Sieve permissions issue following update
by David Gessel 02 Feb '15

I recently updated dovecot and my sieve filters stopped working. Checking the logs I see: Dec 9 00:09:59 mailhost dovecot: lda(gessel(a)domain.com): Error: sieve: binary save: failed to create temporary file: open(/usr/local/etc/dovecot/sieve/10-move-spam.svbin.mailhost.domain.com.114.) failed: Permission denied (euid=5000(vmail) egid=5000(vmail) missing +w perm: /usr/local/etc/dovecot/sieve, we're not in group 6(mail), dir owned by 143:6 mode=0775) Dec 9 00:09:59 mailhost dovecot: lda(gessel(a)domain.com): Error: sieve: The LDA Sieve plugin does not have permission to save global Sieve script binaries; global Sieve scripts like `/usr/local/etc/dovecot/sieve/10-move-spam.sieve' need to be pre-compiled using the sievec tool However this fairly clear advice on the failure seems to be contradicted by: # id vmail uid=5000(vmail) gid=5000(vmail) groups=5000(vmail),6(mail) ? dovecot-pigeonhole-0.4.6 = up-to-date with index dovecot2-2.2.15_1 = up-to-date with index uname -a FreeBSD host.domain.com 9.3-RELEASE FreeBSD 9.3-RELEASE #0 r268932: Mon Jul 21 15:51:38 PDT 2014 gessel@host1.domain.com:/usr/obj/usr/src/sys/BARCELONA-13-08 amd64

Hello. I'm tried to use domain quota: plugin { quota = dict:Domain quota:%d:redis:host=127.0.0.1:prefix=domain/ quota_rule = *:storage=0 quota2 = dict:User quota::redis:host=127.0.0.1:prefix=user/ quota2_rule = *:storage=0 quota3_rule = Trash:storage=+5%% } but got next problem with it. Init state: # doveadm quota get -u "testacc(a)m.tld" Quota name Type Value Limit % Domain quota STORAGE 27070 204800 13 Domain quota MESSAGE 21 - 0 User quota STORAGE 27068 - 0 User quota MESSAGE 18 - 0 # doveadm quota get -u "testacc2(a)m.tld" Quota name Type Value Limit % Domain quota STORAGE 27070 204800 13 Domain quota MESSAGE 21 - 0 User quota STORAGE 2 - 0 User quota MESSAGE 3 - 0 Make recalc: # doveadm quota recalc -u "testacc2(a)m.tld" and got: # doveadm quota get -u "testacc2(a)m.tld" Quota name Type Value Limit % Domain quota STORAGE 2 204800 0 Domain quota MESSAGE 3 - 0 User quota STORAGE 2 - 0 User quota MESSAGE 3 - 0 # doveadm quota get -u "testacc(a)m.tld" Quota name Type Value Limit % Domain quota STORAGE 2 204800 0 Domain quota MESSAGE 3 - 0 User quota STORAGE 27068 - 0 User quota MESSAGE 18 - 0 All values of all domain quota are equals.

auth: Error: auth worker: Aborted request: Lookup timed out
by ML mail 01 Feb '15

01 Feb '15

Hello, I was checking the errors on my mailbox server using "doveadm log errors" and found that around 2-3 times a day I get the following error: Jan 29 22:14:43 auth: Error: auth worker: Aborted request: Lookup timed out Any ideas if this is a bad sign? For example some timeout on my side which is too low or is it just an aborted connection from the side of the IMAP client? The configuration on my Dovecot mailbox server can be found here: http://article.gmane.org/gmane.mail.imap.dovecot/80823 It is a Debian 7 box with standard debian packages. Best regards ML

[Bug ?] IMAP keywords are not preserved during mailbox conversion
by Alexander Moisseev 01 Feb '15

01 Feb '15

IMAP keywords (Thunderbird Tags) are not preserved during Maildir to mdbox conversion. For mailbox conversion I am using the command: # doveadm -o mail_location=maildir:~/Maildir sync -u user(a)example.com mdbox:~/mdbox After conversion all Thunderbird Tags are lost. Is it a bug or expected behavior? -- Alexander

LDAP Quota Limits & Warnings
by Leander Schäfer 30 Jan '15

30 Jan '15

I found this on the dovecot wiki: The following limit names are supported: * *storage*: Quota limit in kilobytes, 0 means unlimited. * *bytes*: Quota limit in bytes, 0 means unlimited. * *messages*: Quota limit in number of messages, 0 means unlimited. This probably isn't very useful. * *backend*: Quota backend-specific limit configuration. * *ignore*: Don't include the specified mailbox in quota at all. As I understood it, all 5 limit categories are valid to use with maildir format while only "storage" and "messages" are valid to use with dmbox format, right? Also the "ignore" limit may appear more than one time for a user - like Trash:ignore and Spam:ignore, right? So I assumed following should work - and it does - except for "ignore" - even though LDAP does not hold multiple values for it - only a single one for each limit: user_attrs = [...] mailQuotaStorage=quota_rule=*:storage=%$, mailQuotaMessages=quota_rule2=*:messages=%$, mailQuotaIgnore=quota_rule3=*:ignore=%$ pass_attrs = [...] mailQuotaStorage=userdb_quota_rule=*:storage=%$, mailQuotaMessages=userdb_quota_rule2=*:messages=%$, mailQuotaIgnore=userdb_quota_rule3=*:ignore=%$ And unfortunately /var/log/maillog tells me: dovecot: imap(abuse(a)netocean.local): Error: user abuse(a)netocean.local: Initialization failed: Failed to initialize quota: Invalid quota root quota: Invalid rule *:ignore=Trash: Unknown rule limit name: ignore Yet /var/log/debug.log sounds a bit more promising ... but then again not really ... dovecot: imap: Debug: Added userdb setting: mail=maildir:/usr/local/www/default/mail/user@mydomain.tld dovecot: imap: Debug: Added userdb setting: plugin/quota_rule=*:storage=1048576 dovecot: imap: Debug: Added userdb setting: plugin/quota_rule2=*:messages=10 dovecot: imap: Debug: Added userdb setting: plugin/quota_rule3=*:ignore=Trash dovecot: imap(abuse(a)netocean.local): Debug: Effective uid=2110, gid=2110, home=/var/vmail/user(a)mydomain.tld/mail dovecot: imap(abuse(a)netocean.local): Debug: Quota root: name=User quota backend=maildir args= dovecot: imap(abuse(a)netocean.local): Debug: Quota rule: root=User quota mailbox=* bytes=1073741824 messages=0 dovecot: imap(abuse(a)netocean.local): Debug: Quota rule: root=User quota mailbox=* bytes=1073741824 messages=10 dovecot: imap(abuse(a)netocean.local): Debug: Quota rule: root=User quota mailbox=* bytes=1073741824 messages=10 Additionally, if one of the two working quotas (storage & messages) is exceeded than Dovecot sends out a warning from this setting: plugin { quota_warning = storage=90%% quota-warning 90 %u quota_warning2 = storage=75%% quota-warning 75 %u # What message to send to IMAP clients (and SMTP senders) when quota is exceeded? quota_exceeded_message = Quota exceeded, please go to http://MyDomain.TLD for instructions on how to fix this. } No my question is how to provide two different warnings. One for storage like: Sorry, you're mail storage is full. Please delete some. And a second for messages like: Sorry, you've too many messages. Please delete some. Thanks & Best Regards Leander

Troubleshooting doveadm for Solr Configuration

Re: Uniqueness of dovecot mailbox-guids

If mailbox guids should be unique systemwide, would it be safe to delete all 'dovecot-uidlist' files of the user's mailboxes and then do a doveadm force-resync after mailbox migration? Thanks!

Update: seems to me that the old cyrus mailserver already uses these non-unique mailbox guids. Is it necessary to have them unique over all private namespaces?
