Re: [Dovecot] Slow connections with POP3 service

Great. Thank you so much for responding. It hangs at Tying 127.0.0.1 The funny part is that one day it works fine and the next day it just hangs. And its not that the service is completely unresponsive. If 200 users try to connect, 10 get through and are able to download. However which 10 get through depends on luck! Its been going on for the past one week and really driving me crazy. I have changed everthing including the server, but the problem persists. How do I get a clue where the problem is? Am badly in need of help here.

[Dovecot] fts-solr plugin issue (Marked invalid)
by Nikolai Derzhak 01 May '09

Hi. We user ftp-solr plugin and have problem with solr-1.3+ with HTMLStripWhitespaceTokenizerFactory (Solr schema in attachments). In some maildir's present messages with wrong "Content-Type: " fields in attachments. For example: " Content-Type: TEXT/mspowerpoint; name="Zapatec_6zap_netvibes_1.ppt" " Indexing for this messages is stop with "fts_solr: Indexing failed: 500 Internal Server Error". In solr log is: " SEVERE: java.io.IOException: Mark invalid at java.io.BufferedReader.reset(BufferedReader.java:485) " (mail list with discussion: http://markmail.org/message/2fnfiwygvehjngyr#query:SEVERE%3A%20java.io.IOEx…) Look's like dovecot try to index attachments like this. Also for some messages we have same error. Dovecot stop indexing of box and each search we have lag and CPU load on server. So we need to make dovecot more "stable" to this error. For first time , will be good, just ignore problematic messages with error from solr. Let's discuss this issue, because this is general problem. We ready to explore code where needed , etc. Regards, Nikolai Powered by the 6zap. Sign up at http://www.6zap.com for an account that provides advanced e-mail, calendar and contacts capabilities.

The only thing I don't understand and can't find/understand in the documentation is how to tell the LDA where to put my e-mails.

[Dovecot] Installed include files
by Timo Sirainen 01 May '09

01 May '09

Currently when using configure --enable-header-install and doing make install the include files get installed to their own subdirectories, like: /usr/local/include/dovecot/src/lib/ /usr/local/include/dovecot/src/lib-mail/ ..etc.. But using that is kind of annoying, because you have to give -I paths to all of them with their full directories. The worst thing about that is that it requires having some kind of a --with-dovecot=path configure parameter. It would be nice if you could simply do: CPPFLAGS=-I/usr/local/include/dovecot ./configure Just like for any other include option. But that's not really possible. One possible way to fix it would be to just install all the .h files to a single directory, /usr/local/include/dovecot/ and make sure there aren't any conflicts (there currently are a few). But whis would make it more difficult to find out what files are related. Another possibility would be to put the subdir paths to all #include lines. Such as #include "lib-mail/mail-types.h" instead of just #include "mail-types.h". This seems kind of annoying to use, but would it be clearer? I'm not really sure. Anyone have any thoughts?

[Dovecot] Case sensitive oddity when mail delivered.
by dovecot＠corwyn.net 01 May '09

01 May '09

Currently running Postfix/Dovecot1.1.8 with mysql storing the user data and delivering to folders as determined by dovecot using dovecot's "deliver" as defined in postfix's master.cf Mail location is determined by mail_location = maildir:/var/spool/mail/%d/%n/Maildir If I have an account user1(a)example.com it works just fine. However, when mail is sent to USER1(a)EXAMPLE.COM it also delivers, but ends up creating a new file structure so I end up with /var/spool/mail/example.com/user1 (with lower case mail in it) and /var/spool/mail/EXAMPLE.COM/USER1 (with uppercase mail in it) which is decidedly not good. Looks to me like wherever %d and %n are pulled from is pulled out of the email, but not lower-cased. Any ideas where I would look to change this value before the email is delivered to the mailbox? Thx. rick Rick Steeves http://www.sinister.net "Life is like a sausage: The more you pack into it, the longer it gets"

[Dovecot] How to call a script when an E-Mail will moved in a folder?
by Luca Bertoncello 30 Apr '09

30 Apr '09

Hi, list! I use Dovecot 1.1.14 at work. It is configured to manage IMAP and IMAPs. Exim is the MTA of the Network. Of course, I installed SpamAssassin and ClamAV to check all incoming E-Mails. An, of course, some E-Mail marked as Spam are Ham and some E-Mail marked as Ham are Spam... To teach SpamAssassin I create for every user two folder: "DochSpam" (for Spam E-Mails not marked) and "FalscheSpam" (for Ham E-Mails marked as Spam). Every hour a cronjob search for E-Mails in these folders and call sa-learn to teach SpamAssassin. All run perfectly, but I'd like to modify this method and call automatically the script when the user move an E-Mail to DochSpam or FalscheSpam. I searched in Google, but I cannot found any useful link... How can I trigger an action (script calling) based on event (E-Mail will be moved to a folder) in Dovecot? Thanks for your help!

I just tested the quota-warning, with the dovecot-deliver-example. Exactly the same time as the mail exceeding the quota-percentage is delievered in the account, the quota-warning-message is generated and also delivered. > Anyway, we are neither sending an email nor using deliver.

But the script that should do that is never run by dovecot > :-( Try the injection using deliver, and use the "alternative script" from the wiki-page as quota_warning. I just tested it, works great. Also: when using dovecot-deliver, the maildir-indizes are being generated better and faster than with alternative MDAs. Best regards, Anton

[Dovecot] Unexplainable problem with POP3 quotas
by Marco Marongiu 30 Apr '09

30 Apr '09

Greetings * We are having a problem with POP3 quota warnings, and despite we dig into the documentation, mailing list archives, google... we didn't spot any light We are running a self-compiled dovecot 1.1.7. The user base is in a Postgres database. We'd like a quota warning message to be injected into the maildir at 80% and 95% of occupation reached. >From the logs, it looks like dovecot is correctly reading the quotas from the DB. Nevertheless, the warning message is never delivered. We tried many different configurations (e.g.: from using bytes instead of storage to change the quota configuration alltogether, I think we tried every single sensible, applicable solution that we could spot during our searches in the net). Currently, we have the following non-working one: root@mgo2-popimap-v01:/usr/local/dovecot/etc# ../sbin/dovecot -n # 1.1.7: /usr/local/dovecot_1.1.7/etc/dovecot.conf Warning: fd limit 1024 is lower than what Dovecot can use under full load (more than 16384).

All my users are on a LDAP database integrated via nss_ldap, so from the dovecot point of view they are all local system users. Now I want to set maildir quota for everybody, and was wondering if I could store quota limits per user on LDAP. As I read on http://wiki.dovecot.org/Quota/Dict, there seem to be no way to do that, am I right? It is ok for me to manage the current usage on Maildir++, but would like to retrieve the quota information from the LDAP server. What do you guys recommend? Thanks in advance for any hint or rtfm. Best regards. -- Marcio Merlone

[Dovecot] Dovecot v2.0 hg tree
by Timo Sirainen 29 Apr '09

29 Apr '09

http://hg.dovecot.org/dovecot-2.0/ I just did the initial commit for master process rewrite, which marks the beginning of Dovecot v2.0. Several things are still missing/broken, but at least I was just able to successfully log in using imap :) I left v1.3 hg tree there for now, but once v2.0 tree is fully usable I'll just delete the v1.3 tree. Note the new dovecot-master-example.conf, which you'll need to !include to get the services running. Some settings have also been removed because they're now more generically set in the dovecot-master.conf. I'm thinking that perhaps the config process could still be run in compatibility mode where it's able to use an existing v1.x dovecot.conf and translate the old settings to new settings.

[Dovecot] Slow connections with POP3 service
by V S Rao 29 Apr '09

29 Apr '09

Hi All, I am facing a very strange issue with the pop3 server for the past one week. I run my mail service using sendmail & use UW-IMAP for POP3 & IMAP service. We have around 5000 users. Suddenly for the past one week I am facing very slow connections for POP3 alone on that server. Other services such as SMTP, IMAP, telnet, ssh etc work fine. Assuming that UW-IMAP may have an issue, I download the latest dovecot, compiled it and installed it. This also gives the same issue. I do not any firewall issues nor iptables is enabled. I have checked on the network to ensure that I do not have any kind of virus or DoS attacks using an IDS. I am unable to see any 'Strange' messages in /var/log/messages or maillog. What is strange is that it works one day without any issues and the next day the problem persists. Even a telnet to localhost on port 110 is very very slow. Can someone help with any ideas on how to troubleshoot? This is our production box. Thanks V S Rao

[Dovecot] Links on MainConfig wiki page not working
by Matthijs Kooijman 29 Apr '09

29 Apr '09

Hi all, while looking through the wiki page MainConfig, I noticed a lot of wannabe-links, for example: <doc/wiki/SSL> This looks like it should have been converted to a wiki link automatically, but apparently isn't. Would be good to have this fixed? Gr. Matthijs

[Dovecot] Quota/Dict Postgres Trigger
by Warren Volz 29 Apr '09

29 Apr '09

I posted the trigger for v1.1 versions of Dovecot on the Wiki (http://wiki.dovecot.org/Quota/Dict ) and while I understand the comment posted about two process inserting at the same time, I'm not sure I understand how this is fixed in v1.2 other than via the revised trigger in the Wiki. Does someone have a known working trigger that will handle a double insert correctly? Also, out of curiosity why wasn't the code for dict written to do an update first and then an insert if this failed? That would eliminate the need for this trigger. Thanks. -Warren

[Dovecot] Mail statistics
by Timo Sirainen 29 Apr '09

29 Apr '09

I just committed a mail statistics gathering patch to v1.2: http://hg.dovecot.org/dovecot-1.2/rev/fdaf0bda70d5 It keeps track of: struct mail_private { .. /* open(), stat(), .. */ unsigned long stats_dentry_lookup_count; /* fstat() mostly */ unsigned long stats_attr_lookup_count; /* number of files we've opened and read */ unsigned long stats_files_read_count; /* number of bytes we've had to read from files */ unsigned long long stats_files_read_bytes; /* number of cache lookup hits */ unsigned long stats_cache_hit_count; So it's possible to write a plugin that does whatever with those values. You can get them per-command or even per-single-mail-access. Any thoughts on if those are good variables? Like would it be useful to split dentry lookups to opens and stats?
