[Dovecot] Error: pipe() failed: Too many open files

Hi, I am currently migrating a big bunch of mail accounts to a dovecot server running 1.0rc2 on Solaris 10 suddenly all imap processes died and I see this in my dovecot.log: dovecot: Sep 26 14:54:31 Error: pipe() failed: Too many open files dovecot: Sep 26 14:54:31 Fatal: dup2(stderr) failed: Bad file number dovecot: Sep 26 14:54:31 Error: child 29376 (imap) returned error 89 dovecot: Sep 26 15:15:48 Error: pipe() failed: Too many open files dovecot: Sep 26 15:15:48 Fatal: dup2(stderr) failed: Bad file number dovecot: Sep 26 15:15:49 Error: child 1563 (imap) returned error 89 dovecot: Sep 26 15:15:55 Error: pipe() failed: Too many open files dovecot: Sep 26 15:15:55 Fatal: dup2(stderr) failed: Bad file number dovecot: Sep 26 15:15:55 Error: child 1572 (imap) returned error 89 dovecot: Sep 26 15:15:58 Error: pipe() failed: Too many open files dovecot: Sep 26 15:15:58 Fatal: dup2(stderr) failed: Bad file number dovecot: Sep 26 15:15:58 Error: child 1577 (imap) returned error 89 dovecot: Sep 26 15:18:25 Error: pipe() failed: Too many open files dovecot: Sep 26 15:18:25 Fatal: dup2(stderr) failed: Bad file number dovecot: Sep 26 15:18:25 Error: child 1659 (imap) returned error 89 dovecot: Sep 26 15:18:27 Error: pipe() failed: Too many open files dovecot: Sep 26 15:18:27 Fatal: dup2(stderr) failed: Bad file number dovecot: Sep 26 15:18:27 Error: child 1662 (imap) returned error 89 dovecot: Sep 26 15:18:32 Error: socketpair() failed: Too many open files dovecot: Sep 26 15:18:32 Error: Temporary failure in creating login processes, slowing down for now dovecot: Sep 26 15:18:32 Error: pipe() failed: Too many open files what could cause the error? is this from Solaris or from dovecot?

[Dovecot] Not getting new mail notification
by Robert Creager 26 Sep '06

26 Sep '06

Hey all, I'm having no luck getting new mail notification except in two mail folders (using maildir w/procmail delivery). I'm using three different clients (sylpheed-claws 1.9.14, Thunderbird 1.5.0.5 and a newer version of Horde). None of them are getting new mail in any except these two folders (inbox and 1 other). If I browse to the folders, still nothing. If I browse to the folders with Horde, I see the new mail, but not always in the other clients. It's hit or miss if the other clients get notified of the mail, but the mail is moved from the new folder. I'm subscribed to the folders and have them to be checked for new messages (in Thunderbird). I tried using dnotify, and things got worse (no folders updated). I've over 350 e-mails sitting in new folders right now: [robert@thunder Maildir]$ ls .*/new | wc 397 332 12925 One interesting item I noticed is that if I touch a file in a new directory (or vi it), I immediately get notification of the mail (and it gets moved from new to cur). I'm running dovecot 1.0 RC7 configured as ./configure --sysconfdir=/etc/dovecot --with-pgsql --with-pam --localstatedir=/var with the following changes to the config: base_dir = /var/lib/dovecot/ protocols = imaps ssl_cert_file = /etc/ssl/dovecot/certs/dovecot.pem ssl_key_file = /etc/ssl/dovecot/private/dovecot.pem default_mail_env = maildir:%h/Maildir verbose_proctitle = yes protocol imap { imap_client_workarounds = tb-extra-mailbox-sep } I'm running dovecot through xinetd: service imaps { disable = no socket_type = stream protocol = tcp wait = no user = root server = /usr/local/libexec/dovecot/imap-login flags = IPv4 server_args = --ssl } Linux thunder.logicalchaos.org 2.6.12-12-3 #5 SMP Wed Feb 1 23:59:03 MST 2006 i686 AMD Athlon(tm) MP 2600+ unknown GNU/Linux Help?

[Dovecot] Preforming an action/trigger after a user successfully authenticates
by Dan Trainor 26 Sep '06

26 Sep '06

Hi - I have searched the docs for v1.0 RC7, but cannot find what I'm looking for. What I'm ultimately wanting to do is have Dovecot preform some action, or a trigger, when the user is successfully authenticated. Even more specifically, I'd like to run another SQL query to record a date/time for last authenticated login. Short from running a script during logrotate, or constantly tailing the log, is there any mechanism in Dovecot that would allow me to do this? Again, all I'm looking to do is to record the last date/time that someone successfully logged in, into a MySQL database. Thanks! -dant

[Dovecot] Dovecot Usage Poll
by Jackie Hunt 25 Sep '06

25 Sep '06

Hi all, I'm trying to get a feel for how many sites are using Dovecot and the size of the installation. Jonathan's query about big sites spurred my curiousity. I'd like to take an informal poll and will post results to the list. I'm interested in hearing from those of you who are using dovecot in a real-life/production type environment (not just testing). Please email me directly [jackie.hunt(a)colostate.edu] and send the following info: (1) Type of organization: commercial/government/educational/etc. (2) Number of users supported with Dovecot (3) Approx. length of time you've used Dovecot in "production" (4) Whether or not you are using the Dovecot LDA Thanks much, Jackie --- Jackie Hunt ACNS Voice: (970) 663-3789 Colorado State University FAX: (970) 491-1958 Fort Collins, CO 80523 Email: jackie.hunt(a)colostate.edu

[Dovecot] DSpam mysql-plugin (was DSpam plugin)
by Michael Blinn 25 Sep '06

25 Sep '06

After wrestling with Johannes's original plugin, I had a go at the mysql plugin that Tim wrote, as described here: http://members.plug.org.au/~linuxalien/dokuwiki/projects:dovecot-mysql-dspa… I kept getting "Error: imap dump-capability process killed with signal 11" when attempting to start dovecot with this plugin. I traced the error to line 656 of master-settings.c in the dovecot source, in the 'get_imap_capability' function. In this function, it notes: "Reloading configuration. Don't try to execute the imap process again. Too risky and the wait() call below will break it anyway. Just use the previous capability list we already had generated." I changed the source so that the function always ran " set->imap_generated_capability = p_strdup(settings_pool, generated_capability); return TRUE;" instead of going through the function where it had on the wait described in the comments. Now, voila. Dovecot starts without complaint, the plugin works, the delivery and moving of email works. I'm assuming I've screwed something up by skipping the rest of this get_imap_capability function. My C skills are a few years rusty. What are the ramifications of skipping the remainder of this function? Thanks, Michael

[Dovecot] Moving to dovecot
by Ian C. Quorn 25 Sep '06

25 Sep '06

We're in the process of moving to Dovecot. We're currently running UW-IMAP live with Dovecot 1.0rc7 on alternate ports for testing. We're set to switch to Dovecot tomorrow morning, and I'm sure I'll have lots of stupid questions once that happens. So I guess you can consider this message an introduction as well as a preemptive apology. Our setup: our mailserver is a SunFire 880 running solaris 8. Inboxes are stored in /var/mail, home directories are in /home. Mailboxes are mbox. Both /home and /var/mail are NFS-mounted from a NetApp filer. Indexes are stored in /dovecot (this is a partition on local disk). We have about 500 users accesing their mail on this server. Supported clients are Outlook, Mac Mail, and Thunderbird (both PC and Mac). Many people access their mail via webmail (IMP Horde) instead of or in addition to using a normal client. We also have a few people who use Pine. Authentication is against the local shadow file. Given this setup, do the following config lines seem sane? login_process_per_connection = no login_max_connections = 256 default_mail_env = mbox:~/mail/:INBOX=/var/mail/%u:INDEX=/dovecot/%u namespace private { separator = / prefix = inbox = yes } # for backwards compatibility: namespace private { separator = / prefix = mail/ hidden = yes } namespace private { separator = / prefix = ~/mail/ hidden = yes } namespace private { separator = / prefix = ~%u/mail/ hidden = yes } mail_read_mmaped = no mmap_disable = no mmap_no_write = no lock_method = fcntl mbox_read_locks = dotlock mbox_write_locks = dotlock imap_client_workarounds = outlook-idle tb-extra-mailbox-sep pop3_uidl_format = %08Xv%08Xu pop3_client_workarounds = outlook-no-nuls oe-ns-eoh The namespace stuff came from http://wiki.dovecot.org/Namespaces - it was listed as a way to allow backwards-compatability with UW-IMAP. So, anything there look like a bad idea? Any other config parameters I might want to tweak, tune, or otherwise take a look at? So far dovecot's been pretty much trouble-free in our testing. But I have noticed some error messages in the logs. Anyone know what these mean? Are they anything I should panic over? dovecot: Sep 25 09:34:19 Error: IMAP(cliftoja): UIDVALIDITY changed (1034876030 -> 1159201281) in mbox file /home/wcts/cliftoja/mail/Common installation codes dovecot: Sep 25 09:50:24 Error: IMAP(cliftoja): UIDVALIDITY changed (1156881790 -> 1159202005) in mbox file /home/wcts/cliftoja/mail/Junk dovecot: Sep 25 10:04:01 Error: imap-login: Master sent reply with unknown tag 180 dovecot: Sep 25 10:04:01 Error: child 1078 (login) returned error 89 dovecot: Sep 25 10:18:58 Error: login: tried to change state 0 -> 44 (if you can't login at all, see src/lib/fdpass.c) Thanks in advance, and here's to (hopefully) a trouble-free Dovecot migration (hey, it can't be worse than UW-IMAP).

[Dovecot] support for UW-style mbox
by T. Horsnell 25 Sep '06

25 Sep '06

Hi, The dovecot docs say that support for the automatic appending of /var/spool/mail to a ~user/mbox (as is done by UW-IMAP) may be implemented in the near future. Is this still the case? And if so, is it far off? Cheers, Terry.
