[Dovecot] migration 1.1.7 to 2.0.6
by Brian D 28 Oct '10

28 Oct '10

I'm thinking of migrating from 1.1.7 (default RPM on SUSE 11.1) to 2.0.6 compiled from source using the default locations. Any Gotchas to expect that are different to an upgrade from 1.2? Any hints from moving from RPM to compiling from source and retaining the default configuration under /usr/local?

[Dovecot] Can quota_rule be inherited by child mailboxes?
by ian+dovecot＠comtek.co.uk 28 Oct '10

28 Oct '10

Is there a way to make quota_rule apply to subfolders? I've got some symlinked mailboxes which I want to exclude from quotas. This would work, but is verbose: quota_rule6 = USERS.aaa:ignore quota_rule7 = USERS.bbb:ignore ... quota_rule9999 = USERS.zzz:ignore But simply writing this: quota_rule7 = USERS:ignore doesn't apply to USERS.xxx and so on. The wiki says '*' isn't supported as a wildcard and frankly I'm struggling with the source code!

[Dovecot] Convert Plugin
by Dr Matthew Williams 28 Oct '10

28 Oct '10

Hello, I have been investigating mailbox conversions and have used the convert plugin under Dovecot V1.x. I cannot find the plugin in the list on the wiki for Dovcot V2.x, is it not included for a reason? I understand that I can do a post-login script to do the conversion, any guidance on best practices?

[Dovecot] Per User Quotas with LDAP on Dovecot 1.x
by Camron W. Fox 28 Oct '10

28 Oct '10

Alle, We're running Dovecot V1.0.7 on RHEL5.5, using maildir. We would like to user per user quotas with an OpenLDAP (V2.3.43) backend. We have setup a default quota in /etc/dovecot.conf: quota = maildir:storage=10240:ignore=Trash And have the following userdb configs in /etc/doveconf.conf: userdb ldap { args = /etc/dovecot-ldap.conf } and the following user_attrs defined in /etc/dovecot-ldap.conf user_attrs = uidNumber=uid,gidNumber=gid,mailQuotaSize=quota=maildir:ignore=Trash:storage,mail_plugins The user's quota setting is: dn: uid=loadtest,ou=people,dc=subaru,dc=nao,dc=ac,dc=jp mailQuotaSize: 1024000 Dovecot-imap appear to recognize the quota from ldap, as the Thunderbird quota plugin reads the correct info from LDAP if the mailQuotaSize entry exists, and the default storage=10240 from doveconf.conf if there is no LDAP attr. However, deliver bounces the mails with a quota exceeded message: deliver(loadtest): Sep 28 10:46:23 Info: msgid=<20100928204620.B83876402EA(a)loa.subaru.nao.ac.jp> : save failed to INBOX: Quota exceeded deliver(loadtest): Sep 28 10:46:23 Info: msgid=<20100928204620.B83876402EA(a)loa.subaru.nao.ac.jp> : Rejected: Quota exceeded Are we misunderstanding the way quotas are supposed to work in 1.x, or are we just missing something, period? Any help would be appreciated. Best Regards, Camron -- Camron W. Fox Hilo Office High Performance Computing Group Fujitsu Management Services of America, Inc. E-mail: cwfox(a)us.fujitsu.com

[Dovecot] imap can't reconnect to auth-master after setuid
by Mike Abbott 27 Oct '10

27 Oct '10

With service imap { client_limit = 5, service_count = 0 }, when the auth process crashes the existing imap processes cannot reconnect to the auth-master socket because they have long ago dropped root privileges. Is the right solution to this: (1) change the perms on the auth-master socket so processes running as vmail:vmail can connect to it, or (2) change the code so that multi-client imap processes stop accepting new clients when they notice an auth bounce? If (1), the wiki should be updated to mention this. Thanks.

[Dovecot] auth crash in 2.0.3
by Mike Abbott 27 Oct '10

27 Oct '10

Here's another one-off crash in dovecot-2.0.3's auth process. Looks like request->mech == NULL in auth_request_initial(). I don't see any obvious fixes to this code between 2.0.3 and 2.0.6 so it may still be present in 2.0.6. Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0x0000000000000018 0 auth 0x000000010d89381b auth_request_initial + 85 1 auth 0x000000010d891844 auth_penalty_anvil_callback + 207 2 libdovecot.0.dylib 0x000000010d8ea44f anvil_client_connect + 364 3 libdovecot.0.dylib 0x000000010d8f77e9 io_loop_handler_run + 234 4 libdovecot.0.dylib 0x000000010d8f82bb io_loop_run + 56 5 libdovecot.0.dylib 0x000000010d8edf98 master_service_run + 27 6 auth 0x000000010d89b18a main + 674 7 auth 0x000000010d88ec14 start + 52 There were several "Timeout waiting for handshake from auth server" errors from imap-login and pop3-login in the minutes before this crash.

Does anyone have clients using blackberrys to access their emails on a dovecot server? If so are there any gotcha's that I need to configure in dovecot for this to work? Looks like all emails go to and from a blackberry server before getting to clients. thanks, ddh -- Dwayne Hottinger Network Administrator Harrisonburg City Public Schools "Everything should be made as simple as possible, but not simpler." -- Albert Einstein "The hottest places in Hell are reserved for those who, in times of moral crisis, preserved their neutrality." -- Dante

[Dovecot] Corrupted transaction log file
by Andre Nathan 27 Oct '10

27 Oct '10

Hello I run dovecot 2.0.6 on a two-machine cluster using OCFS2 as the file system. I have some error messages like these in my log: Oct 25 01:07:50 box5 dovecot: lmtp(8886, suporte=100br.com(a)lmtp1.prv.f1.k8.com.br) Error: Corrupted transaction log file /var/lib/imap/user/a3/suporte=100br.com/stor age/dovecot.map.index.log seq 29: Transaction log corrupted unexpectedly at 21536: Invalid size 0 (type=0) (sync_offset=21908) Oct 25 01:07:50 box5 dovecot: lmtp(8886, suporte=100br.com(a)lmtp1.prv.f1.k8.com.br) Error: Index /var/lib/imap/user/a3/suporte=100br.com/storage/dovecot.map.index: Lost log for seq=29 offset=21796 Oct 25 01:07:55 box5 dovecot: lmtp(8885, suporte=100br.com(a)lmtp1.prv.f1.k8.com.br) Error: Log synchronization error at seq=30,offset=312 for /var/lib/imap/user/a3/su porte=100br.com/storage/dovecot.map.index: Append with UID 5404, but next_uid = 5405 Oct 25 02:37:53 box5 dovecot: lmtp(8885, suporte=hostnet.com.br(a)lmtp1.prv.f1.k8.com.br) Error: Log synchronization error at seq=47,offset=22944 for /var/lib/imap/user/03/suporte=hostnet.com.br/storage/dovecot.map.index: Extension record update for invalid uid=21815 These two accounts happen to be accessed simultaneously by a number of people, but there are similar errors for "normal" accounts too, just not the same amount of logs. Is it not considered safe to do this kind of simultaneous access in a distributed filesystem like OCFS2? Is there a way to fix this error? Would a "doveadm force-resync" do it? Thanks, Andre
