[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

[Dovecot] passdb: password contains illegal chars question
by Torsten Krah 03 Jun '11

03 Jun '11

Hi, some question about passdb backend: I'll receive this (using dovecot 2.0.13, pgsql passdb backend) for some users: mail dovecot: auth: passdb(account-username,127.0.0.1): Attempted login with password having illegal chars Password schema ist crypt-md5. So what "chars" does dovecot not like (why?) and whats the preferred way to fix this? regards Torsten -- Bitte senden Sie mir keine Word- oder PowerPoint-Anhänge.
