[Dovecot] what to expect from changing index location
by Davide Vaghetti 30 Jun '11

30 Jun '11

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello everybody, I have one thousand virtual users with mdbox mailbox format and 10 GByte quota. I have noticed some performance problem related to I/O (the mailbox disk is a 6TB raid1+0 on ISCSI), so I want to put the index files on a different disk. My actual mail_location is: mail_location = mdbox:/var/vmail/%-1.1u/%u/mdbox and I want to switch to mail_location = mdbox:/var/vmail/%-1.1u/%u/mdbox:INDEX=/var/indexes/%-1.1u/%u/ But I cannot figure out a pair of things: - - do the switch trigger the rebuilding of the index files? - - can I get rid of all the old index files? - - how much the index files (no fts squat) can grow? thanks in advance bye davide - -- Dott.

[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!
