[Dovecot] Too many open files
by Harrison Metzger 10 Jan '08

10 Jan '08

Hello, I have dovecot installed and it works for about 3 hours then I get this error (in /var/log/maillog): Jan 8 08:42:53 stu dovecot: auth(default): pam(grossmsm,69.131.100.47): pipe() failed: Too many open files I set pam_limits.so to allow the user 'dovecot' to have 8192 open files, and I also changed: login_process_size = 512 However, it still wont work for more than a few hours. When I run: lsof -p `ps -o pid= -C dovecot-auth` I get: [...] dovecot-a 1385 root 248u sock 0,5 374241289 can't identify protocol dovecot-a 1385 root 249u sock 0,5 374241391 can't identify protocol dovecot-a 1385 root 250u sock 0,5 374243642 can't identify protocol dovecot-a 1385 root 251u sock 0,5 374241701 can't identify protocol [...] And the number followed by a u keeps growing. As of writing this email that number is now at 274u. Is dovecot not closing its fd's or something? Harrison Metzger

[Dovecot] OT: ctimes
by Jeff Grossman 10 Jan '08

10 Jan '08

I am going to convert my 32-bit Debian system to a 64-bit Debian system today. But, after I move my maildir files over to the new hard drive the ctimes are going to get modified to current time and mess up my automatic purge scripts for the Deleted Items folders. Is it possible for me to either keep the existing ctimes or is it possible for me to modify the ctimes to the date headers of the emails after I move the files? Thanks, Jeff

[Dovecot] Dovecot indexing questions
by Asheesh Laroia 10 Jan '08

10 Jan '08

I was playing with Dovecot 1.1 full text indexing through Squat in late October, which was working pretty well. I wanted to ask about this behavior I had: When an email arrives in INBOX using procmail (which delivers to my Maildirs), and I see it in Dovecot, when I next do a search (IMAP SEARCH TEXT) of that folder, the search takes a long time. Successive searches are lickety-split. My question is: Can there be an option to "index greedily"? As soon as Dovecot sees the message, I'd like it to update the Squat index. That way, searches are always fast. I guess this implies a small performance hit - namely, that my IMAP server spends CPU and disk time indexing every message at the first time it is seen rather than being able to do batch indexing each time SEARCH TEXT is issued. But when I think about that, that sounds like the server can waste its time so I don't waste mine - which is exactly why I like these computing machines! (That, and because I can waste my time programming them.) -- Asheesh. -- Use extra care when cleaning on stairs.

[Dovecot] Logging to stderr
by Abhijit Hoskeri 10 Jan '08

10 Jan '08

Hi, I am having a bit of a problem with logging to stderr. I am trying to run dovecot as sort of "inetd" install using daemontools. I have daemontools 'services' named dovecot-pop3, dovecot-imap, etc. The service command line looks like tcpsvd -c20 -v -l 0 0 110 /usr/lib/dovecot/pop3-login [--ssl] In dovecot/dovecot.conf, the log_path is set to /dev/stderr. What seems to be happening is that all the log lines (regardless of service) go to the log file of which ever service was first used. Exactly how are these logs written? Is it possible to (easily) make the login process write to its own stderr? Thanks, -Abhijit

Does the Trash plugin in 1.0.x log it's dirty deeds somehow? I'd like to see that it works :) -- Ralf Hildebrandt (Ralf.Hildebrandt(a)charite.de) plonk(a)charite.de Postfix - Einrichtung, Betrieb und Wartung Tel. +49 (0)30-450 570-155 http://www.arschkrebs.de Arguing with good advice will result in lack of good advice. -- Victor Duchovni

[Dovecot] Sendmail, procmail, dovecot and quota
by papi mac 10 Jan '08

10 Jan '08

I have Fedora 7 from a standard installation running sendmail, procmail and dovecot 1.0 installed on a single partition. I now need to set up mail quotas for most of the users but not all. Just protecting /var/spool/mail/$LOGNAME is probably good enough for me. Since I just want mail quotas and the installation is on just 1 partition I don't have an easy way to use file system quotas. By reading through the dovecot documentation and list archives I have the feeling that this is possible with the versions and setup I have. I would probably need a main line like this (apart from other lines) per user mailbox that needs to be managed: dirsize:/var/spool/mail/joe-user:storage 10240 to give joe-user a 10 mb limit. Since this server is in production I don't have the luxury of experimenting (extensively) on it. I have a question though that I have not been able to answer yet. If the flow of mail goes from sendmail to procmail to the mailbox, how is it possible for dovecot to implement quotas on the inbox? Or would dovecot write something there that procmail has to honor? Is dovecot the way to do this? Am I misunderstanding what "quotas" mean in dovecot? Thanks for any clues. --------------------------------- Looking for last minute shopping deals?

Hi, I have Heimdal Kerberos with authentication in my Samba PDC, Postfix and OpenLDAP, it is perfect. But, I have problem with authentication GSSAPI of Dovecot. I install a service ticket of the form imap/mailserver.domain.com@REALM, imap/mailserver@REALM, pop/mailserver.domain.com@REALM and pop/mailserver@REALM and /etc/krb5.keytab for this services tickets. Debug in my messages log: Jan 9 15:14:32 mailserver dovecot: auth(default): client in: AUTH^I1^IGSSAPI^Iservice=IMAP^Ilip=192.168.0.71^Irip=192.168.0.212 Jan 9 15:14:32 mailserver dovecot: auth(default): gssapi(?,192.168.0.212): Obtaining credentials for imap@mailserver Jan 9 15:14:32 mailserver dovecot: auth(default): gssapi(?,192.168.0.212): While importing principal name: An invalid name was supplied Jan 9 15:14:33 mailserver dovecot: auth(default): client out: FAIL^I1^Itemp Jan 9 15:14:33 mailserver dovecot: imap-login: Aborted login: method=GSSAPI, rip=192.168.0.212, lip=192.168.0.71 Someone knows solve this problem?

[Dovecot] dovecot upgrade
by Paul A 08 Jan '08

08 Jan '08

Hi, I'm currently using Dovecot version 1.0 and I want to update it to the latest version. I know from version .99 to version 1.0 I had to change a few things on the dovecot config. When compiling the latest stable version should I just be able to use the same config I'm using for version 1.0 without making any changes ? Thank you Paul
