[Dovecot] indexes?
by David Lee 16 Oct '06

16 Oct '06

Picture: A set of very similar UN*X IMAP servers all NFS-mounting their INBOX area (traditional Unix format) from a common "/var/spool/mail" area; activity for any given user ought to be within one box although this cannot be 100% guaranteed. There is the risk of multiple simultaneous access (e.g. simultaneous LDA/delivers; simultaneous LDA/deliver and user-driven IMAP update; etc.). So locking is an important consideration. Decent "noac,actimeo=0" seems to address this succcessfully. But indexes... What is the best place for the index files? Logically alongside the INBOX area on the shared-NFS area? Or within each UN*X machine? (Or something else?) And why? Is there documentation of what functionality the index files provide, and how, if at all, this interacts with the locking of INBOXes (and folders). Thanks. -- : David Lee I.T.

[Dovecot] quota dict (mysql)
by Peter Veerman 16 Oct '06

16 Oct '06

Hi, I have dovecot configured to make use of the dict (mysql) plugin in order to keep track of the used quota. First, as you can see in the mysql table output below it seems that values aren't stored correctly. Secondly I get all kinds of database related errors in my mail logs. The (relevant) sections of the configuration files are also included below. My question is, what am I doing wrong?

[Dovecot] System-wide sieve script?
by Ty! Boyack 16 Oct '06

16 Oct '06

In the dovecot LDA documentation, it mentions having sieve scripts located in ~/.dovecot.sieve, which works great for per-user sieve code. I was trying to find out if there was a system-wide sieve script (maybe /etc/dovecot.sieve?) that would hopefully be run first, followed by any per-user sieve code. Anyone know if this is already possible, or if not, if there are any plans to implement this? I'm assuming one could make a kludgey fix by having every .dovecot.sieve include a system-wide file, but that would allow a user to remove that "include" if they choose. I'd like to have a centrally controlled, immutable set of rules that all mail goes through. If I missed something in the wiki or archives, I offer my apologies in advance. Thanks! -Ty!

[Dovecot] LDAP Memory Leak
by Daniel 16 Oct '06

16 Oct '06

Hi Timo I use LDAP auth on a system with around 2000 email account. I use dual OpenLDAP servers. I haven't noticed a leak of memory. Is there any more information and I will have a look to see if I can see anything that might help. Is it only affecting certain machines or all? Regards Daniel Rowe Date: Mon, 16 Oct 2006 02:39:26 +0300 From: Timo Sirainen <tss(a)iki.fi> Subject: [Dovecot] 1.0.rc10 released To: dovecot-news(a)dovecot.org, dovecot(a)dovecot.org Message-ID: <1160955566.5448.126.camel@hurina> Content-Type: text/plain; charset="us-ascii" http://dovecot.org/releases/dovecot-1.0.rc10.tar.gz http://dovecot.org/releases/dovecot-1.0.rc10.tar.gz.sig I've finally read all the mails in the mailing list and in my INBOX. If I haven't replied to some of your mail, please resend it. Remember that since 1.0.rc9 release dovecot.index.cache files will get rebuilt in 64bit systems, and it's probably better to delete them manually so you don't get errors in log files. There are only a couple of issues left in my v1.0-TODO list: - Master process appears to be leaking log fds with kqueue. Could someone again give me access to a system where this happens? - Login process problems. How well does it work now? Hopefully well enough that v1.0 could be released. - LDAP authentication is leaking memory? Can anyone confirm this? Even better, can someone figure out what exactly is leaking? :) Not a v1.0 blocker though. I think v1.0 will be released once no-one has reported any major problems for a Dovecot release in 2-4 weeks. I think login process handling is the only potentially major problem left. There are a few patches from people that I haven't forgotten, but I've decided not to put them into v1.0 anymore: - Filesystem quota group. I don't think it's that important feature, and it might break something. - HFS+ hardlink avoiding - Managesieve - vmailmgr support And finally the changes in this release: * When matching allowed_nets IPs, convert IPv6-mapped-IPv4 addresses to actual IPv4 addresses first. + IMAP: Try to avoid sending duplicate/useless message flag updates + Added support for non-plaintext authentication for vpopmail if it returns plaintext passwords. Based on patch by Remi Gacogne. + Added %D modified to return "sub.domain.org" as "sub,dc=domain,dc=org" (for LDAP queries). Patch by Andrey Panin. - rc9 broke cache files in 64bit systems - deliver works now with mail_chroot - auth cache didn't work properly with multiple passdbs - Fixes to handling CRLF linefeeds in mboxes.
