[Dovecot] Bug: Fixed a duplicate
by Tom Sommer 06 Jun '11

06 Jun '11

I restored a dovecot mailserver today, and when I started the server again, the logs filled up with "Fixed a duplicate" warnings. This in itself it not a problem, the problem is that it appears the fix is not done correct. Consider this: Warning: Fixed a duplicate: [X]/cur/1305907573.V807I37682f3M146183.mail8.xxx.com:2,S -> 1306601066.M382668P27710.mail8.xxx.com The problem appears to be the timestamp of this new file isn't updated correctly. Now I got hundreds of mailboxes filled with mails named 1305907573.* with random (in the past) timestamps, leading to mangled miss-sorted inboxes for customers. 3575 May 25 02:05 1306600913.M982997P26976.mail8.xxx.com:2,S 55313 May 6 01:50 1306600913.M982998P26976.mail8.xxx.com:2,S 9839 May 7 23:59 1306600913.M982999P26976.mail8.xxx.com:2,S 3453 May 10 01:32 1306600913.M983000P26976.mail8.xxx.com:2,S 16616 May 14 00:22 1306600913.M983001P26976.mail8.xxx.com:2,S 68850 May 25 00:46 1306600913.M983002P26976.mail8.xxx.com:2,S etc. Dovecot is v. 2.0.11 I guess I should have deleted all dovecot.* files after the restore, before I started dovecot? // Tom

[Dovecot] Custom sql query for keeping quota with dict-sql
by Marcin Mirosław 05 Jun '11

05 Jun '11

Hello! I'd like to setup quota for for virtualusers, i'm using both maildir++ and mdbox as storage, and i'm using postgresql to keep users. I'm keeping all users data in one table: [...] login text NOT NULL, domain text, password text, quota_mb integer NOT NULL DEFAULT 0 [... other columns ...] i'd like to keep present quota in such two columns: quota_dict_bytes integer NOT NULL DEFAULT 0, quota_dict_messages integer NOT NULL DEFAULT 0 I read wiki a little and it looks i can't define own sql queries, they appear to be hardcoded. Am i wrong? Is it possible to write own queries to get/set quota using such table schema? Or maybe there is diffrent way to track quota for diffrent storages? Regards! Marcin

[Dovecot] dsync: Invalid mailbox first_recent_uid
by David Jonas 04 Jun '11

04 Jun '11

For the life of me I can't get dsync to work. Please help! Remote server runs dovecot out of /usr/local/dovecot2. Everything makes sense until this line: dsync-local(djonas(a)vitalwerks.com): Error: Invalid mailbox input from worker server: Invalid mailbox first_recent_uid The local uid is 8989 and the remote uid is 89. I added "first_valid_uid = 89" to the local conf but to no avail.

[Dovecot] solr substring schema.xml
by Daniel Miller 03 Jun '11

03 Jun '11

I'm trying a modified schema.xml with solr - it appears I now have substring searches! I took the schema.xml file shipped with Dovecot, and modified the text field definition to be: <fieldType name="text" class="solr.TextField" positionIncrementGap="100"> <analyzer type="index"> <tokenizer class="solr.WhitespaceTokenizerFactory"/> <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt"/> <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="1" catenateNumbers="1" catenateAll="0"/> <filter class="solr.LowerCaseFilterFactory"/> <filter class="solr.SnowballPorterFilterFactory" protected="protwords.txt"/> <filter class="solr.NGramFilterFactory" minGramSize="3" maxGramSize="15"/> <filter class="solr.RemoveDuplicatesTokenFilterFactory"/> </analyzer> <analyzer type="query"> <tokenizer class="solr.WhitespaceTokenizerFactory"/> <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/> <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt"/> <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="0" catenateNumbers="0" catenateAll="0"/> <filter class="solr.LowerCaseFilterFactory"/> <filter class="solr.SnowballPorterFilterFactory" protected="protwords.txt"/> <filter class="solr.RemoveDuplicatesTokenFilterFactory"/> </analyzer> </fieldType> Changing to the new "SnowballPorter" instead of the deprecated "EnglishPorter" filters is probably minor - the magic is the "NGramFilterFactory". 3 & 15 seemed reasonable defaults for the min/max size to search on. -- Daniel

[Dovecot] unexpected subfolder locaton in Maildir/.INBOX.subfolder
by wulf 03 Jun '11

03 Jun '11

Hallo, I try to migrate existing imap server to dovecot 1.2 in debian squeeze if I connect to imap://user@host/INBOX Inbox works as expected and I get the content of Maildir/{cur,new,tmp} Maildir/.subfolder already exists if I connect to imap://user@host/INBOX.subfolder I get "folder not found" if I do a imap directory listing (raw mutt config, no subscriptions) - I see "../" - If I navigate to "../" I se all my existing subfolders if I create a new folder via imap the folder is created in Maildir/.INBOX.new_subfolder I expect the creation of Maildir/.new_subfolder This doesn't fit to the client configs and if I move the existing folders it doesn't fit to existing delivery agent filters and settings. I enabled mail_debug and the expansion looks ok for me: dovecot: imap-login: Login: user=<wulf>, method=PLAIN, rip=85.178.xx.xxx, lip=80.81.xxx.xxx, TLS dovecot: IMAP(wulf): Effective uid=112, gid=114, home=/var/mail/home/wulf dovecot: IMAP(wulf): maildir: data=~/Maildir dovecot: IMAP(wulf): maildir++: root=/var/mail/home/wulf/Maildir, index=, control=, inbox=/var/mail/home/wulf/Maildir the existing subscription information from courier-imap looks like INBOX.subolder Yes I can sed them to subfolder (of course I have to copy them to Maildir/subscriptions anyhow) But is that the idea? I like to avoid trouble with all the users and their already configured mail-clients. Where is my mistake? Thanks for feedback Best Wulf CONF: protocols = imap imaps log_timestamp = "%Y-%m-%d %H:%M:%S " ssl = required ssl_cert_file = /etc/exim4/xxxxxxxxxxxxxxx.pem ssl_key_file = /etc/exim4/xxxxxx.key mail_location = maildir:~/Maildir mail_uid = 112 mail_gid = 114 mail_access_groups = vmail mail_debug = yes first_valid_uid = 112 protocol imap { } protocol pop3 { pop3_uidl_format = %08Xu%08Xv } protocol managesieve { } auth_verbose = yes auth_debug = yes auth default { mechanisms = plain passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } userdb static { args = uid=112 gid=114 home=/var/mail/home/%u } user = root } dict { } plugin { } dovecot-ldap.conf: hosts = 127.0.0.1:389 auth_bind = yes auth_bind_userdn = uid=%u,ou=users,dc=xxxxxxxx,dc=de base = dc=xxxxxxxx,dc=de

[Dovecot] Running a dovecot cluster with mixed versions?
by Ian Foutch 03 Jun '11

03 Jun '11

I have been trying to find information and possible issues with running a cluster of dovecot server with different versions without any luck. We have an existing cluster with dovecot v1.1.10 and tried migrating to a new cluster with dovecot v2.0.12. We ran into some issues when we moved traffic to the new cluster and have been unable to reproduce it in our own testing. We may need to put real usage on the new servers but would like to be able to do this by adding newer servers into the existing cluster. What are the potential issues with doing this?

[Dovecot] Problems in auth when switching from PLAIN-MD5
by Eduardo Casarero 03 Jun '11

03 Jun '11

Hi, i am running dovecot 2.0.11 (with mysql backend) and until now using PLAIN-MD5 as pass default_pass_scheme everything was working fine. However i wanted to change the pass_scheme to something stronger than plain-md5, so i started by reading the wiki. I found this: http://wiki2.dovecot.org/HowTo/ConvertPasswordSchemes But when i comment out "default_pass_scheme" and i create the pass with the {SHA256.hex} prefix i see this in the logs: auth: Error: sql(xxx(a)xxxxxx.com,10.21.1.1): Password in passdb is not in expected scheme SHA256.hex I tried with several algorithms, but it seems to be something in my config that it's only working with plain-md5. the auth_mechanism is plain with ssl/tls. Maybe someone can give me a hint of where to see o which config file review. Thanks in advance. Eduardo.

[Dovecot] slow squat fts index creation
by Cor Bosman 03 Jun '11

03 Jun '11

Hi all, ive been playing with squat indexes. Up to about 300.000 emails in a single mailbox this was working flawlessly. The search index file is about 500MB at that time. Ive now added some more emails, and at 450.000 or so emails im seeing a serious problem with squat index creation. It takes...f o r e v e r . The .tmp file is being so slowly, it will probably take 2-3 hours to create. Upto this point it took maybe a minute. Im doing this in an openvz container, so theoretically i may be hitting some openvz resource limit. But ive upped all the limits and dont see any improvements. I dont see any resources starvation either. Could there be some dovecot issue when the search index reaches say 1GB? (im estimating that it's now trying to save about 1GB search index). Regards, Cor
