[Dovecot] Growing pools and disconnects
by mmaurer＠betterbe.com 17 Feb '06

17 Feb '06

Since a couple of hours I see *a lot* of the following messages in my maillog: Feb 17 15:37:35 defiant dovecot: imap(mmaurer(a)betterbe.com): Growing pool 'maildir_uidlist_sync' with: 32768 Feb 17 15:37:35 defiant dovecot: imap(mmaurer(a)betterbe.com): Growing pool 'maildir_uidlist_sync' with: 65536 Feb 17 15:37:35 defiant dovecot: imap(mmaurer(a)betterbe.com): Growing pool 'maildir_uidlist_sync' with: 131072 This happens also when viewing small inboxes (but the number being ~1024). This is dovecot 1.0.beta2, which has been running for about 2 days. Any indication where this message is coming from? The first day we never saw this message appearing. Dovecot now also seems to randomly disconnect people from time to time. Any insights would be appreciated. Marc

[Dovecot] Authentication failing - Ant Internet Suite (Risc-OS)
by Simon Waters 17 Feb '06

17 Feb '06

Switched to using dovecot for POP3, PLAIN login. One client with "Ant Internet Suite" can't use the service with this client, he used the same setting with another email client and it worked. On inspection of the packets, it is sending one packet with; "user username\r\npass password\r\nstat\r\n" Dovecot sends an "-ERR Unknown command", then a "+OK Logged in". I'm wondering if things got out of sequence here, since a "STAT" to dovecot before authentication causes the "Unknown command" error. "STAT" isn't allowed in the authentication stage... but well it issued it last.... Anyway I'm unclear here on the precise details of the packet trace, possible it is responding to an earlier packet, but thought I'd ask before pursuing this further in case some one leaps up and says "oh that'll be...". The client software has an option to disabled "queued commands" buried deep within it (append /ucb to user details), I suggested trying this if possible, will report back if it works. Also mentioned in a Google search. I'm curious as to what is right here, but the "/ucb" is presumably the practical answer if it works. Simon

[Dovecot] 1.0beta3 released
by Timo Sirainen 17 Feb '06

17 Feb '06

Since there have been so many requests, I guess it's time for beta3 now. There are a couple of issues that I'm still concerned about, but those probably happen with beta2 as well. If you're beginning to see more connection hangs/timeouts with this release, please tell me. * Dotlock code changed to timeout faster in some situations when the lock file is old. + Added support for loading SQL drivers dynamically (see INSTALL file for how to build them) + Keywords are stored to dboxes, and other dbox improvements. + dict-sql could actually work now, making quota-in-sql-database possibly working now (not fully tested) + Added mail storage conversion plugin to convert automatically from one mailbox format to another while user logs in. Doesn't preserve UIDVALIDITY/UIDs though. + Added plugin { .. } section to dovecot.conf for passing parameters to plugins (see dovecot-example.conf). + Added ssl-build-param binary which is used to generate ssl-parameters.dat. Main dovecot binary doesn't anymore link to SSL libraries, and this also makes the process title be clearer about why the process is eating all the CPU. - Fix building without OpenSSL - Fixed memory leak in MySQL driver - Fixes to checkpassword - Broken Content-Length header could have broken mbox opening - Fixed potential hangs after APPEND command - Fixed potential crashes in dovecot-auth and imap/pop3-login - zlib plugin now links with -lz so it could actually work - kqueue fixes by Vaclav Haisman

[Dovecot] Support of M-IMAP?
by Peter Hessler 16 Feb '06

16 Feb '06

I was looking at some new mobile phones, and apparently there is a form of IMAP that is optimized for mobiles called M-IMAP. Its not a rush (since I'm not even sure the phones will be out before Q2), but it'd be a cool thing to have. The spec is in the following PDF. http://www.3gpp2.org/Public_html/specs/X.S0016-311_v1.0_022404.pdf -- Klein bottle for sale ... inquire within.

[Dovecot] maildir and stat
by David Spidley 16 Feb '06

16 Feb '06

Hi. I plan to use dovecot on nfs with maildir. Does dovecot need to stat each file in a maildir, or does it just read a list of files in the directory? i.e. does it do the equivalent of an ls -f, or an ls -l? HYCH

[Dovecot] ugly hack to make maildir quotas work
by Joshua Goodall 16 Feb '06

16 Feb '06

Timo encouraged me to forward this to the list. Basically it pokes the right value into the right place to make quota deltas work properly when saving mail to Maildirs. It's a nasty hack workaround, so don't rely on it without understanding that it should be superseded in future. Without this, saving to a maildir doesn't increment quota. --- src/lib-storage/index/maildir/maildir-save.c 14 Jan 2006 18:47:50 -0000 1.64 +++ src/lib-storage/index/maildir/maildir-save.c 16 Feb 2006 04:32:49 -0000 @@ -9,6 +9,7 @@ #include "str.h" #include "maildir-storage.h" #include "maildir-uidlist.h" +#include "index-mail.h" #include <stdio.h> #include <stdlib.h> @@ -233,6 +234,7 @@ struct utimbuf buf; const char *path; int output_errno; + struct stat st; if (ctx->failed && ctx->fd == -1) { /* tmp file creation failed */ @@ -264,6 +266,9 @@ "fsync(%s) failed: %m", path); ctx->failed = TRUE; } + if (fstat(ctx->fd, &st) < 0) { + ctx->failed = TRUE; + } if (close(ctx->fd) < 0) { mail_storage_set_critical(STORAGE(ctx->mbox->storage), "close(%s) failed: %m", path); @@ -297,6 +302,8 @@ if (mail_set_seq(dest_mail, ctx->seq) < 0) return -1; + + ((struct index_mail *)dest_mail)->data.physical_size = st.st_size; } t_pop(); /k -- Josh "Koshua" Goodall "as modern as tomorrow afternoon" joshua(a)roughtrade.net - FW109

[Dovecot] Question regarding 'dovecot-auth'
by Paul E Virgo 16 Feb '06

16 Feb '06

Hello Timo, I am compiling dovecot-1.0.beta3, and I get the following message when the dovecot-auth module is being compiled: Undefined symbol sql_drivers_register_all first referenced in main.o Now I had run 'configure' with the '--without-sql-drivers' since I neither have MySQL or PostgresSQL installed on my server. Does this mean I DO have to get either package, install, and run it '--with-sql-drivers'? Or is it that the '--without...' feature doesn't work as intended? Am I making ANY sense? Thanks.

[Dovecot] NFS Stale File Handles on Indexes
by Tony Kay 15 Feb '06

15 Feb '06

The configuration files has settings that seem to address the issues of using indexes on NFS (i.e. locking and mmap fixes), but we are using Dovecot on NFS, and when the load gets high we start to see a lot of NFS stale file handle errors, particularly with MS clients like Outlook. I see the discussion about these errors from last year. Any updates on the state of the code? Should we be using in-memory or local indexes instead for now? - Dovecot 1.0b3 - four physical IMAP servers - mbox format accounts on NFS netapps - currently allowing NFS indexes w/mmap disabled, and using dotlocks -- Anthony Kay University Computing Center (541) 346-1719 GPG Fingerprint: B0DB D46A 60AF FAE7 A94A 5075 0CB4 4D88 9F4F 7F09 Perfection uncanned Like a beautiful redhead Fresh from her trailer from Spam-Ku : Tranquil Reflections on Luncheon Loaf by John Cho
