[Dovecot] Unit testing
by Timo Sirainen 09 May '09

09 May '09

Unit testing is slowly going forward in Dovecot. In v2.0 tree all the unit tests are now run when you do "make check". They're also run on "make distcheck", which is what I use when building releases or nightly snapshots. So as soon as I start building nightly v2.0 snapshots I should start getting mails every night if the unit tests fail. And I can no longer make a release if a unit test fails. (Unit tests never get run manually - I once fixed a unit test that had been failing for months.) Besides that, I started trying to add unit tests to lib-index. After some hours of refactoring the code I finally managed to get mail-transaction-log-view and mail-index-transaction to a condition where unit tests could be added to them without too much pain. I didn't really add that many unit tests there yet though. I'll probably slowly continue adding more tests and refactoring the code more to allow more unit tests, but if anyone else finds they have nothing better to do, now's a good time to add more tests :) Especially lib/, lib-mail/ and lib-imap/ should already be easily testable and they're missing a lot of tests.

[Dovecot] dovecot slowing down
by P.A 08 May '09

08 May '09

Hi, not really a dovecot issue but, im running dovecot 1.0.10 with no issues for awhile now J. However I ran into an issue today where postfix didn't have enough processes to handle incoming smtp connections. This for whatever reason was causing pop/imap (dovecot) to take a long time to respond on the appropriate port. After looking at server and finding nothing wrong I stopped postfix which got rid of the delay on port 110/143. I then turned on postfix again and saw the delay for port 25/110/143. What I then did was adjust/increase the default_process_limit in postfix which took care of the problem. Question is why would not enough processes in postfix slow other services down like dovecot 110/143? There was plenty of bandwith/mem/cpu left.

[Dovecot] mailutil?
by Timo Sirainen 08 May '09

08 May '09

dbox format needs at least two tools: 1. Expunging only marks the message having refcount=0. The actual disk space is freed only after calling a tool pointing to the user's dbox dir. 2. Ability to force index resync/rebuild in case it doesn't figure out itself that there's something wrong. I'm starting to think about building a more generic mailutil tool, maybe something similar to what UW-IMAP has. So two questions: - What should the tool be called? Probably not mailutil to avoid confusion. doveutil? dovemail? dovetool? mailtool? - Is there any functionality you'd like it to do?

[Dovecot] Imap notifications in IDLE
by Jarosław Przybyłowicz 07 May '09

07 May '09

Hi, could you please tell me if there is a way, to make dovecot notify my mail client of new messages in inbox subfolders? I'm using fdm to fetch mails into maildir and proper subfolders. So far, when idleing mozilla gets a notification when new message arrives in INBOX, but if mail is fetched into other folder I have to click on it to see if there is a new message. I've checked thunderbird imap log to check if this is dovecot or TB issue. Is there any way to force dovecot to monitor other folders? Regards, V

[Dovecot] authentication to IMAP
by punit_j 07 May '09

07 May '09

HI All, Is there a way to do admin authentication for a normal user in dovecot IMAP ? I have a user using PAM to store password in /etc/shadow file. I need to authenticate the user in IMAP using that password. I tried using : - I tried all combinations as below [root@mail ~]# cat /etc/shadow| grep -i ajay ajay.lal:CM730q8foSA9A:13545:0:99999:7::: [root@mail ~]# telnet 0 143 Trying 0.0.0.0... Connected to 0 (0.0.0.0). Escape character is '^]'. * OK dovecot ready. a1 login ajay.lal CM730q8foSA9A a1 NO Authentication failed. a1 login ajay.lal "{crypt}CM730q8foSA9A" a1 NO Authentication failed. Also i tried [root@mail ~]# perl -MMIME::Base64 -e 'print encode_base64("\0ajay.lal\0{crypt}CM730q8foSA9A");' AGFqYXkubGFsAHtjcnlwdH1DTTczMHE4Zm9TQTlB [root@mail ~]# telnet 0 143 Trying 0.0.0.0... Connected to 0 (0.0.0.0). Escape character is '^]'. * OK dovecot ready. a1 AUTHENTICATE PLAIN + AGFqYXkubGFsAHtjcnlwdH1DTTczMHE4Zm9TQTlB a1 NO Authentication failed. My dovecot server does PLAIN authentication as can auth_mechanisms = plain Is there a way to do PLAIN auth with crypt password or any means of doing admin authentication on behalf of normal user ?

[Dovecot] Solr FTS issues (Was fts-solr plugin issue (Marked invalid))
by Dror Matalon 06 May '09

06 May '09

Hi, Sorry for the change of thread, I just signed up to the list so I couldn't reply to the earlier message. Let me clarify the issue that Nikolai was describing. We're running dovecot 1.1.11 and solr 1.4. The issue is quite simple. 1. I run a search. 2. Dovecot sends a list of emails to solr 3. Solr starts indexing them 4. Solr runs into a "bad" email and we get: SEVERE: java.io.IOException: Mark invalid org.apache.solr.common.SolrException log SEVERE: java.io.IOException: Mark invalid at java.io.BufferedReader.reset(BufferedReader.java:485) at org.apache.solr.analysis.HTMLStripReader.restoreState(HTMLStripReader.java:171) at org.apache.solr.analysis.HTMLStripReader.read(HTMLStripReader.java:728) at org.apache.solr.analysis.HTMLStripReader.read(HTMLStripReader.java:742) at java.io.Reader.read(Reader.java:123) at org.apache.lucene.analysis.CharTokenizer.next(CharTokenizer.java:109) at org.apache.lucene.index.DocInverterPerField.processFields(DocInverterPerField.java:159) at org.apache.lucene.index.DocFieldConsumersPerField.processFields(DocFieldConsumersPerField.java:36) at org.apache.lucene.index.DocFieldProcessorPerThread.processDocument(DocFieldProcessorPerThread.java:234) at org.apache.lucene.index.DocumentsWriter.updateDocument(DocumentsWriter.java:765) ... 5. All the above email messages that were indexed are rolled back, and we're stuck. I think that the solution should be simple too :-). When solr runs into a bad email, it should just ignore it and keep indexing. This seems much more robust since the emails are coming from a variety of sources, and we can assume that some of them are going to generate badly formated emails. Seems like having a few bad emails not indexed is much better than the current situation of a bad email stopping all searching. I don't understand the architecture enough between fts, fts_solr and solr to know where this should be solved. Ideally, it would be a simple directive to solr.
