[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

[Dovecot] LMTP returncode 450?
by Peter Mogensen 30 Jun '11

30 Jun '11

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?

So this is a local disk with ext4 filesystem, nothing special? It shouldn't be breaking.. How often do these happen? Can you reproduce these by running imaptest against a test account? http://imapwiki.org/ImapTest

[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
by Mikko Lehto 30 Jun '11

30 Jun '11

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
