[Dovecot] v1.1.alpha2 released
by Timo Sirainen 09 Aug '07

09 Aug '07

http://dovecot.org/releases/1.1/alpha/dovecot-1.1.alpha2.tar.gz http://dovecot.org/releases/1.1/alpha/dovecot-1.1.alpha2.tar.gz.sig Hopefully the next release can be v1.1.beta1. I'm not aware of any major problems and I think I'm pretty much done with new features (except for dbox). The largest changes since alpha1: * Removed THREAD indexing. It's a bit buggy and I think there's a better chance of releasing a bugfree v1.1 soon if it's not included. I'll fix it after v1.1. * Removed THREAD=X-REFERENCES2 also because it wasn't as easy to implement with the old threading code. I might put this back though if there's enough interest. * PAM always works in blocking=yes mode now. If you have problems with memory leaks, change auth_worker_max_request_count setting. + Filesystem quota backend supports inode limits, group quota and RPC quota for NFS. + SEARCH and SORT finally compare all characters case-insensitively. We use i;unicode-casemap algorithm. + Config files support splitting values to multiple lines with \ + Winbind NTLM and GSS-SPNEGO mechanism patches by Dmitry Butskoy.

[Dovecot] Not seeing other folders with some clients
by Yves Dorfsman 09 Aug '07

09 Aug '07

Hi, With dovecot 1.0.2, depending on the client I can only see inbox, or all the folders. I see all the folders with pine and balsa, but can see only the inbox with squirel mail and thunderbird. Any idea what's going on here ? Thanks. Yves. ---- Yves Dorfsman yves(a)zioup.com http://www.SollerS.ca

[Dovecot] BUG (and suggested fix) in maildir code
by Tom Vajzovic 08 Aug '07

08 Aug '07

Hi all I'm using dovecot 1.0.rc15 to serve a maildir by IMAP. I have an IMAP subdirectory called subscriptions. The messages are in maidir/.subscriptions/cur/ etc. Dovecot is renaming the directory .subscriptions/ to subscriptions/ This means that when my IMAP client requests this directory, it gets the message "no such directory", and dovecot also gives the error message: dovecot: IMAP(tcv): read() failed with subscription file /var/mail/maildir/tcv/subscriptions: Is a directory The two should be able to live happily side by side, with the subscriptions file called "subscriptions" and the maildir called ".subsciptions". The offending function is maildir_subscriptions_convert_099() in src/lib-storage/index/maildir/maildir-storage.c Can someone with developer access please change this so that rename() is not called if subscriptions is a directory. Thanks, Tom

[Dovecot] dovecot.conf an <TAB> chars
by Sascha Holzleiter 08 Aug '07

08 Aug '07

Hi, I just wanted to "beautify" my dovecot configuration file and as one of the first comments suggests whitespaces and <TAB> should be completly ignored but that doesn't seem to be the case, e.g.: postmaster_address<TAB>= some(a)address.de results in an configuration error as the postmaster_address is not set. Using just a space or replacing the <TAB> char with space chars resolves the problem. This is with dovecot version 1.0.3 on Debian and FreeBSD. Greetings, Sascha

[Dovecot] OpenBSD and too many open files
by Bryan Vyhmeister 07 Aug '07

07 Aug '07

I posted some questions a few months back and received lots of great help in getting my dovecot/postfix/LDAP setup working. Initially, I ran into the pipe failed too many open files error. I am running this setup on OpenBSD/sparc64 4.1-stable and so I put dovecot in its own class and upped the maxfiles setting for that class. This was back with dovecot 1.0 and everything worked fine. I just recently upgraded to dovecot 1.0.2 from ports and now I am having the same problems again. I moved kern.maxfiles for that class from 2048 up to 3404 and yet I still run into the error. When I do, I have to restart dovecot to get things running again. Output of: su -c dovecot root -c 'ulimit -a' time(cpu-seconds) unlimited file(blocks) unlimited coredump(blocks) unlimited data(kbytes) 1048576 stack(kbytes) 8192 lockedmem(kbytes) 634482 memory(kbytes) 1898080 nofiles(descriptors) 3404 processes 1044 sysctl kern.maxfiles gives: kern.maxfiles=3404 My main IMAP accounts reside on this server and I have somewhere in the 25000 range of stored messages. Could this be causing the issue? I only have maybe a dozen other users using this server right now but I am planning on putting 500 users on it soon. I added another heavy IMAP user shortly before these problems started but I don't know if that has anything to do with it or not. Likewise, I am not sure if the dovecot 1.0.2 upgrade had any effect either although it did coincide. Any ideas? Thank you. Bryan

[Dovecot] vfile ACL's
by Benjamin R. Haskell 07 Aug '07

07 Aug '07

(Sorry for the impatience. This was one of several questions in my email from yesterday. I thought I might have better luck being more direct.) Is there a way to set ACL's, using the vfile backend, on a truly global basis? or hierarchically (i.e. .Maildir.Sub inherits from .Maildir)? The wiki page says: "The default ACLs for mailboxes is to give owner all permissions and other users none. Mailboxes in public namespaces don't have owners, so by default no-one can access them." Is this configurable? Thanks, Ben
