this is where we commonly see it as dovecot accepts the IMAP connection if the ownership on a sub folders uidlist is different. If you need any further detail, I can provide it. Debugging could be much more difficult because of how random it is, while it can happen daily there have been periods of up to one week before its seen. Any help in finding this would be greatly appreciated, Cheers, Bruce

[Dovecot] Incorrect IMAP search results when FTS/Squat indexes are present with 2.1.7
by Robert L Mathews 27 May '14

27 May '14

We recently upgraded from Dovecot 1.2.15 (on Debian squeeze) to Dovecot 2.1.7 (on Debian wheezy/stable). For now, we continue to use FTS with Squat indexes. We'd like to eventually switch to Lucene but it's not yet supported in Debian stable. Since upgrading to 2.1.7, we've seen some problems with IMAP search results when an FTS Squat index is present (i.e., when the "dovecot.index.search" and "dovecot.index.search.uids" files are present). If it's present, even header searches sometimes give incorrect results (such as searches on FROM or SUBJECT headers). I'm wondering if this is a known issue with 2.1.7 and whether upgrading to a later version of Dovecot with Squat is likely to fix this (due to, say, <http://www.dovecot.org/list/dovecot-cvs/2012-June/020881.html>), or if Squat in all versions is a lost cause and I need to switch to Lucene. I can demonstrate the problem by showing the results of three searches on my mailbox. First, here are the correct results for header FTS searches when no "dovecot.index.search[.uids]" file is present: ---- .

[Dovecot] LDAP: allow pop3, restrict imap
by Andreas Schulze 26 May '14

26 May '14

Hello, I have all userdata in a ldapserver. Every user has the right to use pop3. There is no explicit attribute allowing that. It's simply possible. Now I like to add imap. For a starting period I like to restrict, who may use imap. http://wiki2.dovecot.org/Authentication/RestrictAccess mention a solution where I could modify ldap pass_filter. But that require an attribute "service=pop3" to be present in the ldap servers. In my case I have to add it for every existing user :-/ No way... Are there other options? Thanks, Andreas

[Dovecot] socket /var/spool/postfix/private/auth not created
by lister171254 26 May '14

26 May '14

I'm on Ubuntu 13.10 and followed these instructions http://wiki2.dovecot.org/HowTo/PostfixAndDovecotSASL to configure Dovecot for Postfix. No matter what I try, the listener is not created. <http://dovecot.2317879.n4.nabble.com/file/n48182/32.png> dovecot -n does not show the listener (I guess that's why its not created) This is the extract from the /etc/dovecot/conf.d/10-master.conf --------------- service auth { # auth_socket_path points to this userdb socket by default. It's typically # used by dovecot-lda, doveadm, possibly imap process, etc. Users that have # full permissions to this socket are able to get a list of all usernames and # get the results of everyone's userdb lookups. # # The default 0666 mode allows anyone to connect to the socket, but the # userdb lookups will succeed only if the userdb returns an "uid" field that # matches the caller process's UID. Also if caller's uid or gid matches the # socket's uid or gid the lookup succeeds. Anything else causes a failure. # # To give the caller full permissions to lookup all users, set the mode to # something else than 0666 and Dovecot lets the kernel enforce the # permissions (e.g. 0777 allows everyone full permissions). unix_listener auth-userdb { #mode = 0666 #user = #group = } # Postfix smtp-auth unix_listener /var/spool/postfix/private/auth { mode = 0600 user = postfix group = postfix } # Auth process is run as this user. #user = $default_internal_user } ---------------- Postfix is not involved in this right now as I expect the socket to be created when I restart dovecot. Can't find any meaningfull errors in the logs either. I hope I'm missing something obvious Thanks, Leo -- View this message in context: http://dovecot.2317879.n4.nabble.com/socket-var-spool-postfix-private-auth-… Sent from the Dovecot mailing list archive at Nabble.com.
